Types of Aerogel Particles

Aerogel particles are light and porous materials formed from a gel in which the liquid part has been replaced with gas. Aerogels are known for being very light, and they are also very good insulators. Because of this, they are sometimes called "frozen smoke". Aerogels can be produced from different materials, and they come in different types. Below are the various types of aerogel particles:

• Silica Aerogels

  Link to Nano

  Aerogels silica particles are the most common type. They are produced from silica gel, which is also the most popular type of gel. These aerogels are popular for their translucent blue color, and they are very good insulators. Silica aerogels are used in different industries, including construction, where they provide insulation without adding too much weight; in the oil and gas industry, they are used to prevent pipes from getting damaged due to extreme temperatures; and in the space industry, where they protect spacecraft from heat during re-entry.

• Polymer Aerogels

  Polymer aerogel particles are produced from polymer gels. Unlike silica aerogels, they are not as fragile and can be bent without breaking. They can be black or dark brown, and they are mostly used in applications that require aerogels to be exposed to water, such as in the construction of water treatment facilities. Polymer aerogels are also used in applications that require lightweights and flexible aerogels, such as in the manufacturing of flexible electronics.

• Carbon Aerogels

  Aerogel carbon particles are produced from resorcinol-formaldehyde gels. They are black and very porous. Carbon aerogels have a pore structure that allows them to absorb specific molecules and are used for supercapacitors. They can also be used as catalysts in the chemical industry. These aerogels have a large surface area, which means they can speed up chemical reactions.

• Metal Oxide Aerogels

  These aerogels are produced from metal oxides such as aluminum, iron, and titanium. They are good insulators and have high strength. Due to their strength and insulating properties, metal oxide aerogels are used in the construction industry to produce strong and insulated building materials. They are also used in the aerospace industry to manufacture insulated and lightweight spacecraft components.

• Hybrid Aerogels

  Hybrid aerogels are made from both organic and inorganic materials. They have a high thermal resistance and are very strong. Hybrid aerogels are used in different industries, such as the aerospace industry, where they manufacture insulated and lightweight components. They are also used in the automotive industry to produce aerogels that insulate against heat and cold and reduce the weight of vehicles.

Function and Feature of Aerogel Particles

Aerogel particles are small, solid substances that form from a gel consisting of air-filled spaces. They are known for having low density and being lightweight. Aerogels are also known as “solid smoke” because they have a blue color that is visible when light is passed through them. Below is a discussion of the features and functions of these particles.

Function

• Thermal insulation: Aerogel acts as an insulator, which helps to maintain heat in a space or object. Insulation aerogel particles can be used to make blankets or coats that keep people warm in very cold temperatures. Their low thermal conductivity also helps to keep buildings warm without using a lot of energy.
• Lightweight structure: Aerogels are very light and can be used to make structures that do not add a lot of weight. For example, they can be used to make lightweight parts for airplanes and spacecraft.
• Space exploration: Aerogels help scientists collect samples from space. They can be used in missions to capture particles from comets or asteroids.

Features

• Porous nature: Aerogel particles are very small and have spaces between them, which makes them porous. They can have spaces that are smaller than 1 nanometer up to nanometers.
• Low density: Aerogels have low density because they are made of more than 90% air. They are considered one of the lightest solid materials in the world. For example, silica aerogel can have a density of 0.001 g/cm3.
• Thermal insulation: Aerogels have very low thermal conductivity. This means that heat cannot pass through them easily. For example, silica aerogels can have thermal conductivity values of about 1.1 W/mK.
• High surface area: Aerogels have a large surface area that can be more than 700 m2/g. This allows them to interact with different materials.
• Transparency: Some aerogels can allow light to pass through them. For example, silica aerogel can be transparent or translucent.
• Versatility: Aerogels can be used for various applications, such as space exploration, construction, and electronics. They can also be made from different materials, like silica, carbon, and polymers.

Scenarios of aerogel particles

Aerogel particles have a wide range of applications across various industries due to their unique properties, such as lightweight, low thermal conductivity, and high porosity. Here are some common usage scenarios:

• Insulation:

  Aerogel particles are used in insulation materials for buildings, pipelines, and spacecraft. They provide excellent thermal insulation, reducing heat transfer and improving energy efficiency. For example, aerogel blankets are used in cryogenic applications and aerospace vehicles to insulate sensitive equipment and components.

• Oil Spill Cleanup:

  Aerogel particles can absorb oils and organic solvents from water, making them valuable for cleaning up oil spills. The aerogel-based absorbents are lightweight, reusable, and efficient at extracting contaminants from aquatic environments, helping mitigate environmental disasters.

• Biomedical Applications:

  Aerogel particles are explored for drug delivery systems, tissue engineering scaffolds, and biosensors. Their high surface area and tunable properties enable the encapsulation and controlled release of drugs, while their biocompatibility makes them suitable for medical applications.

• Electronics:

  Aerogels are used in electronic devices for thermal management solutions. Aerogel-based thermal interface materials (TIMs) enhance heat dissipation in smartphones, laptops, and other electronics, preventing overheating and improving performance.

• Nanocomposites:

  Aerogel particles are incorporated into polymers, metals, or ceramics to create nanocomposites with improved properties. These nanocomposites have applications in aerospace, automotive, and construction industries, offering lightweight solutions with enhanced strength and insulation.

• Clothing and Gear:

  Brands incorporate aerogel particles into outdoor clothing, gloves, and footwear. For example, the North Face used aerogel in its jackets and boots, providing lightweight insulation for extreme temperatures. These products are suitable for hikers, climbers, and explorers who require insulated apparel with minimal weight and bulk.

• Space Missions:

  Aerogels have been used by NASA in space missions to capture and sample extraterrestrial particles. For instance, the Stardust mission used aerogel collectors to capture comet dust particles, enabling scientists to study the composition of comets. Aerogels are also used in spacecraft thermal protection systems due to their lightweight and insulating properties.

How to choose aerogel particles

When selecting aerogel particles, it is important to consider several factors in order to meet specific needs. This includes the intended application, the required thermal properties, and the desired form factor.

The intended application is an important factor to consider when buying aerogel. The application will define the properties that are most important for the aerogel. For example, for thermal insulation applications, the R-value should be considered. R-value is a measure of thermal resistance. For oil and gas applications, the R-value should be considered because it is critical to protecting personnel from hazardous conditions. Aerogels with high R-value particles should be considered.

Aerogel particles are available in different sizes and forms. They can be found in powder form, granules, or in their nanoparticle form. Particle size can affect the properties of the aerogel. For example, smaller particles can lead to better thermal insulation because they have a higher surface area. However, smaller particles also lead to denser aerogels with reduced porosity. Buyers should therefore consider the particle size to obtain aerogels with the desired characteristics.

Another important factor to consider when buying aerogel particles is the silica content. Silica aerogels are popular because they are less expensive. They are also available in different forms and sizes. Other types of aerogel particles are polymer and carbon aerogel particles. These aerogels have different properties and advantages. Polymer aerogel particles have low weight and high flexibility. They are used in applications where lightweight and flexibility are important. These applications include aerospace and automotive industries. On the other hand, carbon aerogel particles are known for their electrical conductivity. They are used in applications such as supercapacitors and conductive composites.

When buying aerogel particles for resale, it is important to consider the supplier's reputation. Customers will always want to buy from a reputable supplier who delivers quality products. Business owners should read online reviews and testimonials to get information about the supplier. They can also request for references from past clients. Working with a reputable supplier will ensure that quality aerogel particles are delivered.
