Whisker carbon nanotube powder

Conductive coatings are functional coatings that have the ability to conduct electrons and eliminate accumulated charges. They are highly favored in aerospace, electronics, petrochemicals and other fields. Among the many types of conductive coatings, common conductive fillers include metallic fillers such as silver powder, nickel powder, and copper powder, and carbon structure conductive fillers such as carbon black, graphite, and carbon fiber. Among them, carbon nanotubes in carbon structure fillers have a large long diameter and good conductivity. Due to their light weight and low density, they are not easy to precipitate in coatings, so they are gaining more and more attention in the field of conductive coatings....

Application of Whisker Carbon Nanotube Powder in Coatings

◀ Conductive Electrostatic Coatings

Conductive coatings are functional coatings that have the ability to conduct electrons and eliminate accumulated charges. They are highly favored in aerospace, electronics, petrochemicals and other fields.

Among the many types of conductive coatings, common conductive fillers include metallic fillers such as silver powder, nickel powder, and copper powder, and carbon structure conductive fillers such as carbon black, graphite, and carbon fiber.

Among them, carbon nanotubes in carbon structure fillers have a large long diameter and good conductivity. Due to their light weight and low density, they are not easy to precipitate in coatings, so they are gaining more and more attention in the field of conductive coatings.

◀ Electromagnetic Shielding Composite Coatings

Nowadays, the rapid development of electronic technology and the popularization of communication equipment have affected all aspects of people's lives, but the electromagnetic interference and electromagnetic radiation that come with it are endangering people's health.

At present, electromagnetic shielding composite coatings are a hot topic of research, and conductive fillers are one of the key components in its composition.

Similar to conductive coatings, in electromagnetic shielding coating systems, by adding a certain amount of carbon nanotubes, the coating can show electromagnetic shielding effects, which can effectively reduce electromagnetic interference after use.

The study found that by increasing the amount of carbon nanotubes in the electromagnetic shielding coating, the shielding ability of the coating can be gradually enhanced; when the addition amount is the same, the smaller the diameter of the carbon nanotubes, the greater the probability of their mutual contact in the process of forming the power grid chain, which is conducive to forming a good conductive network. Therefore, the shielding effectiveness of the coating increases with the decrease of the diameter of the carbon nanotubes.

◀ Stealth absorbing coating

Stealth absorbing coating is an important breakthrough in modern stealth technology and is widely used in aircraft, radar and other equipment.

This type of coating is mainly composed of a binder and an absorber. The binder is the main film-forming material, and the electromagnetic parameters of the absorber greatly affect the absorbing performance of the coating.

At present, the absorbers used in the industry mainly include conductive carbon black, ferrite, ultrafine powder of metallic properties, carbonyl iron, nano absorber, etc. Among them, whisker carbon nanotube powder as an absorber shows good absorption characteristics. The prepared absorbing coating also has excellent mechanical properties and is a key research material in the field of stealth absorbing coating.
