For functionalized types, -COOH, -OH, -NH2, dispersions can be customized.
Carbon nanotubes (CNT) for invisible coatings/paints:
CNTs/carbon nanotubes show good absorption characteristics as absorbers, and the prepared absorbing coatings also have excellent mechanical properties. They are the key research materials in the field of invisible absorbing coatings.
At present, the application of carbon nanotubes' absorbing properties is to add them to polymers as absorbers to prepare absorbing composite materials with both absorbing properties and excellent mechanical properties. The composite of carbon nanotubes and polymers can complement the advantages of the component materials and economically and effectively utilize the unique wave absorption and mechanical properties of carbon nanotubes.
Its main advantages are: small amount of absorbent added, low composite density, easy to obtain lightweight composite materials; strong electromagnetic wave absorption capacity and wide absorption frequency; while having wave absorption performance, it also has good mechanical properties of composite materials.
