High reliable electromagnetic interference shielding carbon cloth with superamphiphobicity and environmental suitability

Abstract It is nowadays essential to avoid electromagnetic interferes (EMI) not only in electronic equipment but also in human health with the rapid development of electronic technology. Damage or invalid in complex and harsh environments is still one of the major challenges facing the field of EMI shielding materials, but superhydrophobic surface have recently shown potential to enhance mechanical stability and chemical durability for this material. As one of the vital research directions of superwetting field, superamphiphobic surface have been often used to solve problems of other fields to improve their surface properties. Therefore, combining the superamphiphobic surface to overcome the problems of electromagnetic shielding materials is the main work of this paper. Here, a superamphiphobic surface was introduced through constructing micro-nano structure with low surface energy, which was mainly contributed from 1H,1H,2H,2H-perfluorodecyltriethoxysilane, micro-ordered array polypyrrole, multi-walled carbon nanotubes and silica. Finally, the as-prepared materials after 5000 times of kneading-releasing cycles, 60 min of ultrasonic, 50 times of abrasion by using sandpaper, 24 h of ultraviolet irradiation, and 10 h of immersion in acid, alkali and different organic solvents, still has superamphiphobic performance which means it can be used extreme environment to endow a widely applications for EMI shielding materials.
