Abstract
In this work, graphene/Ag (GA/Ag) composite aerogels with the micro rough porous structure and conductive property and polydimethylsiloxane(PDMS) with the low surface energy were used to prepare super-hydrophobic cotton fabric (GA/Ag/PDMS@cotton) with conductive property was successfully prepared. The surface morphologies, chemical composition, wettability, conductive property and microwave absorption property of GA/Ag/PDMS@cotton fabric were characterized. It was shown that GA/Ag and PDMS were successfully coated onto the surface of cotton fabrics. The water contact angle of GA/Ag/PDMS@cotton was 157°. And it could make the luminous diode shining continuously. The treated cotton fabrics exhibited excellent super-hydrophobic and conductive properties. The minimum reflection loss of GA/Ag/PDMS@cotton fabric was − 28 dB, and it had a larger effective absorption bandwidth. In addition, the treated cotton fabric also showed excellent anti-fouling and self-cleaning properties. The GA/Ag/PDMS@cotton fabric cannot be wetted and polluted by water, fruit juice, milk and black tea. And it also had excellent washing durability, acid and alkali corrosion and storage stability.
