Preparation of super-hydrophobic cotton fabrics with conductive property based on graphene/Ag composite aerogels

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 degrees. 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.

Automated summary

Graphene/silver/polydimethylsiloxane-coated cotton fabric with super-hydrophobic and conductive properties was successfully prepared, exhibiting outstanding performance such as a water contact angle of 157 degrees and a larger effective absorption bandwidth.
