Preparation of Copper Sulfide by Microwave Assisted Method and Its Application on Superhydrophobic, Anti-UV and Photocatalytic Cotton Fabric

In this work, solid spherical and hollow spherical CuS were prepared by microwave assisted method with PEG4000 as dispersant. The CuS was characterized by particle size analysis, scanning electron microscope(SEM), nitrogen adsorption and desorption, and X-ray diffraction (XRD), respectively. The effects of PEG4000, ratio of thiourea: copper, and microwave power on particle size of CuS were discussed, and the effects of particle size on photocatalytic property were evaluated. The solid spherical CuS had average particle size of 189.1 nm and specific surface of 9.54 m(2)/g. The hollow spherical CuS had average particle size of 502.7 nm and specific surface area of 16.01 m(2)/g. The results showed the hollow spherical CuS had better photocatalytic property. In addition, the cotton fabric was treated by hollow spherical CuS/polydimethylsiloxane (PDMS) to prepare multifunctional textile in this work. The treated cotton fabric was characterized by SEM. The treated cotton fabric achieved the superhydrophobicity with contact angle of 156.9 degrees and sliding angle of 8 degrees, good photocatalytic properties for methylene blue, and exceptional UV resistance with UPF of 223.52.
