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

다국어 초록 (Multilingual Abstract)

In this work, solid spherical and hollow spherical CuS were prepared by microwave assisted method withPEG4000 as dispersant. The CuS was characterized by particle size analysis, scanning electron microscope(SEM), nitrogenadsorption and desorption, and X-ray diffraction (XRD), respectively. The effects of PEG4000, ratio of thiourea: copper, andmicrowave power on particle size of CuS were discussed, and the effects of particle size on photocatalytic property wereevaluated. The solid spherical CuS had average particle size of 189.1 nm and specific surface of 9.54 m2/g. The hollowspherical CuS had average particle size of 502.7 nm and specific surface area of 16.01 m2/g. The results showed the hollowspherical 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 bySEM. The treated cotton fabric achieved the superhydrophobicity with contact angle of 156.9 o and sliding angle of 8 o, goodphotocatalytic properties for methylene blue, and exceptional UV resistance with UPF of 223.52.
