摘要：
In order to prepare a new multifunctional textile, SiO2/TiO2 composite aerogel was prepared by sol-gel method, and polydimethylsiloxane (PDMS)/SiO2-TiO2 composite material was obtained by mixing PDMS and SiO2/TiO2 composite aerogel. PDMS/SiO2-TiO2 composites were applied to coat onto the cotton fabrics by dip-pad-cure process to prepare multifunctional textiles. The scanning electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric analyzer, atomic force microscopy were adopted to characterize the treated fabrics, and photocatalysis, hydrophobicity and UV-blocking properties were analyzed. The surface of the cotton fabric after treatment has the micro-nano roughness structure constructed by PDMS/SiO2-TiO2 composite material. The PDMS/SiO2-TiO2 composite material is successfully coated on the surface of the finished cotton fabric. The treated cotton fabric has a water contact angle of 157.7°, the UV protection factor of 122.47, and the photocatalytic degradation ratio for methylene blue of 87.08% after 4 h illumination.
