摘要：
In order to improve the hydrophobicity of ultra-high molecular weight polyethylene fabric, micro- and nano-scale structures were built by coating the fabric surface based on the lotus effect. Silica aerogel was dispersed in polyvinylidene fluoride for preparing coating solution, and ultra-high molecular weight polyethylene fabric was coated by the solution. The chemical composition and microstructure of the fabric surface were detected by a X-ray photoelectron spectrograph, a scanning electron microscope and an atomic force microscope. The self-cleaning properties of the fabric were mearsured by the ash collection test. The results show that when the mass fraction of PVDF is 12% and that of the silica aerogel is 8%, the maximum contact angle of the coated fabric surface is 157.8°, and the rolling angle is 3°. The coated film surface has micro-scale projections and nano-scale particle projections. Stain on the coated fabric surface can be taken away by water droplets, so the fabric surface has excellent self-cleaning property.
