改性纳米SiO2/短氟碳链聚合物复合乳液的制备及拒水性研究
Study on preparation of modified nano-silica/polymer containing short fluoroalkyl chains composite emulsion and its water repellency
摘要
Abstract
Nano-silica modified by γ-methacryloylpropyltrimethoxysilane (MPS) was prepared by the co-condensation of tetraethylorthosilicate (TEOS) and MPS. The modified nano-silica/polymer containing short fluoroalkyl chains composite emulsion was prepared via in-situ emulsion polymerization. The structure, particle size and distribution, and thermal stability of the product were characterized by Fourier-transform infrared (FT-IR) spectrom-etry, particle size analysis and thermal gravimetric analysis (TGA), respectively. The composite emulsion was applied to the polyester fabrics to investigate water repellency. The surface morphologies of untreated and treated fabrics were characterized by scanning electron microscopy (SEM). The results showed that the obtained composite emulsion was quite homogeneous with narrow size distribution and had better thermal stability. The successful encapsulation of modified silica into the composite emulsion increased surface roughness of the treated fabric. The treated fabric had a water contact angle of 151° and a spray rating of 90, indicating that the water repellency of treated fabric was noticeably improved.关键词
