摘要

采用Pickering乳液聚合工艺制备苯丙聚合物/SiO₂(PSA/SiO₂)复合乳液。透射电镜(TEM)和傅里叶红外光谱(FT-IR)分析显示复合乳胶粒为典型的草莓型结构,纳米SiO₂通过静电吸附在乳胶粒表面。动态光散射(DLS)结果证实纳米SiO₂作为Pickering乳化剂降低了复合乳液的平均粒径。X射线光电子能谱分析(XPS)结果发现Si—OH亲水基团在复合涂层表面富集。原子力显微镜(AFM)图片显示纳米SiO₂在涂层表面均匀分布且形成微细结构。水接触角(WCA)分析发现复合涂层的超亲水机理符合Cassie的复合接触角理论。

Abstract

The poly (styrene-acrylate)/SiO₂ composite latexes(PSA/SiO₂) were prepared by pickering emulsion polymerization.Transmission electron microscopy (TEM) and fourier transform infrared (FT-IR) spectra results shown that raspberry-like composite latexes were obtained and SiO₂ particles were adsorbed on the surface of latexes.Dynamic light scattering (DLS) disclosed that the average particle size of composite latexes decreased which was attributed to the emulsification of SiO₂.X-ray photoelectron spectroscopy (XPS) confirmed that Si—OH hydrophilic groups were enriched on the surface of composite films.Atomic force microscope (AFM) indicated that SiO₂ particles were uniformly distributed and simultaneously formed the microstructure.Water contact angle (WAC) demonstrated that the superhydrophilic principle of composite films was according to the Cassie's law.
