摘要：

The core-shell SiO2-fluorinated polyacrylate nanocomposite latex particles containing fluorine in the shell were successfully synthesized by seeded emulsion polymerization with nano-SiO2 as seeds Transmission election microscopy (TEM) confirmed that the resultant particles had the core-shell structure obviously Scanning electron microscopy (SEM), TEM and dynamic light scattering (DLS) analysis indicated that the obtained core-shell nanocomposite latex particles were uniform and possessed narrow size distributions The chemical components of the core-shell nanocomposite latex particles were investigated by Fourier transform infrared (MR) spectrometry and X-ray photoelectron spectroscopy (XPS) analysis, respectively. XPS analysis of the SiO2-fluorinated polyacrylate nanocomposite latex films revealed that the intensity of fluorine signal in the film-air interface is higher than that in the film-glass interface In addition. compared with the film of core-shell SiO2-polyacrylate nanocomposite latex prepared under the similar polymerization condition, the core-shell SiO2-fluorinated polyacrylate nanocomposite latex film showed higher contact angle and thermal stability (C) 2010 Elsevier B.V.
