摘要

Abstract

The core-shell nano-SiO2/fluorinated polyacrylate emulsion containing fluorine in the shell was synthesized via in-situ emulsion polymerization in the presence of reactive anionic emulsifier and nonionic emulsifier

with the core phase consisting of nano-SiO2 modified by γ-(methacryloxy）propyltrimethoxy silane (KH-570)

methyl methacrylate (MMA)

butyl acrylate (BA）and acrylic acid (AA)

and the shell phase monomer consisting of methyl methacrylate (MMA)

butyl acrylate (BA）and dodecafluoroheptyl methacrylate (DFMA).The influence of the amount of nano-SiO2 and fluorine-containing monomer (DFMA）on the emulsion polymerization process and surface hydrophobic properties of the latex films was discussed.The nano-SiO2/fluorinated polyacrylate emulsion and its films were characterized by transmission electron microscopy (TEM)

differential scanning calorimetry (DSC)

thermogravimetry (TG)

contact angle (CA）and X-ray photoelectron spectroscopy (XPS）analysis.The results showed that the resultant particles had core-shell structure and a gradient distribution of fluorine in the latex films was formed.The core-shell nano-SiO2/fluorinated polyacrylate latex film showed higher hydrophobicity and thermal stability comparing with fluorinated polyacrylate latex film due to the addition of nano-SiO2.
