Synthesis and Properties of Nano-TiO₂ Modified Fluorine-Containing Polyacrylate Soap-Free Emulsion

Abstract

Nano-TiO 2 Modified Fluorine-Containing Polyacrylate Soap-Free Emulsion was Successfully Synthesized via Soap-Free Emulsion Polymerization Technique, in which the Polymerization Monomers Consisted of Methyl Methacrylate (MMA), Butyl Acrylate (BA) and Dodecafluoroheptyl Methacrylate (DFMA). the Influence of Amount of Initiator, Emulsifier, Containing Fluorine Monomer and nano-TiO 2 on the Performance of Emulsion was Investigated. the Results Showed that the Good Polymerization Stability, and High Monomer Conversion were Obtained when the Amount of Ammonium Initiator was 1.2%, the Amount of Reactive Emulsifier was 3.5%. with Increasing Amount of DFMA, the Monomer Conversion Decreased and the Gel Rate Increased Gradually with the Increase of DFMA Amount. UV-Blocking Ability of the Cotton Fabric Treated with the Hybrid Emulsion Containing Nano-Tio 2 increased with Increasing Amount of Nano-TiO 2 . IR Spectrum Results Showed that Nano-TiO 2 and Fluorine-Containing Monomer were Successfully Introduced in the Segmental Structure of the Polymer. SEM Revealed that Nano-TiO 2 was Loaded on the Surface of the Treated Cotton Fabric which had Good Hydrophobicity.
