Abstract:In order to explore a simple method for preparing an anti-smudge coating. Herein, two fluorinated binary random copolymers with low surface energy was synthesized by solution polymerization. They are Poly [2-(Perfluorooctyl)ethyl methacrylate–r-3-Acryloxypropyl Trimethoxysilane](PFOEMA-r-APTMS) and Poly[2-(Perfluorooctyl)ethyl methacrylate-r-3-(Methacryloxy)propyltriethoxysilane](PFOEMA-r-MPTES), respectively. They were diluted into different concentration solution and sprayed onto glass surface to prepare anti-smudge coatings. The chemical structure of the polymer was characterized by combination of infrared spectroscopy (FTIR) and nuclear magnetic resonance (1H NMR). The surface roughness was measured by atomic force microscopy (AFM), the water contact angle and wear resistance of coatings was also measured. Meanwhile, the relationship between contact angle and the concentration of the polymer solution, as well as the wear resistance, transparency and anti-smudge performance of the coatings under different humidity were studied. The results showed that the wear resistance of coating coated with PFOEMA-r-MPTES was much better than that coated with PFOEMA-r-APTMS. When the mole ratio of PFOEMA to MPTES was 1.5, the dilution concentration of copolymer was 10 mg/mL and the glass treatment humidity was 60%, the glass coated with PFOEMA-r-MPTES shown the best anti-smudge performance, hydrophobicity, wear resistance, as well as high transparency.
