Synthesis and Surface Characteristics of Novel Oligomeric Silane with Perfluoropolyether

Perfluoropolyether(PFPE) has been widely applied in industry because of its very excellent properties of very high contact angle and low surface energy, good lubricant property and antifouling property. But the difficulty to synthesize PFPE has limited the research on this field. In this study, the novel silicon-containing oligomer with perfluoropolyether moiety was synthesized, and the structure was characterized by 19 F-NMR and 1 H-NMR. The surface properties of contact angle, sliding angle, and soil release property were investigated. The results show that PFPE in this study can be utilized as an anti-smudge coating material because it shows lower sliding angle and better soil release property than commercial products.
