Preparation of new superamphiphobic coating based on polyurethane (PU) –SiO2 nanoparticle (NP) abstract
In this work, a new superamphiphobic polyurethane (PU) – SiO2 nanoparticle (NP) coating is designed. For this purpose, the effective parameters on surface tension and durability of the synthesized coating investigated and optimized. This noble superamphiphobic coating exhibits good repellent for water and oil with contact angles (CAs) of 159° and 140°, respectively. The synthesized PU-SiO2 nano composite also retains an excellent amphiphobicity after a 7 days of immersion in water with water and oil with CAs of 150° and 130°. This coating is prepared from modifying silica nanoparticles with Flouro alkyl silane and using GPTS coupling agent and poly urethane resin with purpose to strengthen the interaction between PU resin and silica nano particle and enhace adhsion sol to substrate ,respectively
