Preparation and anti-biological adhesion performance evaluation of ZNO@PSBMA super hydrophilic coating
Source abstract
Abstract
In this study, zinc oxide (ZnO) nanoparticles were modified by means of dispersion using a γ-aminopropyl triethoxysilane coupling agent (KH550), obtaining KH550-ZnO. Then a certain amount of SBMA powder was put into the KH550-ZnO solution, and the ensuing polymerization reaction produced super hydrophilic PSBMA-KH550-ZnO powder. Finally, several polished aluminum sheets were immersed in the PSBMA-KH550-ZnO aqueous solution to start deposition. Upon completion of the deposition, the aluminum sheets were taken out and dried to obtain samples of the ZnO@PSBMA super hydrophilic coating. The structure, morphology and chemical composition of the powders and coatings were investigated by SEM, IR and EDS. The dispersion of KH550-ZnO in aqueous solution was analyzed. The results show that the particle size of KH550-ZnO decreases greatly in aqueous solution. The substrate can be superhydrophilic when deposited in PSBMA-KH550-ZnO aqueous solution for 130 minutes，After 48 hours of coating deposition, the compactness, roughness and friction resistance of the coating are greatly improved. ZnO@PSBMA superhydrophilic coating has good anti-protein, anti-bacterial and anti-algal adhesion properties.
