Optimization of thermal and hydrophobic properties of GO-doped epoxy nanocomposite coatings

Corrosion and icing are common problems in aerospace and wind power fields. In order to improve the thermal and hydrophobic properties of epoxy-based anticorrosive coatings and expand the application in various working environments, the modified graphene oxide (GO) was introduced into the epoxy-based anticorrosive coatings to prepare GO/polyvinyl butyral/epoxy resin nano composite coatings. The preparation process of nanocomposite coating was optimized by response surface method. Through heat transfer experiment and contact angle experiment, the fitting model of influence factors and response values were established, and the response surface was optimized with heating rate and contact angle as response value. It is reported that the heating rate of the optimum parameter is 0.218 degrees C/s, and the contact angle is 85.757 degrees. The maximum error of the optimized response values verified by the coating experiment is 8.58%, which indicates that the reliability of the RSM optimization result is high. The optimization results of the preparation process parameters can meet the requirements of the nanocomposite coatings with high thermal and hydrophobic properties.
