SiO2-CIP/PDMS超疏水防除冰涂层的制备及性能研究
Preparation and Performance Study on SiO2-CIP/PDMS Superhydrophobic Anti-icing/Deicing Coating
摘要
Abstract
Icing is a common natural phenomenon in life,but when ice accumulates on surfaces such as infrastructure or vehicles,it will inevitably affect their safe operation,resulting in the risk of equipment failure,and even safety accidents.Therefore,it is of great practical significance to study the anti-icing/deicing mechanism on the surface of materials and prepare functional coating materials with anti-icing/deicing properties to prevent icing on the surface of equipment,which helps to improve the reliability of various equipment.Inspired by the super hydrophobic properties of lotus leaves in nature,this paper combined with the sunlight responsiveness of Carbonyl Iron Powder(CIP)dark metal particles from the perspective of improving the surface hydrophobicity of materials,took PDMS as the substrate,introduced CIP into it,and then modified the surface of SiO2 nanoparticle,finally obtained SiO2-CIP/PDMS super hydrophobic anti-icing/deicing coating.The results show that the static contact angle of the coating is as high as 159.7°±2°,the rolling angle is as low as 2.7°±1°,the icing delay time is as long as 1120s,and the ice adhesion strength is as low as 78.33kPa.In summary,the coatings prepared in this paper have excellent superhydrophobic,self-cleaning and excellent anti-icing/deicing properties,and have certain sunlight response,which has good prospects for outdoor anti-icing/deicing applications.关键词
