结合贻贝仿生学原理,以钢片为基材,利用多巴胺和硅氧烷的迈克尔加成反应,制备了双疏材料,利用SEM、FTIR、接触角测试等方法对双疏材料进行了表征,考察了它的性能.实验结果表明,制备的双疏材料具有较高的疏水疏油性,水滴和油滴在该双疏材料表面的接触角分别为158°,128°.双疏材料具有优异的耐磨擦性、机械耐久性能、化学稳定性以及在原油中的耐温性,在复杂原油管道运输环境中的应用前景较高.
Preparation and characterization of dopamine-modified wear-resisting amphiphobic materials
The amphiphobic materials were prepared based on a steel sheet by means of Michael reaction of dopamine and siloxane according to mussel-inspired chemistry.The structure of the amphiphobic materials was characterized by SEM,FTIR,and contact angle tests.Besides,their properties were tested.The results show that the amphiphobic materials possess high hydro-oleophobicity properties;the contact angles of water and oil droplets on the amphiphobic material surface were 158° and 128°.Amphiphobic materials show excellent wear resistance,mechanical durability properties,chemical stability,and heat resistance in crude oil and have a high application prospect in complex crude oil pipeline transportation environments.
