油井管长效超双疏涂层的构筑及防腐机理研究

In the face of the national drag reduction and anticorrosion of oil pipelines, superamphiphobic coatings in corrosive media are used as the research object. Based on the subject frontiers, concepts of superamphiphobic surface, microcapsule and self-repairing are introduced in the design and fabrication of functional coatings. The worn surface of polymer coating can realize superamphiphobic by fast self-healing. The designed functional coating provided with superamphiphobic characteristics, significantly improved the unique properties of anticorrosion, drag reduction and wear resistance for a long time..Some key scientific problems including preparations of superamphiphobic coatings, control of micro-structure, relationship between chemical components and micro-structure versus wettability, relationships of chemical components and micro-structure versus drag reduction and anticorrosion are investigated systematically. The aim is to find those internal regularities. Studies would be carried out by the high cross of bionics, chemical engineering, anti-corrosion and tribology to achieve remarkable breakthroughs in the preparation of superamphiphobic coatings, control of chemical components and micro-structure, control of surface wettability, and the mechanisms of anticorrosion and wear resistance under corrosive conditions.

面对国家油气管道防腐、减阻的新需求，以腐蚀性介质中功能涂层为研究对象和突破点，立足于学科前沿，将超双疏、微胶囊、自修复等概念引入到功能一体化聚合物基防腐涂层设计与制备中，使得涂层表面即使磨损后新暴露表面可快速自修复仍为超双疏表面，可长期保持超双疏防腐、耐磨特性，从而大幅提高管道涂层的减阻、防腐耐磨效果。.拟采用实验研究、微观分析和建立相关模型相结合的方法，对聚合物超双疏复合涂层的制备与调控、化学组成-微结构与润湿性、组成-微结构与腐蚀行为及防腐耐磨机理等关键科学问题进行深入研究，揭示内在规律性。通过仿生、化工、防腐及摩擦学高度交叉性研究，力争在超双疏复合涂层的制备与调控，表面润湿性调控，典型化工介质中超双疏涂层腐蚀行为、防腐耐磨机理等理论方面取得显著突破。
