摘要/Abstract

摘要： 本文提出了一种新型硅烷基纳米复合涂层。分子动力学模拟结果证实,多巴胺的引入可以大大降低盐溶液在硅烷涂层微纳米孔道中的传输能力,以及复合涂层界面处水分子和离子的运动能力。对于氧化石墨烯-硅烷涂层来说,水分子可以扩散至硅烷层,与硅烷分子的亲水端形成氢键连接。极限接枝的氧化石墨烯-多巴胺-硅烷复合涂层可以充分发挥硅烷分子的疏水特性,完全阻绝水分子进入硅烷层,使水分子传输深度降低了87.5%。

Abstract: A new silane-based nanocomposite coating is proposed. Based on molecular dynamics simulation results, it is confirmed that the introduction of dopamine can greatly reduce the transport ability of salt solution in the micro-nano channels of silane coating and the movement ability of water molecules and ions at the interface of the composite coating. For the graphene oxide-silane coating, water molecules can diffuse into the silane layer and form hydrogen bonds with the hydrophilic ends of the silane molecules. The extreme grafted graphene oxide-dopamine-silane composite coating can fully utilize the hydrophobic property of silane molecules and completely block the water molecules from entering the silane layer, reducing the water molecule transport depth by 87.5%.

Key words: modified silane, graphene oxide, dopamine, microstructure, hydrophobicity, durability
