【摘要】：在涉氢应用领域,氢及其同位素的渗透导致结构材料氢损伤、能源浪费及核污染等诸多问题,在结构材料表面覆盖阻氢涂层是解决氢渗透问题的重要技术手段。总结了传统阻氢涂层的特性及其阻氢效果,并阐明了传统阻氢涂层仍然存在的效率低及寿命短等问题。最新研究表明,石墨烯等二维材料薄膜具有很强的阻挡特性,多层堆垛结构效果尤其明显,可作为优异的阻氢材料,而传统阻氢涂层兼具有一定的吸附储氢性能。通过对氢渗透机理的分析提出引入二维材料作为阻氢层,并结合传统阻氢涂层的储氢特性构建新型阻氢结构模型,阐述了阻氢层的制备应用现状及储氢层的储氢机理,同时探讨了针对不同应用背景下新型阻氢结构的不同形式与应用效果,最后展望了新型阻氢结构涂层在不同应用领域下的应用前景。
[Abstract]:In the field of hydrogen application, hydrogen and its isotopic permeation lead to many problems such as hydrogen damage, energy waste, nuclear pollution and so on. It is an important technical means to solve the problem of hydrogen permeation by covering the surface of structure material with hydrogen resistant coating. The characteristics and effect of traditional hydrogen barrier coatings are summarized, and the problems of low efficiency and short life of traditional hydrogen barrier coatings are expounded. The latest research shows that graphene thin films have strong barrier properties, especially multilayer stacking structure, which can be used as excellent hydrogen barrier materials, while traditional hydrogen barrier coatings have some adsorption and storage properties. Based on the analysis of hydrogen permeation mechanism, a novel hydrogen barrier structure model was constructed by introducing two-dimensional materials as hydrogen barrier layer and combining with the hydrogen storage characteristics of traditional hydrogen barrier coating. The preparation and application status of hydrogen barrier layer and hydrogen storage mechanism of hydrogen storage layer were described. At the same time, the different forms and application effects of the new type hydrogen barrier structure under different application background are discussed. Finally, the application prospect of the new hydrogen resistant structure coating in different application fields is prospected.
