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:

The permeation of hydrogen and its isotope lead to many problems in hydrogen related field,such as hydrogen damage of structural materials,energy waste and environmental pollution etc. Hydrogen permeation barriers prepared on structural materials has become the most promising techniques to prevent the hydrogen penetration. In this paper,the properties of various types of conventional coatings are summarized,furthermore,the existing issues of low efficiency and short lifetime are expounded. Latest research show that two-dimensional (2D) materials membranes,such as grapheme,possess strong impermeability,especially in multi-layer stacking structures,while the conventional coatings also possess definite property of hydrogen adsorption storage. By the analyze of hydrogen penetrate mechanism,the novel hydrogen permeation barrier structure model is proposed,which suggests 2D materials as hydrogen barrier layer combined with the hydrogen storage character of the conventional coatings,the present preparation and application status of the hydrogen barrier layers together with the storage mechanism of the hydrogen storage layers are elucidated,and the application effects of different structure styles for various environments are discussed simultaneously. Finally,the potential applications of the novel structure of hydrogen barriers are prospected.
