用慢正电子束多普勒展宽谱研究环氧丙烯酸酯(EA)体系电子束固化(EBC)涂层。S-E曲线给出了稀释剂分子结构及其相对含量、辐射剂量、预聚物和交联剂含量等对EBC涂层微观结构的影响,以及随深度变化的信息。
The electron beam curred(EBC) coating composed of epoxy-acrylates resin as oligomer have been used in vast area. The microstructure of the coating is closely correlated with moleculers structure the components and radiation dose during curing. The S-parameter of positron annhilation doppler broadening was measurred as a function of positron energy to study electron irradiation induced polymerization and crosslinking. The correlations of S-parameter with content, moleculers structure of reactive diluent, and irradiation dose were observed.
