抄録

  To investigate the influence of electron beam (EB) irradiation on water absorption of acryl resin, the acryl resin samples before and after the irradiation were dipped in the water at 353 K. The water absorption increased the mass (1.81 mass% at 10<sup>5</sup> s) of irradiated acryl resin, which mass was larger than that (1.75 mass% at 10<sup>5</sup> s) before irradiation. When the absorption time was less than 10<sup>4</sup> s, the EB irradiation tremendously increased the mass (0.054 mass%) of absorbed water. Based on surface energy and extended Fowkes theory, the influence of EB irradiation on the water absorption was evaluated to discuss the mass increase induced by EB irradiation. It strongly enhanced the acryl solid-liquid interfacial energy (interfacial energy) of water, which was higher than those of n-hexadecane and 1-bromonaphtalen. EB irradiation increased the interfacial energy of hydrogen bond strength. Based on ESR results, EB irradiation broke the weakly bonded pairs and formed the dangling bonds in acryl resin, whereas water absorption annihilated the dangling bonds. The influence of electron beam (EB) irradiation on water absorption of acryl resin was mainly explained by the dangling bond formation in acryl resin.<br>
