摘要：测定了乙醇在环氧树脂（ｅｐｏｘｙ）／氨酯丙烯酸酯树脂（ＵＡＲ）同步互穿网络（ＳＩＮ）内的吸收曲线，它们能被所建立的传递模型络合模型很好地关联．实验结果表明，络合模型所给出的模拟曲线能普遍地关联实验测定的吸收曲线，络合因子ωｒ的物理意义在于乙醇和ＳＩＮ中的亲醇基团发生氢键化．ωｒ和实测的溶解度系数Ｓ、平均扩散系数Ｄ及渗透量Ｐ均与ｅｐｏｘｙ／ＵＡＲＳＩＮ的组成有关，乙醇的传递主要在ＵＡＲ相内进行．
A transport complex model has been established to correlate the experimental absorption curves of epoxy resin(epoxy) and urethane acrylate resin(UAR) simultaneous interpenetrating networks(SINs)with ethanol as the diffusion agent. The experimental results show that the simulative curves calculated can be correlated by using the complex model well enough with the experimental data in general and the physical meaning of correlating coefficient ω r is expressed as the ability of migration of ethanol through the networks after it makes hydrogen bond with urethane, ester or ether groups existing in the networks. Consequently it directly responds to the structures and morphologies of the SINs. The parameters measured including the solubility constant S , average diffusion coefficient D and penetrating weight P are all related to the composition of such SINs. It clearly exhibits that ethanol mainly transports through the UAR phase.
