摘要：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 omega(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.
