The ionomer membrane under the conditions of 20℃ and 0.05 MPa shows better permeaselectivities that the permeability coefficient of CO_2 and CO_2/ N_2 separation factor are 223 Barrer and 65.70, respectively, while CO_2 / CH_4 separation factor is only 14.70. An obvious increase in P_(CO_2) with decreasing pressure difference exhibits a characteristic of facilitated CO_2 transport, which is not disappear and almost unchange after two months. There is no this behavior for N_2 and CH_4. Hence, P_(CO_2) and α_(CO_2/N_2) and α_(CO_2/CH_4) can be enhanced simultaneously.

The results show that the porosity of the membrane prepared by ScCO_2 induced phase separation is higher than that prepared by conventional method;the membrane structures are significantly influenced by the process parameters;compared with the conventional immersion precipitation phase inversion,ScCO_2 induced phase separation process can effectively avoid the formation of macrovoids at suitable operating conditions;during depressurization process,the great differences in the effect of depressurization time on membranes structure for various polymer materials result from that the speed of CO_2 gaseous nuclei escaping from membrane substrate can not keep the pace with the outer depressurization rate.(2) The tendency that the interaction parameters affect the binodal curve position is illustrated by changing the interaction parameters in reasonable ranges.
研究结果表明:与传统方法相比,采用ScCO_2诱导相转化法可获得更高的膜孔隙率;通过改变操作参数可对膜的结构进行调控,且操作参数对膜结构的影响与铸膜体系的自身性质也紧密相关;在适宜的操作条件下,ScCO_2诱导相转化法能有效避免采用传统的浸入沉淀相转化法制膜时易出现的大空腔结构;泄压过程中CO_2气核从聚合物膜基体中逃逸的速度能否与膜基体外部的泄压速度保持同步,是泄压时间对不同材质膜结构影响截然不同的根源所在。

The damage represents complex mechanism. In this research based on T300/HT3 laminate structure, fatigue life is predicted phenomenologically, dealing mainly with in-plane stresses without accounting for out-of-plane failures such as craze. Fatigue modulus, based on damage mechanics, is used as a physical parameter which helps to describe the basic fatigue behaviors of unidirectional laminates and obtain expressions for cumulative damages defined by strains and stress. Based on some typical fatigue test data for unidirectional composite laminates, residual modulus sequence is found out.
