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。

This results in a higher possibility for the components to enter the unstable demixing gap after the rapid phase separation of the system has taken place.Therefore,a bicontinuous structure is easily formed for CA membrane. For the systems of ScCO_2/toluene/PSt and ScCO_2/solvent/PVB,the increase of temperature or decrease of pressure leads to the binodal curves shifting toward the polymer/solvent axes,and thus results in the decrease of miscibility gap.The membrane toplayers of ScCO_2/solvent/PVB systems are dominated by the equilibrium thermodynamics,while the formation of membranes sublayers is the result of the combination of the equilibrium thermodynamics and membrane formation kinetics.
以下时由双节线、旋节线之间构成的亚稳互溶分相区很窄,使得该体系在快速分相后其组成变化进入旋节线内不稳分相区的可能性极高,从而易导致CA膜形成双连续结构;温度升高或压力减小均可导致ScCO_2/甲苯/PSt与ScCO_2/溶剂/PVB两种铸膜体系的双节线向聚合物/溶剂轴一侧靠近,均相区减小;ScCO_2/溶剂/PVB体系的膜表面结构形成主要受平衡热力学过程的控制,而膜的截面结构是其平衡热力学与扩散动力学共同作用的结果。
