合成了双官能化杯[4]芳烃衍生物,并通过共缩聚的方法制备了主链含杯[4]芳烃的聚对苯二甲酸丁二酯-聚二甲基硅氧烷(PBT-PDMS)共聚酯.利用1H-NMR,FTIR,SEC等手段表征了共聚物的组成及分子量.以此共聚物为膜材料,通过刮膜法制备了可用于渗透汽化的致密无孔分离膜,并用SEM表征了无孔膜的膜厚及截面结构.研究了温度和原始液浓度对渗透汽化的影响.该共聚物渗透气化膜分离水中微量苯的分离因子可达491,通量为58g/(m2h). The bifunctionalized calix [4] arene derivatives were synthesized and polybutylene terephthalate-polydimethylsiloxane (PBT-PDMS) with main chain [4] arene was prepared by copolycondensation ) Copolyesters were synthesized and characterized by 1H-NMR, FTIR, SEC and other means.The copolymer was used as the membrane material to prepare the pervaporation dense nonporous separation membrane SEM was used to characterize the membrane thickness and cross-sectional structure of the nonporous membrane. The effects of temperature and initial concentration on the pervaporation were investigated. The separation factor of trace benzene in the water vapor permeable membrane was 491 and the flux was 58g / ( m2h).
