摘　　要：以2,2′,4,4′-联苯四甲酰氯(BTEC)和均苯三甲酰氯(TMC)为有机相功能单体,与间苯二胺(MPD)通过界面缩聚反应制备了一系列反渗透复合膜.系统研究了BTEC的加入对复合膜活性分离层表面化学组成、表面形貌、亲水性及分离性能的影响.结果表明:BTEC的加入,所制得的反渗透复合膜表面趋于平滑,水通量略有降低,脱盐率则由99.42%提高至99.63%.A series of reverse osmosis （RO） composite membranes was prepared by interracial polymerization of 2,2r, 4,4＇-biphenyl tetraacyl chloride （BTEC）/ trimesoyl chloride （TMC） as organicphase monomers and 1,3-phenylene diamine （MPD）. The effects of surface chemical composition, surface morphology, hydrophilicity and separation performance were systematically investigated by incorporating BTEC. The results showed that smooth polyamide structures were formed, the salt rejection of the RO membranes increased from 99.42 % to 99. 63 % while the permeability just experienced a little decrease.
