摘要

醋酸纤维素(CA)复合膜是为潜在的气体输送和抗菌活性量身定制的，通过加入不同的比例(0-8wt)。%)的沸石- cuo (10:1, ZC)复合物。其目的是开发一种具有增强二氧化碳渗透和选择性能的抗生物污染膜。采用原位共沉淀法合成ZC，赋予溶液铸造机理合成膜的形态、结构、热学和性能特征。FESEM分析显示，M0(处女)和M4 (8wt)的孔隙大小从1µm转变为1.4 nm。% ZC)膜。FTIR研究证实了浸渍ZC在制备膜中的存在及其联系。tga测试耐热膜的气体渗透/选择性。与原始CA膜相比，CO2渗透率提高了3倍，CO2/N2选择性提高了2倍。对复合膜进行了革兰氏阴性菌的抑菌试验，结果表明，增加复合膜中ZC的含量，效果显著。

Tailoring Zeolite-Composite (ZC) Impregnated Thermally Endured Nonporous Cellulose Acetate Membranes for Potential Gas Separation and Antibacterial Performances

Cellulose acetate (CA) composite membranes are tailored for potential gas-transportation and antibacterial activity by incorporating various ratios (0-8wt. %) of zeolite-CuO (10:1, ZC) composite. The aim behind this is to develop an anti-biofouling membrane with enhanced CO2 permeation and selection properties. In situ coprecipitation route is adopted to synthesize ZC that imparted morphological, structural, thermal, and performance characteristics of membranes synthesized by solution casting mechanism. FESEM analysis revealed, pores size transformed from 1µm to 1.4 nm as observed in M0 (virgin) and M4 (8wt. % ZC) membranes, respectively. The existence and linkages of impregnated ZC in the developed membranes are verified by FTIR investigations. TGA-tested thermally endured membranes are tested for gas permeation/selectivity. In comparison to virgin CA membrane, three folds enhancements in CO2 permeation and two folds in CO2/N2 selectivity are observed. Membranes are also evaluated for antibacterial test against ‘gram-negative bacteria’ elucidates that increasing ZC content in composite membranes exhibit remarkable results.
