摘要:
渗透汽化性能及结构稳定性是复合膜的重要评价指标。采用纳米划痕技术原位表征分离层与支撑体的界面结合强度。以聚二甲基硅氧烷(PDMS)化合物作为膜材料,详细考察管式多孔陶瓷支撑体粗糙度及孔径对PDMS复合膜界面结合强度及渗透汽化性能的影响。结果表明:陶瓷支撑体粗糙度为1 μm,平均孔径为200 nm,制备的复合膜结构稳定性及渗透汽化性能最佳,临界载荷为27 mN,当进料温度为40 ℃ 时,膜对1%丁醇水溶液的通量可达1 139 g/(m2·h),分离因子为22。
Abstract:
Pervaporation performance and structural stability play important roles in the evaluation of composite membranes.An in-situ nano-scratch technique was employed to probe interfacial adhesion between separation layer and porous support layer.Polydimethylsiloxane(PDMS)had been used for the active layer,and the roughness and the pore size of tubular ceramic support layers were evaluated to achieve the composite membranes with simultaneously high structural stability and separation performance.Results indicated that the composite membrane prepared with the roughness of 1 μm and the pore size of 200 nm exhibited the best separation performance and structural stability,the membrane with 27 mN critical load showed a total flux of 1 139 g/(m2·h)and separation factor of 22 for 1% n-butanol-water mixtures at 40 ℃.
