摘要
本文运用扫描镜对不对称醋酸纤维素膜、含有金属微粒的(W,Nb,Zn,Cr,Fe,Mo,Cu 等)不对称醋酸纤维素共混膜的形态进行了描述,用自动吸附测定仪测定了膜的表面积孔体积、平均孔半径、平衡时单位膜重量吸附氮气的体积等,并探讨了膜的形态及吸附性能与渗透性之间的联系。
This paper describes the morphological structures of asymmetric blended cellulose acetate(CA)membranes and membranes blended with metal particles by SEM.The surface area,the pores volume,the average pore radius and the adsorbed nitrogen volume per membrane weight unit at the equilibriumadsorption have been measured by Sorptomatic 1800.The effect of membrane structures and adsorp-tion properties on gas permeabilities have been investigated.
