摘　　要：以N-甲基吗啉-N-氧化物（NMMO）为溶剂物理溶解纤维素，是纺织行业中新兴的Lyocell纤维制备过程中采用的溶解方法．本实验室创造性地借鉴此工艺。以NMMO为溶剂制备出新型纤维素膜．本文介绍了纤维素作为膜材料的优点以及溶剂法新型纤维素膜的制备、干燥、改性以及气体渗透性能等．N- methylmorpholine- N- oxide （NMMO） can physically dissolve cellulose, and is widely applied in the process of Lyocell fiber spinning in textile industry. Illuminated by this process and in a creative way our laboratory developed novel cellulose membrane with NMMO as solvent. This article introduced the advantages of cellulose as membrane material, also the preparation, drying, modification and gas permeation performance of cellulose membrane made by solvent method.
