带正电荷的纳滤膜通常表现出优异的抗菌性和抗氧化性。具有高耐溶剂性的纳滤膜在工业废水分离中也有特殊应用。醋酸纤维素因其综合性能而被用于制备各种分离膜。LSCF（La0.6Sr0.4Co0.2Fe0.8O3）是一种阴极和电解质材料，在水溶液中表现出良好的导电性。将纳米亲水性无机添加剂LSCF添加到铸膜液中，以改善醋酸纤维素纳滤膜的性能。在与戊二醛和三氯二羟丙基三甲基氯化铵（TTAC）反应后，所制备的膜表现出带正电荷的特性和优异的耐溶剂性。
Positively charged nanofiltration membranes often exhibit excellent antibacterial and antifouling properties. Nanofiltration membranes with high solvent resistance also find special applications in industrial waste water separation. Cellulose acetate is used to prepare various separation membranes due to its comprehensive performance. LSCF (La0.6Sr0.4Co0.2Fe0.8O3), a kind of cathode and electrolyte material, shows good conductivity in water solution. The nanosized hydrophilic inorganic additive LSCF is added to the casting solution to improve the performance of cellulose acetate nanofiltration membranes. After reaction with glutaraldehyde and trichloro dihydroxypropyl trimethylammonium chloride (TTAC), the prepared membrane demonstrates positively charged characteristics and excellent solvent resistance.
