摘要 |
The present invention relates to an acetylated methyl cellulose-based membrane and a manufacturing method thereof. Specifically, the present invention relates to a manufacturing method of a membrane with an improved chemical durability while maintaining a membrane fouling resistance by mixing acetylated methyl cellulose and cellulose acetate after manufacturing the acetylated methyl cellulose. The membrane manufactured according to the present invention has a cross-section of a sponge structure so as to maintain the membrane fouling resistance and improve the chemical durability at the same time compared to the isolated use of acetylated methyl cellulose or cellulose acetate. |
