NOVELTY - Preparation of cellulose acetate composite film involves carrying out immersion precipitation phase inversion modification using cellulose acetate and graphene oxide modified molecular sieve as raw materials. USE - Preparation of cellulose acetate composite film (claimed). ADVANTAGE - The method produces composite film having improved hydrophilicity and water flux, enhanced strength and contamination resistance due to the use of molecular sieve having large specific surface area and graphene oxide having improved working area. The process is simple, economical and produces composite film having improved service life. DETAILED DESCRIPTION - Preparation of cellulose acetate composite film involves carrying out immersion precipitation phase inversion modification using cellulose acetate and graphene oxide modified molecular sieve (ZIF-67-GO) as raw materials.
