| Summary: | This study is to develop a novel method for fabrication of the chitosan/cellulose triacetate (CTA) laminated membrane as to improve antifouling and biocompatibility of membrane for water filter by used phase inversion technique. 1% w/v of Chitosan was dissolved in 1% acetic acid aqueous solution. 7.5% Cellulose Triacetate (CTA) was dissolved in Dichlorometahe and tert-butanol. Both solutions then added with PG1 to form bonding between them. By using the film applicator, the laminated membrane was fabricated by casting the CTA film on top of the chitosan film and the membrane was produced by immersed the laminated film into diethyl ether to from the pores. The thickness of the film membrane was control using filler gauge before the casting process. Flux, Fourier Transform Infrared (FTIR) and Differential Scanning Calorimeter (DSC) testing were done as to characterize the laminated membrane. |
