This project utilizes renewable, biodegradable, and inexhaustible water hyacinth fiber as a cellulose source for the production of cellulose acetate (CA) membrane. The project aims to develop water filtration membrane technology derived from natural fibers of invasive non-wood plants blended with conducting polymer as an antimicrobial agent and surface modifier. Cellulose fiber isolation will be done using the extraction method, followed by bleaching and chemical treatment of the extracted fibers. Isolated cellulose will be dried and reacted with acetyl group to form cellulose acetate at varying degrees of substitution that can be dissolved in certain solvents. Subsequent in-situ oxidative polymerization of doped polyaniline (PANI) with varying loading of oxalic acid as dopant in the resulting solution is followed. Synthesis of doped polyaniline/cellulose acetate (PANI/CA) membranes is performed using phase inversion techniques employing various loading of pore-forming additive. The resulting doped PANI-CA membrane is characterized for its chemical characteristics, surface morphology, water contact angle, water permeability, and antibacterial properties. This technology provides a sustainable and low-cost alternative to the present CA membranes for water purification processes.
