Popis:	In this work, facile preparation and low-cost utilizing durian peel organic waste as a cellulose (DPC) source and copolymerization grafted between 2-[acryloyloxyl]-ethyl trimethylammonium chloride (AETAC) and chitosan were developed. Accordingly, a grafting yield of 21.9 % was obtained. In addition, to further understand the characterization of grafted cellulose with AETAC and cellulose grafted with AETAC and chitosan through techniques, including FTIR, SEM, XRD, TGA, and contact angle confirmed the grafting of AETAC and chitosan monomers onto cellulose backbone (DPC-g-AETAC-co-chitosan). The morphology grafting process resulted in the DPC-g-AETAC-co–chitosan with wrinkle structure, coarse surface, and formation of pores, resulting in a crystallinity index slightly reduced from 36.58 to 19.3 %, however, DPC-g-AETAC-co-Chitosan increased in thermal stability. In addition, DPC-g-AETAC-co-chitosan demonstrated excellent antibacterial and antifungal ability against S. aureus, S. epidermis, and C. albicans
