Influence of monomer concentration on the morphology, contact angle, water uptake, and antibacterial activity of grafted cellulose obtained from peel durian

The objective of the current study is to evaluate and determine effect monomer concentration ClAETA on grafting copolymerization oxidized cellulose which isolated from peel durian. Four concentrations were used in this study, e.g., 40, 50, 60, 70%. Several analyses performed material characteristic, degree grafting, FT-IR, surface morphology, contact angle, swelling, antibacterial activity. result showed, concetration plays a significant role physical morphology DAC-ClAETA. was found range 15-31%, at 50% grafted has 30.4% grafting. SEM images showed pore volume linear correlation concetration, it increased roughness. Also, angle confirmed hydrophilicity swelling increase that concentration. DAC-g- active against S. aureus, epidermis, C. albicans than DAC.
