Abstract
The objective of the current study is to evaluate and determine the effect of monomer concentration of ClAETA on the grafting copolymerization of oxidized cellulose which isolated from peel durian. Four concentrations of ClAETA were used in this study, e.g., 40, 50, 60, and 70%. Several analyses were performed to determine the material characteristic, e.g., degree of grafting, FT-IR, surface morphology, contact angle, degree of swelling, and antibacterial activity. The result showed, monomer concetration plays a significant role to the physical and surface morphology of DAC-ClAETA. The degree of grafting of ClAETA was found in the range of 15-31%, and at the concentration of 50% the grafted oxidized cellulose has 30.4% of degree of grafting. SEM images showed the pore volume has linear correlation to the monomer concetration, it increased the surface roughness. Also, the contact angle confirmed the hydrophilicity and degree of swelling of grafted oxidized cellulose was increase that linear to ClAETA concentration. DAC-g- ClAETA was found antibacterial active against S. aureus, S. epidermis, and C. albicans than DAC.
Highlights
Grafting polymerization between cellulose and monomer is one technique to modify natural properties of cellulose for the wide application
The grafting yield (GY) was determined gravimetrically and calculated as follows according to previous report [10]: GY(%) = [W2–W1]/W1x100% (1) Where W1 is the weight of cellulose before and W2 is the weight of cellulose after grafting
Those result confirmed that the concentration parameter affected the degree of grafting of DACg-CIAETA
Summary
Grafting polymerization between cellulose and monomer is one technique to modify natural properties of cellulose for the wide application. Ethyltrimethylammonium chloride (CIAETA) 50%, temperature 80oC, contact time 180 min in the presence of potassium persulfate as initiator [11], which produced a material which has 30.4% of degree of grafting. A material which has 61.3% of degree of grafting could be obtained by modifying cellulose using methyl acrylate monomer under this following condition: monomer concentration 0.68 mol/L, temperature 50oC, contact time 115 minute in the presence of initiator, potassium persulfate. Those mentioned previous study [11] indicated that the reaction parameter have important role for obtaining an optimized reaction. Based on this literature review, the objective of this current study is to determine the effect of one parameter, in this case
