Abstract
In this research, a nanocomposite of TiO2-SiO2/chitosan (3:1) has been carried out on the cellulose with the help of cross link of citric acid and synergized by using catalyst sodium hypophosphite. The coating was conducted by dip-spin coating method. The study showed the effect of catalyst sodium hypophosphite on increasing of citric acid cross link. The optimum composition ratio of citric acid binder concentration to hypophosphite sodium catalyst (5:3), concentration of citric acid 1.5 M, with time of immersion of citric acid binder for 12 hours. SEM characterization showed that coated cottons using a catalyst sodium hypophosphite had an increase and a uniform distribution of TiO2-SiO2/chitosan nanocomposites compared with coated cotton without the use of a catalyst. The FT-IR analysis showed the difference in the intensity of the C = O streching group at the wave number of 1700 cm-1 which signified the covalent interaction of esterification. The indication of antifungal textiles was shown in the inhibition zone of Candida albicans which was greater than Aspergilus niger inhibition zone of 14.4 mm and 12.9 mm. Keywords : Cotton textile, Citric acid, Sodium hypophosphite, C.albicans, A.niger
