Abstract
Abstract In the present study, antibacterial paper was prepared by mixing chlorhexidine with modified galactomannan. The effects of the oxidation time and citric acid dosages in the modification processes on the physical properties of the paper samples were examined. Also, the effects of the antibacterial agent dosages on the antibacterial properties were studied. The results showed that when the oxidation time was 5 hours, the tensile index, bursting index, and folding endurance increased by 18.4 %, 31.9 %, and 200.0 %, respectively, when compared with the control paper. Also, when the amount of citric acid was 7 %, the tensile index, bursting index, and the folding endurance increased by 20.3 %, 36.6 %, and 195.1 %, respectively, when compared with the control paper. The paper with two modified polysaccharides displayed antibacterial properties against Escherichia coli and Staphylococcus aureus. This study’s elemental analysis results indicated that when the amount of chlorhexidine was 2 %, its retention in paper with oxidized or esterified galactomannans was 1.74 % and 1.59 %, respectively. Furthermore, the SEM results showed that the structures of the bacteria around the inhibition zone were damaged and their activities had been inhibited.
