Grafting of prepared chitosan–poly(propylene) imines dendrimer hybrid as a biopolymer onto cotton and its antimicrobial property

چکیده مقاله

<h2 style="text-align: left;">Abstract</h2> <p id="spar0015" style="text-align: left;">Cotton was successfully treated by chitosan&ndash;&ndash;dendrimer PPI hybrid (CS&ndash;PPI) using pad-dry-cure method. Scanning electron microscope (SEM), Fourier transform infra red (FTIR) and weight gain analysis clearly confirmed that CS&ndash;PPI was grafted on cotton through the formation of new chemical bonds. Due to the presence of CS&ndash;PPI on the surface of cotton, the weight gain of cotton was &sim;6% increased, and consequently the antimicrobial activity of the treated fabrics under optimum conditions was raised. As a worthy phenomenon, the treated cotton with CS&ndash;PPI in a concentration of 20% on the weight of the fabric was shown 100% of bacterial reduction.</p>
