Cellulosic fabric treated with hyperbranched polyethyleneimine derivatives for improving antibacterial, dyeing, pH and thermo-responsive performance

Abstract

Having cotton fabrics with multifunctional properties is of the most research focused on using either different processes or new and different materials. Improving thermo - responsive and antibacterial properties of cotton fabrics decorated with silver nanoparticles and nanogel has been investigated. During this research silver nanoparticles (AgNPs) have been in situ prepared using poly(N-isopropyl acrylamide)/polyethyleneimine microgel. Prepared particles have been characterized, visualized their morphological structure and their particle through microscopic analysis, which proved that their particle size was in range of (6–10 nm). The decorated gel with silver nanoparticles has been functionalized with silicone compounds to produce hybrid material. The produced gel has been characterized for its pH, temperature, textural, rheological, antimicrobial, cytotoxicity, and conductivity properties. The functional properties of the treated and untreated fabrics have been investigated, and the results proved that treated fabric has conductivity, antibacterial, pH and thermo-responsive properties.
