Synthesis of conductive elastic film and conductive fabric based on crosslinked carboxymethyl starch-AgNPs composite


Keywords: , , ,

The current work is developing a novel, facile and eco-friendly method for synthesis of highly concentrated silver nanoparticles (AgNPs) using AgNO3 as a precursor, the eco-friendly carboxymethyl starch (CMS) polymer as both reducing and stabilizing agent and glycerol as a plasticizer. (4-trimethyl ammonium methyl) benzophenone chloride)/UV eco-friendly system was utilized for further synthesis of AgNPs and for grafting of N, N-methylene diacrylamide onto CMS-AgNPs composite to obtain crosslinked CMS-AgNPs. After crosslinking, the produced composite either: 1) dried in a Teflon coated petri dish followed by exposure to UV-irradiation or 2) dried on the surface of a textile fabric followed by exposure to UV-irradiation. An insoluble elastic gel film was produced in both cases. The produced crosslinked CMS-AgNPs film or fabric coated crosslinked CMS-AgNPs film showed a measurable electrical conductivity, elasticity and water absorption properties. Colloidal solution of AgNPs was characterized by UV-Vis spectroscopy. Film and fabric were characterized by, TEM, SEM, EDS and TGA. The obtained properties of the film or fabric render it for utilization as a polymer gel electrolyte in the dye-sensitized solar cells (DSSC) fabrication.
