abstract

  • Arevolutionary and straightforward technique
    with a dual functionality was manipulated for preparing
    graphene sheets (O-GRP) decorated with O-carboxymethyl
    chitosan nanoparticles (CMChNPs). Graphene was successfully
    exfoliated and decorated with CMChNPs through
    a simple ultrasonication tool. The developed graphene
    sheets were then utilized as the green binder for coating the
    surface of textile with the Ppy-Ag nanocomposite. A new
    vapor polymerization was used to synthesize the nanocomposite
    of polypyrrole-Ag on the graphene-modified fabric
    for acquiring ternary modified textiles (CT/O-GRP-Ppy-
    Ag). The structure and surface morphology of CMCh, O-GRP, and the various coated textiles have been carefully
    approved using various spectroscopic and microscopic
    analysis. The thermal stability, mechanical properties
    besides their electrical resistance, antimicrobial, and flame
    retardancy behaviors for the coated fabrics were investigated.
    The as-fabricated textile composites attained an inferior
    electrical resistance as 0.05 kXthan that for the virgin
    textile (2770 kX) as an indication for the high conductive
    fabrics. The inhibition diameter zone for modified textiles
    was recorded as 24, and 28 mmfor the E.coli, and S. aureus
    bacterial strains, respectively. Moreover, the rate of burning
    and LOI values for CT/O-GRP200-Ppy-Ag were significantly
    improved to 30.9 mm/min, and 22.8%, respectively
    compared to uncoated textile (149.3 mm/min, 17.8%), and
    the blank CT/O-GRP200 (79.2 mm/min, 19.9%) confirming
    the enhanced retardation against the fire growth.
