Abstract
Multifunctional cotton fabric with high electrical conductivity and ultrastrong UV radiation protection properties was successfully fabricated by coating graphene oxide (GO) nanosheet dispersion on fabric surface via vacuum filtration deposition (VFD) method, and then the treated fabric was assembled with polyaniline (PANI) by in-situ chemical polymerization process. The structure and morphological studies showed that the deposition of GO nanosheet is benefit to enhance the uniformity of aniline polymerization on the surface of PANI-GO-cotton fabric. Furthermore, the electrical resistivity of PANI-GO-cotton decrease approximately 106 times compared with control cotton, reached at 48.35Ωcm. PANI-GO-cotton also performed ultrastrong UV radiation protection ability with a UPF value of 445.21, which is superhigher than that of control fabric (UPF rating at 6.86). Moreover, even repeated 10 times water laundering showed nearly no effect on electrical conductivity and UV radiation protection efficiency.
