In this paper, an electroconductive silk fabric is fabricated by electrostatic self assemble of reduced graphene oxide (RGO) and polyaniline (PANI) under acid aqueous solution lower the isoelectric point (pI) of silk. The RGO coated silk fabric (silk-RGO) is prepared by self assemble graphene oxide (GO) sheets on the surface of silk, then the GO reduced to RGO, and aniline (ANI) self-assembled on the surface of silk-RGO in situ polymerization of PANI. The results show that the electrical conductivity of silk is mainly influenced by the composition of outermost layer, the ANI and GO concentration, ANI dipping time also contribute to the electrical conductivity of silk. When PANI self-assembled on the outermost layer of silk-RGO, a blue-green, high conductive and flexible silk fabric with a lower electrical surface resistance of 0.330 K cm⁻¹ was obtained. The SEM shows that RGO sheets formed a thin film on the surface of silk, and PANI deposited on the surface of silk with nanowires. The Raman and FTIR-ATR spectra of silk-PANI and silk-RGO-PANI are presented PANI characteristic peaks, and the thermostability of self-assembled samples enhanced.

本文通过在酸性水溶液降低丝线的等电点（pI）的条件下，通过还原性氧化石墨烯（RGO）和聚苯胺（PANI）的静电自组装，制备了一种导电丝织物。RGO涂层的真丝织物（silk-RGO）是通过在丝绸表面上自组装氧化石墨烯（GO）片材，然后将GO还原为RGO，然后在苯胺（ANI）上在丝绸-RGO表面上自组装而制备的。 PANI的原位聚合。结果表明，蚕丝的电导率主要受最外层组成，ANI和GO浓度的影响，ANI浸入时间也对蚕丝的电导率有影响。当PANI自组装在丝绸RGO的最外层时，是一种蓝绿色，高导电性和柔性的丝绸织物，其表面电阻较低，为0.330 K cm获得^-1。扫描电镜显示，RGO片在丝的表面上形成薄膜，而PANI用纳米线沉积在丝的表面上。Silk-PANI和Silk-RGO-PANI的拉曼光谱和FTIR-ATR谱图显示了PANI的特征峰，并增强了自组装样品的热稳定性。
