                 摘要:采用超声氧化剥离法制备氧化石墨烯(GO),通过浸轧-还原法得到一种高效、简单制备还原氧化石墨烯
                 (RGO)导电棉织物的方法。探讨了 GO 质量浓度、GO 溶液 pH、还原条件、浸轧-还原次数等因素对 RGO 整
                 理棉织物表面电阻的影响,采用 SEM 和 Raman 光谱对整理棉织物进行表征。结果表明,棉织物用质量浓度
                 2.5 g/L、pH=6 的 GO 溶液浸轧后,再用质量浓度 5.0 g/L 的保险粉于 90  ℃对浸轧 GO 烘干后的棉织物还原 30 min,
                 得到的整理棉织物表面电阻降低至 2220  Ω,经过 4 次和 8 次浸轧-还原后棉织物表面电阻可分别降低至 0.22 和
                 0.13 kΩ。通过 SEM 观察整理棉织物发现,RGO 能在棉纤维表面形成薄膜并包覆纤维,且随着浸轧-还原次数的
                 增加,棉织物表面沉积的 RGO 逐渐增多。Raman 光谱较好地证实了 GO 在棉织物表面的沉积,且 GO 较充分地
                 还原成 RGO。通过对整理棉织物的耐洗性能测试发现,整理织物的导电耐久性较好。

                 Abstract: Graphene oxide (GO) was prepared by ultrasonic oxidation stripping method. A highly efficient
                 and simple  method for the preparation of reduced graphene oxide (RGO) conductive cotton fabrics was
                 developed, in which, the cotton fabrics was immersed by GO solution, then, the GO padded cotton fabrics
                 was  dried, finally the reduced graphene  oxide  (RGO)  coated  conductive  cotton  fabrics  was  obtained  by
                 chemical  reduction.  The  effects  of  GO  mass  concentration,  GO  solution  pH  value,  reduction  condition,
                 padding-reduction times on the surface resistance of cotton fabrics were investigated. The treated cotton
                 fabrics were characterized by SEM and Raman spectra. The results showed that the optimal conditions were
                 obtained as follows: GO mass fraction of 2.5 g/L, pH value of GO solution of 6, sodium hydrosulfite mass
                 fraction  of  5.0  g/L,  reduced  temperature  90  ℃  and  reaction  time  30  min.  Under  these  conditions,  the
                 surface resistance of the treated cotton fabrics was decreased to 2220 Ω, 0.22 kΩ and 0.130 kΩ after 4 and 8
                 times of padding-reduction process, respectively. SEM results revealed that RGO could form film on the
                 surface of cotton fiber and cover the fiber, and with the increase of the number of padding reduction, the
                 deposition of RGO on the surface of cotton fabrics increased gradually. Raman spectra results showed that
                 GO was deposited on the surface of cotton fabrics and fully reduced to RGO. Moreover, the conductive
                 durability of the treated fabric was excellent.
