摘要：用乙二胺（EDA）和氢氧化钠对涤纶织物进行改性，得到氨基化改性涤纶。将改性涤纶浸渍氧化石墨烯
（GO）溶液，涤纶表面的 GO 还原成还原氧化石墨烯（RGO）后得到具有导电性能的涤纶织物。采用 SEM 和
Raman 光谱对导电涤纶织物进行表征，并对其耐洗和耐摩擦性能进行了测试。结果表明，涤纶织物经 150 mL EDA/L
浴液和 50 g/L 氢氧化钠改性后对 GO 的吸附能力增强，织物导电性增加；改性涤纶的最佳导电整理工艺条件为：
GO 溶液质量浓度为 2 g/L，pH=6，6 g/L 保险粉在 95 ℃还原 60 min。在该条件下，织物上 GO 能够被较充分还
原，改性涤纶的表面电阻值为 14.575 kΩ。SEM 结果表明，未经改性的涤纶织物表面光滑，经导电整理后织物
表面覆盖一层石墨烯薄膜；Raman 光谱证实涤纶织物表面沉积了 RGO，且织物上的 GO 被较充分还原。

Abstract: Polyester fabrics were modified with ethylenediamin (EDA) and sodium hydroxide to obtain
amino modified polyester fabrics. After impregnating the modified polyester fabrics with graphene oxide
(GO) solution, GO on the surface of the polyester fabrics was reduced to reduced graphene oxide (RGO) to
obtain conductive polyester fabrics. The samples were characterized by SEM and Raman spectra. The
rubbing resistance and washing fastness of the samples were also tested. The results showed that the
absorption capacity of polyester fabrics for GO obviously increased after being modified by 150 mL EDA/L
and 50 g/L sodium hydroxide. In addition, the conductivity of the fabrics increased. The best conductive
finishing conditions of modified polyester fabrics were obtained as follows: mass concentration and pH
value of the GO solution being 2 g/L and 6, sodium hydrosulfite 6 g/L, reduced at 95 ℃ for 60 min. Under
these conditions, GO on the fabrics could be fully reduced, the surface resistance value of the modified
polyester fabrics was 14.575 kΩ. SEM results showed that the surface of unmodified polyester fabrics was
smooth, after impregnating with GO, GO formed a thin film on the surface of the fabrics. Raman results
revealed that GO was deposited on the surface of polyester fabrics, and GO was fully reduced to RGO.
