摘　　要：通过改进Hummers法制备氧化石墨烯(GO),采用层层自组装法将氧化石墨烯和壳聚糖(CS)组装在涤纶织物表面构成CS/GO复合膜.通过扫描电子显微镜、傅里叶变换红外光谱、X射线衍射表征氧化石墨烯的形貌、化学组成及层间距;采用扫描电子显微镜、织物感应静电仪分析CS/GO复合膜织物的表面形貌结构和抗静电性能.研究发现,GO和CS成功地交替组装在涤纶织物表面,改性织物的吸水率和抗静电性得到改善.其中,CS质量浓度为2g/L,组装5层复合膜的织物,其静电半衰期值从181.54s下降至2.44s,且耐水洗性良好.Graphene oxide（GO） was prepared by modified Hummers method.The chitosan/graphene oxide（CS/GO）was deposited on the surface of fabric by using layer-by-layer self-assembly to constitute the CS/GO composite film.And the surface morphology,chemical composition and interlayer spacing of graphene oxide were characterized by scanning electron microscopy,Fourier transform infrared spectroscopy and X-ray diffraction.And the surface morphology and antistatic properties of modified fabric were analyzed by scanning electron microscopy and fabric inductive electrometer.The results show that GO and CS are successfully assembled on the surface of the polyester fabric,and the hydrophilicity and antistatic properties of themodified fabric are greatly improved.Among them,the electrostatic half-life of the polyester fabric which is assembled with 5-layers of CS/GO composite film and whose concentration of CS is 2 g/L decreases from 181.54 s to 2.44 s,and the washability of the modified fabric is good.
