摘　　要：为了研究还原氧化石墨烯(RGO)对壳聚糖(CS)薄膜性能的影响,以氧化石墨和CS为原料,通过超声分散和真空诱导自组装法制备了还原氧化石墨烯-壳聚糖薄膜(RGO-CS),研究了薄膜的各项性能,最后分别将CS和RGO用作表面施胶剂,研究二者对瓦楞纸耐水性能的影响。结果表明:成功制备了RGO-CS薄膜;通过SEM观察到RGO-CS薄膜表面平整;未经过还原的GO-CS复合薄膜的电阻率最高,达到了17310 mΩ·cm,而RGO-CS的电阻率仅为52.7 mΩ·cm左右。将RGO-CS和RGO作为助剂对瓦楞纸进行涂布,与空白样对比后发现耐水性显著提高,施胶度分别达到78 s和74 s,接触角最高分别达到112°和110°。In order to study the effect of reduced graphene oxide(RGO)on the properties of chitosan(CS)films,graphite oxide and CS were used as raw materials to prepare reduced graphene oxide-chitosan film(RGO-CS)by ultrasonic dispersion and vacuum induced self-assembly and various properties of the film was characterized in this paper.In addition,CS and RGO were used as surface sizing agents to study the effects on the water resistance of corrugated paper.The results show that:the RGO-CS film was successfully prepared.SEM images reveal the surface of the RGO-CS film is flat and smooth.Besides,GO-CS composite film has the highest resistivity(17310 mΩ·cm),while resistivity of the RGO-CS film is only about 52.7 mΩ·cm.Using RGO-CS and RGO as additives to coat corrugated paper,compared with the blank sample,it is found that the water resistance is significantly improved.The sizing degree reached 78 s and 74 s,and the maximum contact angle reached 112°and 110°,respectively.
