摘　　要：利用改进的Hummers法制备氧化石墨烯/聚氨酯整理剂(GO/WPU)和石墨締/聚氨酯整理剂(rGO/WPU),分别对涤棉基、棉基织物进行浸轧整理,测试几种织物的防辐射功能与强力、透气性等性能,对比分析各指标变化趋势,得到最佳工艺参数。结果表明,先还原后整理得到的石墨烯织物的电磁辐射屏蔽效能优于先整理后还原得到的石墨烯织物;石墨烯质量浓度为10 mg/mL时制备的涤棉基石墨烯织物(先还原后整理)电磁屏蔽效能最佳,可达25.3 dB。Graphene oxide/polyurethane finish(GO/WPU)and graphene/polyurethane finish(rGO/WPU)are prepared using the modified Hummers method.The polyester-cotton-based and cotton-based fabrics are treated by dip-padding process.The radiation protection function,strength and air permeability of the fabrics are tested.The best process parameters are optimized by comparing and analyzing the trend of each index.The results show that the electromagnetic radiation shielding effect of graphene oxide fabric is better than that of graphene fabric.The electromagnetic shielding effect of polyester-cottonbased graphene fabric of 10 mg/mL is the best,which can reach 25.3 dB.
