摘要:采用氧化石墨烯(GO)对蚕丝织物进行了紫外线防护整理,再对浸渍吸附 GO 的蚕丝织物(蚕丝-GO)
进行还原得到了还原氧化石墨烯(RGO)整理蚕丝织物(蚕丝-RGO)。考察了蚕丝-GO 和蚕丝-RGO 的紫外线
防护性能,并测试了蚕丝-RGO 的抗紫外耐久性。采用 SEM 和拉曼光谱对蚕丝-RGO 进行了表征。结果表明,
蚕丝-RGO 最佳制备工艺为:GO 质量浓度为 0.5 g/L,还原剂保险粉质量浓度为 1 g/L,还原温度 75 ℃,还原时
间 5 min。在上述条件下,蚕丝-RGO 的 UPF 值为 44.99,具有优异的紫外线防护效果;相同条件下,蚕丝-RGO
的紫外线防护性能优于蚕丝-GO。经多次水洗后,蚕丝-RGO 抗紫外性能略微降低,其优异的耐久性归因于沉积
在蚕丝织物表面的 RGO 与蚕丝间的相互作用。

Abstract: Finishing of silk fabric with graphene oxide (GO) for UV protection was first carried out, and the
dipped and adsorbed GO silk fabric (silk-GO) was reduced to obtain reduced graphene oxide (RGO)
finishing silk fabric (silk-RGO). Next, the UV protection performance of silk-GO and silk-RGO was
investigated, while the UV protective durability of silk-RGO was also tested. Silk-RGO was characterized
by SEM and Raman spectrum. The results showed that the optimum conditions for UV protective finishing
process were as the following: GO mass concentration of 0.5 g/L, sodium hydrosulfite mass concentration
of 1 g/L, reduction temperature of 75 ℃, and time of 5 min. Under the above-mentioned conditions, silk-
RGO had excellent UV protection effect with a UPF value of 44.99. The UV protection performance of
silk-RGO, which almost remained unchanged even after several times of washing, was better than that of
silk-GO at the same conditions. The excellent durability of silk-RGO was attributed to the interaction
between the RGO deposited on the surface of the silk fabric and the silk.
