氧化石墨烯对蚕丝的紫外线防护整理

UV protective finishing of silk fabrics with graphene oxide

摘要:

采用氧化石墨烯（GO）对蚕丝织物进行紫外线防护整理，并对浸渍吸附GO的蚕丝织物进行还原得到还原氧化石墨烯（RGO）整理蚕丝织物。研究了GO和RGO整理蚕丝织物的紫外线防护性能，并测试了RGO整理蚕丝织物的抗紫外耐久性。采用扫描电子显微镜（SEM）和拉曼光谱（Raman）对RGO整理蚕丝织物进行了表征。研究结果表明，GO对蚕丝织物进行浸渍-还原法紫外线防护整理的最佳工艺为GO 0.5g/L，还原剂保险粉1 g/L，还原温度75℃，还原时间5min，整理蚕丝织物的UPF值在40以上，获得优异的紫外线防护效果；相同条件下RGO整理蚕丝织物的紫外线防护性能优于GO整理蚕丝织物，且RGO整理蚕丝织物经多次水洗后抗紫外性能降低很小，说明RGO整理蚕丝织物的耐久性好；由SEM和Raman表征也证实了RGO在蚕丝织物表面的沉积。

Abstract:

Graphene oxide (GO) was applied to UV protective finishing of silk fabrics. And the GO absorbed on the surface of silk fabrics was reduction to reduced graphene oxide (RGO). The UV protective performance of GO and RGO finished silk fabrics was researched. And the UV protective durability of RGO finished silk fabrics was tested. The silk samples were characterized by SEM and Raman spectra. The results showed that the optimal UV protective finishing process, GO 0.5 g/L, sodium hydrosulfite 1 g/L, reduced at 75 ℃ for 5 min, the UPF of finished silk fabrics was above 40, obtained excellent UV protection effect. The anti-UV performance of RGO finished silk fabric changed little after several times of washing, indicating that the durability of RGO finished silk fabric is excellent. The SEM and Raman results showed that the GO was deposition on the surface of silk fabrics.
