氧化石墨烯对织物的浸渍整理及在织物上的还原工艺

Impregnation finishing of fabrics with Graphite oxide and its reduction process on fabrics

近年来,随着纺织科技的不断发展,功能织物已经成为纺织品领域的研究热点。石墨烯以其优异的电学、热学以及抗紫外等性能,在制备功能织物方面发挥着重要作用。通过自制的氧化石墨烯对涤纶织物进行整理,并通过还原法将织物上的氧化石墨烯还原为石墨烯。通过改变氧化石墨烯的用量、焙烘温度、整理液pH探讨优化的后整理工艺,分析还原剂用量、还原时间对氧化石墨烯整理涤纶织物导电性能和抗紫外性能的影响。结果表明,通过还原后,石墨烯涤纶织物平均体积比电阻最好可以达到0.409 MΩ·cm,接近于传统水合肼还原工艺(0.383 MΩ·cm),且整理后的织物表现出优异的抗紫外性能,UPF值最高达到426.23,远远高于未整理的涤纶织物(UPF=7.25),此方法为实现石墨烯基织物的工业化提供了研究基础。

In recent years,with the continuous development of textile technology,functional fabrics have become a research hotspot in the field of textiles.The Graphene plays an important role in the preparation of functional fabrics due to its excellent electrical,thermal,and UV resistance properties.The polyester fabric was treated with self-made Graphite oxide,and Graphite oxide on the fabric was reduced to Graphene by re⁃duction method.By changing the amount of Graphite oxide,and baking temperature and pH value of finishing solution,the optimized post finishing process was discussed.The effects of the amount of reducing agent and reducing time on the conductivity and UV resistance of polyester fabric treated with Graphite oxide were ana⁃lyzed.In addition,the effects of the amount of reducing agent,reduction time on the conductivity and UV re⁃sistance of polyester fabric treated with Graphite oxide were analyzed.The results showed that the average volume specific resistance of Graphene-polyester fabric could reach 0.409 MΩ·cm after reduction,which was close to 0.383 MΩ·cm achieved by the traditional hydrazine hydrate reduction process,and the treated fabric exhibited excellent UV resistance,with UPF value up to 426.23,which was much higher than the untreated polyester fabric(UPF=7.25).This method provides a research basis for the industrialization of graphene based fabrics.
