石墨烯银层层组装纯棉导电纱及性能分析

Manufacture of Graphene Silver Layer-by-layer Assembled Pure Cotton Conductive Yarn and Its Property Analyses

探讨石墨烯银层层组装纯棉导电纱的制备工艺及性能。以纯棉纱线为原料,使用导电性能极佳的石墨烯和纳米银采用层层复合组装技术,利用多层浸泡的方法使石墨烯和纳米银附着在纯棉纱线上。结果表明:三层石墨烯附着在纱线上形成许多沟槽,加纳米银微粒有利于电子在纱线上传递,因此三层石墨烯与银组装而成的纱线阻值明显降低且稳定在一个范围内。认为:制得的纯棉导电纱线因石墨烯和纳米银的组装而具有优良的导电性能、压电性能和耐洗性能。

The manufacture process and properties of graphene silver layer-by-layer assembled pure cotton conductive yarn were discussed.Pure cotton yarn was used as raw material.Graphene and nano-silver whose conductivities were excellent were adopted.Layer-by-layer assembly technology and the method of multilayer immersion were used so that graphene and nano-silver were attached to pure cotton yarn.The test results showed that a lot of grooves were formed when three layers of graphene was attached to the yarn.The addition of nano-silver particles was beneficial to electric delivery on the yarn.Therefore,the resistance value of the yarn attached by three layers graphene and silver was greatly reduced and stable within a range.It is considered that the pure cotton conductive yarn has excellent conductivity property,piezoelectric property and washability due to the assembling with graphene and nano-silver.
