RGO/Ag交替层层组装纯棉导电纱的制备及其性能

Preparation of Electrically Conducting Cotton Yarn by Layer-by-Layer Assembly with RGO/Ag and Its Property

为了制备RGO/Ag交替层层组装纯棉导电纱,按组装顺序设计了6种方案,观察纱线表观结构并分析纱线TG、静态电阻、压力电阻及耐洗电阻。结果显示,外层包裹RGO的五层RGO/Ag交替组装所形成的导电纱线表面褶皱多,Ag层在石墨烯片层间镶嵌好,所形成导电纱线导电性能好;受压时,组装纱线伸长电阻增大但石墨烯间的层间距减小,使得石墨烯与纱线的界面结合好而所形成的导电纱线电阻减小.

In order to prepare alternately assembled conductive cotton yarn,six schemes are designed,and the apparent structures of the yarn are observed and the conductive yarn TG,static resistance,pressure resistance and washing resistance are analyzed.The results show that there are more folds on the surface of the conductive yarn consisting of five alternative layers of RGO and Ag with an RGO outer wrapping,and the Ag layer is well inlaid between the graphene layers,so the conductive yarn has good electrical conductivity.The conductive yarn elongates under stress and its resistance increases,but the interlayer spacing between graphene decreases,making the interface boundary combination excellent and the resistance decrease.
