[Abstract]:In recent years, single-walled carbon nanotubes and Polyaniline have attracted much attention due to their unique adsorptive properties. It is of practical significance to study the tensile composite conductive fabrics based on single-walled carbon nanotubes, Polyaniline and Laika fabrics for the development of new flexible electrodes and the broadening of their application fields. In this paper, the electrical and tensile properties of single walled carbon nanotube / Laika composite conductive fabric and single wall carbon nanotube / Polyaniline / Laika composite conductive fabric are analyzed and experimentally studied. Through surface modification and dispersion treatment of single-walled carbon nanotubes, composite conductive fabrics were prepared by high-temperature impregnation and drying method. Composite conductive fabric with good adhesion and stability. The mechanical and electrical properties of composite conductive fabric with different tensile strength were studied. The experimental results show that the single wall carbon nanotube / Laika composite conductive fabric has good tensile properties (initial square resistance is 65 惟 / sq., tensile strain can reach 35% and initial conductivity is maintained; single walled carbon nanotube / Polyaniline / Lecca composite) The conductive fabric has good conductivity (initial square resistance is 35 惟 / sqand tensile strain is kept in the range of 25%). The application of tensile composite conductive fabric in the field of flexible electronics is studied. The results show that the composite conductive fabric has good tensile properties as extensible conductor, and the composite conductive fabric is combined with tensile sensor. Good bonding and comfort between fabrics can better and more accurately measure the bending of human hand joints. The composite conductive fabric is simple in preparation and low in cost. It has great potential application value in the field of wearable devices in the future.
