Abstract:

In order to obtain high conductivity and stable strain sensing performance, conductive spandex/polyaniline composite fiber was prepared via in-situ polymerization followed by structure and properties analysis of the composite fiber. The spandex/polyaniline/polyurethane composite was prepared from composite conductive fiber and water-soluble polyurethane, and its strain sensing performance under different tensile conditions was studied. The results show that a dense layer of polyaniline is formed on the surface of spandex fiber, and its conductivity reaches 0.626 S/cm. The conductive polyaniline layer on the surface of spandex/polyaniline composite fiber is damaged by the reciprocating stretching, which affect the repeatability of the strain sensing performance. The protection of polyurethane improves the repeatability of the strain sensing property of the spandex/polyaniline/polyurethane composites. For example, under the condition of 100% strain, the ratio of resistance value and initial value of the composites after 10 times of stretching and stretching recovery decreases by about 66.7% and 50.0% compared with the conductive spandex/polyaniline composite fiber.
