Preparation method of stretchable conductive fiber with low resistance change

The invention discloses a preparation method of a stretchable conductive fiber with low resistance change. According to the method, polydimethylsiloxane is added dropwise to the surface of the water,heat treatment is performed, and a polydimethylsiloxane film is stripped off from the surface of the water to prepare the polydimethylsiloxane film; a metal evaporator is utilized, and a metal film isvapor-deposited on the polydimethylsiloxane film and is taken as a conductive layer; the polydimethylsiloxane film loaded with the metal film is laid on a substrate and curled to prepare the conductive fiber. The method is advantaged in that the conductive fiber is stretchable and has low resistance change, the preparation method is simple, the preparation condition is mild, and the method has far-reaching significance for further development and promotion of flexible electrodes and flexible electronics. 本发明公开的种可拉伸、低电阻变化的导电纤维的制备方法包括以下步骤：将聚二甲基硅氧烷滴加到水面上，加热处理，然后从水的表面剥离出聚二甲基硅氧烷薄膜，从而制备出聚二甲基硅氧烷薄膜；用金属蒸镀仪在所述聚二甲基硅氧烷薄膜上蒸镀金属膜，作为
