Abstract

The invention relates to a continuous preparation method and application of high-elasticity electric-conductive fiber years. The electric-conductive nano-fiber yarns are composed of carbon nano tubes and TPU elastic nano-fiber yarns. According to the invention, an electrostatic spinning device is applied at first, and water bath is used for collection, so the continuous TPU elastic nano-fiber yarns could be prepared. For the purpose of making the nano-fiber yarns electrical-conductive, the fiber yarns are made to absorb carboxylation MWNTs and then absorb unmodified SWNTs through ultrasonic absorption. Two types of carbon tubes could react with a substrate and could react with each other, so the continuous elastic nano-fiber yarns with high electric conductivity is prepared. The elastic yarns have higher electric conduction performance than fiber yarns prepared through separate absorption of the MWNTs and SWNTs. The yarns are characterized by high elasticity, high electric conductivity, stretchability, linear knitting performance and so forth; and the yarns have extensive potential application in wearable electronic devices and have bright application prospect in fields such as electromagnetic shielding, static resistance, sensors and flexible energy devices.
