Abstract

The invention discloses a polypyrrole / nanometer platinum composite conductive fiber and a preparation method thereof. The method comprises the following steps of: performing treatment such as proper cleaning and the like on a fiber, soaking in an oxidant solution for 10 to 30 minutes, air-drying at room temperature or drying, putting the treated fiber into a sealed container filled with pyrrole steam, reacting at the temperature of between 0 and 30 DEG C for 5 to 30 minutes, respectively washing by using ethanol and deionized water, and air-drying or drying to obtain a conductive fiber A; and soaking the conductive fiber A in a chloroplatinic acid (H2PtCl6.6H2O) aqueous solution at the concentration of 0.1 to 1.0mol / L for 0.5 to 2 hours, dipping in pyrrole aqueous solution at the concentration of 0.01 to 0.1mol / L, reacting at room temperature for 6 to 10 hours, respectively washing by using ethanol and deionized water, and air-drying or drying to obtain the polypyrrole / nanometer platinum composite conductive fiber. The conductive fiber can be directly used for weaving and also can be blended with a common fiber in a ratio of 1:10-100 to prepare a fabric with an antistatic function and an electromagnetic screen function. The specific resistance of the polypyrrole / nanometer platinum composite conductive fiber is 103 to 107 omega.cm; and the polypyrrole / nanometer platinum composite conductive fiber has the antistatic function and the electromagnetic screen function.

technical field [0001] The invention relates to a conductive fiber and its preparation method and application, in particular to a polypyrrole / nano-platinum composite conductive fiber and its preparation method and application. Background technique [0002] Textiles are prone to static electricity due to friction and induction during production, processing and use, while conventional fiber materials have a resistivity of 10 10 Above Ω·cm, the generated charge is not easy to escape. The accumulation of electrostatic charge will not only affect the comfort of clothing during wearing, but also affect human health, and cause damage to electronic components; electrostatic discharge can cause accidental explosion of explosives and electrical explosives, and the electromagnetic waves generated by electrostatic discharge Radiation will cause electromagnetic interference to various electronic equipment and information systems. [0003] With the rapid development of electronic techno...
