▎ 摘　　要

NOVELTY - The method involves (S1) boiling the silk cocoons with sodium bicarbonate for 30 minutes, dissolving in lithium bromide aqueous solution, stirred continuously for 1 hour, and then dialyzing in deionized water for 3 days to obtain the silk precursor to be modified, (S2) heating and stirring the carbon nanomaterials in the treating agent to obtain a uniformly dispersed solution of modified graphene or carbon nanotubes, (S3) mixing the modified graphene or carbon nanotube solution and the silk precursor to be modified, and then ultrasonically dispersing to obtain a graphene or carbon nanotube modified silk fiber mixed solution, and (S4) adding 0.1-1% copper chloride and nickel chloride to the obtained graphene or carbon nanotube-modified silk fiber solution, stirring the sodium hydroxide aqueous solution was stirred into the above solution, reacting in a heating device at 60 °C for 6 hours, dialyzing with deionized water for 1 day, and placing at room temperature. USE - Method for in-setu preparing self-heating flexible wear-resistant nano fiber material, which is used for constructing electronic skin. Can also be used in energy, artificial muscle, neuroscience, nano-science and manufacturing, 3D printing, optical fiber material, medical healthcare. ADVANTAGE - The method enables to prepare self-heating flexible wear-resistant nano-fiber material, which has excellent performance of self heating and ventilation property, and exhibits excellent spontaneous thermal performance and temperature and humidity sensing function in the smart wear-resistant sensing system.
