The invention discloses a kind of fibrous composites and preparation method for robot electronic skin.The fibrous composite is made by following steps: a, by pyromellitic acid anhydride and 4, and 4 '-diphenyldiamines are added in N-Methyl pyrrolidone, and hollow polyimide fiber is made in wet spinning and hot-stretch after polycondensation reaction；B, tin gallium liquid metal is filled into full hollow polyimide fiber；C, being placed in room temperature environment solidifies tin gallium liquid metal, and the fibrous composite for electronic skin is made.The method has the advantages that the present invention uses the fibrous material and filling liquid metal of hollow structure, good draftability when using tin gallium liquid metal excellent electric conductivity and solid-state, gained fibrous composite has high draftability and high conductivity, has broad application prospects in fields such as flexible wearable equipment, flexible electronic skin, intelligent robots. |
