1. a kind of β

  • type polypropylene conductive composite material, which is characterized in thatContaining weight percent be 1~10% modified carbonization bacteria cellulose nano material and weight percent be 90~99%Homopolypropylene;

    The modified carbonization bacteria cellulose nano material is prepared via a method which to obtain;

    S01. bacteria cellulose is placed in distilled water and is impregnated, then by squeezing, obtain bacteria cellulose film;

    S02. bacteria cellulose film is put into 1~5h of immersion in calcium acetate aqueous solution, the bacterium for the calcium acetate solution that is absorbed is fineTie up plain film BCa;

    The concentration of the calcium acetate aqueous solution is 0.1~0.2mol/L;

    S03. bacteria cellulose film BCa is placed in 1~3h of immersion in dehydrated alcohol, until calcium acetate precipitation is adsorbed on bacteria celluloseThe surface of film BCa obtains bacteria cellulose film BCb;

    S04., bacteria cellulose film BCb is handled to 1~5h under 800~1000 DEG C of oxygen free conditions, obtains CBCb compound;

    S05. CBCb compound is placed in 1~3h of immersion in the ethanol solution of pimelic acid, it is thin must to be modified carbonization for heating volatilization ethyl alcoholFungin nano material.
