Synthesis method of fluorine-containing and quaternary amine acrylate functional monomer grafted composite biomass derivative

The invention discloses a synthesis method of a fluorine-containing and quaternary amine acrylate functional monomer grafted composite biomass derivative. The preparation method comprises the following steps: by taking a bagasse xylan/resveratrol compound as a raw material, selecting three functional mixed monomers, namely trifluoroethyl methacrylate as a fluorine-containing monomer emulsified by sucrose fatty acid ester, dimethylaminoethyl acrylate as a quaternary amine acrylate active monomer and 2-acrylamide-2-methylpropanesulfonic acid as a water-soluble monomer; the fluorine-containing quaternary amine acrylate functional monomer grafted composite biomass derivative with anti-cancer double activity is synthesized through free radical graft copolymerization and cross-linking of a cross-linking monomer N, N-methylene bisacrylamide by taking acrylic acid as a monomer, ammonium persulfate and sodium hydrogen sulfite as initiators. Meanwhile, the inhibition rates of the product to human liver cancer cells and
