The invention relates to the technical field of polyolefin dielectric material synthesis, and discloses a preparation method of a POSS-bis (trifluoromethyl) biphenyl-TiO2 modified polyolefin composite material, which comprises the following steps: carrying out Michael addition reaction on a phenyl functional group of a PDA-TiO2 hybrid dielectric monomer and an amino functional group of 2, 2-bis (trifluoromethyl) diaminobiphenyl to obtain the POSS-bis (trifluoromethyl) biphenyl-TiO2 modified polyolefin composite material. The amino-terminated di (trifluoromethyl) biphenyl-TiO2 hybrid dielectric monomer is obtained; the preparation method comprises the following steps: carrying out substitution reaction on an amino functional group of an amino-terminated di (trifluoromethyl) biphenyl-TiO2 hybrid dielectric monomer and a chlorine functional group of 3-chloropropyl POSS (Polyhedral Oligomeric Silsesquioxane) to obtain a POSS-di (trifluoromethyl) biphenyl-TiO2 hybrid dielectric monomer; the POSS-bis (trifluorometh
