| titleOfInvention | High-conductivity carbon nanotube grafted polyurethane composite material and preparation method thereof |
| abstract | The invention relates to the technical field of polyurethane materials, and discloses a high-conductivity carbon nano tube grafted polyurethane composite material, wherein an acyl chloride group and hydroxyl of propargyl alcohol are subjected to esterification reaction to obtain an alkynyl carbon nano tube, 2, 2-bis (azidomethyl) propane-1, 3-diol is used as a diol micromolecule chain extender, the diol micromolecule chain extender participates in the polyurethane polymerization process to obtain polyurethane containing an azido group, the azido group of the polyurethane and the alkynyl of the carbon nano tube are subjected to high-efficiency click reaction to obtain the carbon nano tube grafted polyurethane composite material, a chemical bond covalent grafting method improves the interface interaction and compatibility of the carbon nano tube and the polyurethane, reduces the agglomeration phenomenon of the carbon nano tube, the highly dispersed carbon nano tube forms a three-dimensional conductive network in the polyurethane, enhances the conductivity and the electric conductivity of the material, and the carbon nano tube with excellent mechanical property is used as a crosslinking center, the tensile strength of the polyurethane is obviously improved. |
