| titleOfInvention | Flexible, high enthalpy polymer solid-solid phase change material and its preparation method and application |
| abstract | The invention discloses a preparation method of a polymer solid-solid phase change material, comprising: performing a click polymerization reaction on a ternary alkynyl compound, polyethylene glycol, and an organic base catalyst in an organic solvent to obtain the polymer Solid-solid phase change material; in the click polymerization reaction system, AIE photothermal molecules can also be included; the method of the present invention utilizes a one-step hydroxyl-alkyne click polymerization reaction, and the obtained polymer solid-solid phase change material has good mechanical properties and is It can maintain a solid state without leakage at the phase transition temperature. It has a high enthalpy value. The crystallization enthalpy is greater than 94J/g, and the melting enthalpy is greater than 105J/g. It can realize shape memory by changing the temperature. The doping of AIE photothermal molecules can make it charge heat under sunlight, store energy by directly absorbing heat or self-heating under light. The polymer solid-solid phase change material of the present invention has broad application prospects in the fields of intelligent driving and/or thermal management. |
