Abstract | This invention relates to a method for preparing opal/polyurethane solid-solid phase transition energy-storage material. The molecular structure of the material is shown in formula I, where, poly (ethylene glycol) is the soft segment, while aliphatic and aromatic isocyanate, and trihydroxyl substance are the hard segments. The method comprises: (1) preparing prepolymer of poly (ethylene glycol) with terminal groups activated by isocyanate groups; (2) preparing opal/polyurethane solid-solid phase transition energy-storage material. The method has such advantages as low raw material cost, no toxicity of the product, and simple process. The addition of natural nanomaterial (opal) can increase the phase transition enthalpy value and heat response rate of the material, and can reduce the cost. The opal/polyurethane solid-solid phase transition energy-storage material can effectively save energy, and has potential applications in such fields as agriculture, energy resources, textile, construction and electronics. |
