2.2.2. Preparation Process of PCMP
- Expanded perlite has been dried in a drying cabinet for 5 h, at first. Then, a certain quality of paraffin, expanded perlite and magnetic particles were put into a suction bottle, and then the vacuum pump was started, in order to keep the internal pressure of the suction bottle to be 0.5 MPa.
- 30 min later, the heating magnetic stirrer was opened with the heating temperature of 80 °C. Then, the inside pressure of suction flask was further evacuated to 0.01 MPa. 2 h later, the vacuum absorption process was finished.
- The vacuum pump was closed and, meanwhile, the piston of the flask was removed. The paraffin can be further absorbed into the micropores of expand perlite, especially the residual paraffin in the surface of expanded perlite, under the driving force which was generated from the pressure change (from 0.01 MPa to atmospheric pressure).
- 1 h later, the heating magnetic stirrer was closed, and then paraffin/expanded perlite in the suction flask were naturally cooled. Finally, the preparation of composite phase change material was accomplished, and the real composite phase change material can be seen in Figure 3a.
2.3. Preparation of BESP
- PCMP and styrene acrylic emulsion were mixed and stirred in the mass ratio of 8:1.
- When they were mixed well, they were put into the mold that has the retaining flanges.
- The mixture of PCMP and styrene acrylic emulsion were distributed evenly and pressed with the pressure of 4 MPa to maintain the compactness.
- After a time period of 12 h, the shape of BESP was stabilized.
- Finally, BESP was successfully prepared, and was fetched out from the disassembled mold.

3.5. Dynamic Thermal Performance Analysis
- The best proportions of paraffin and EP in PCMP were ascertained to be 52.5 wt % and 47.5 wt %, respectively, and no liquid paraffin oozed from PCMP in leakage tests, after applying a coating film on PCMP.
- The phase change temperature and latent heat of PCMP were measured to be 21.6 °C and 56.3 J/g, respectively, through DSC.
- There was no significant degradation of thermal properties for PCMP sample after repeating melting and freezing cycles 1000 times.
- A high-quality thermal performance, including small temperature fluctuation, large temperature lagging, and high thermal storage capacity for BESP, was confirmed in a dynamic temperature input test.
