<p>Microencapsulated phase change material (MEPCM) with dodecanol as the core material and urea-formaldehyde resin as the wall material was prepared using an in situ polymerization approach in this work. The effects of the ratio of core to wall material (0.5–1.5), the content of OP-100 (0.1–0.3 wt%), and the content of resorcin (1–3 wt%) on the mass content of dodecanol in the final product were evaluated by a complete 23 central composite rotatable design. The products obtained were characterized using a scanning electronic microscope (SEM), differential scanning calorimeter (DSC), and thermogravimetric analyzer (TGA). The MEPCMs obtained were spherical microparticles with a rough surface and an average diameter of about 1 µm. The content of dodecanol in the MEPCMs obtained is up to 64.7 wt%. The results from the TGA show that the microcapsules prepared have excellent thermal stability with a two-stage decomposition profile at considerably high temperatures (above 80°C). Finally, the optimum conditions were a ratio of core to wall material 1.5, the content of OP-100 0.24 wt%, and the content of resorcin 2 wt%.</p>
