Using nano-TiO2 as the Pickering emulsion stabilizer and cross-linked polyurethane as the shell material, a composite protective structure was constructed to encapsulate core materials with phase-change and photochromic properties, thereby forming photochromic phase change microcapsules (TPT-MPCMs) with UV protection and thermal insulation.

The highly cross-linked shell formed by xylitol and isophorone diisocyanate effectively protected the core from thermal degradation up to 180 °C, while the nano-TiO2 shell surface allowed maintaining the UV responsiveness of microcapsules after exposure to intense UV irradiation for 5 h.
