To address the insufficient response performance of conventional temperature control coatings in complex temperature environments， a thermochromic reversible temperature control coating system was developed by using self-made thermochromic microcapsules with fillers. Solar reflectance testers， ultraviolet-visible near-infrared spectrometers，scanning electron microscopes，thermal conductivity testers，universal testing machine and other instruments were employed to systematically investigate the solar modulation performance，thermal conductivity，mechanical properties，adhesion，and durabilityof thermochromic coatings. The results indicated that hollow glass microspheres could enhancethe solar modulation performance of the thermochromic coatings by boosting the absorptionand dissipation of near-infrared light. After optimizing the formulation and film thickness，the solar modulation performance of the thermochromic composite coatings could reach 0. 326， the tensile strength could reach 6. 6 MPa，and the adhesion could reach 6. 5 MPa， demonstrating excellent comprehensive performance. Furthermore，after 200 temperature change cycles or 1 000 h artificial ultraviolet accelerated aging，the solar modulation performance degradation rate of the coating is less than 10% showing better cycle durability，making it suitable for long-termtemperature control of building structures in complex temperature environments.
