Thermochromic Hydrogels for Synergistic Mechno-Optical Properties

The figures collectively illustrate the multifunctional performance of PDH hydrogels: the Transmittance–Composition and Transmittance–Temperature plots highlight the optical tunability, showing how the hydrogel’s transparency varies with composition and temperature. The Stress–Strain Curve demonstrates the mechanical robustness and elasticity, while the Transition Temperature plot reflects the hydrogel’s thermoresponsive behavior. Additional figures, including Effect of Thickness, Transmittance Comparison Plot, Comparison of Temperature Variation, Daily Energy Savings, and Mass Change, further emphasize the hydrogel’s performance in light modulation, thermal regulation, energy-saving potential, and stability under environmental changes.
