AI Technical Summary
Existing flexible phase change materials experience a decrease in toughness during the transition from winter to summer, leading to fractures. Furthermore, traditional materials cannot simultaneously meet the needs of summer cooling and winter heating, and lack self-healing capabilities and flexibility.
By controlling the stirring acceleration, pouring speed, and heating time, a bilayer thin film material containing paraffin, linear tri-block copolymer, vinylidene fluoride-co-hexafluoropropylene polymer powder, and carbon nanotubes was prepared, ensuring material uniformity and thermal efficiency, and achieving self-healing and full-spectrum adaptability.
It improves the toughness and durability of materials, has self-healing capabilities, can adapt to full-spectrum radiative cooling and photothermal conversion, and reduces performance degradation caused by temperature fluctuations.
