智能遮阳材料的应用性能初探
Preliminary Research on Application Properties of Intelligent Solar Protection Materials
摘要
Abstract
The intelligent solar protection materials can be made out by using soluble polymer and inorganic salts. The switching temperatures, transmittance, sensitivity and hysteresis of these materials can be changed by adjusting the proportion of soluble polymer and inorganic salts. Based on this, the optimal compositions were optimized. The results of daytime insolation indicate that the maximum temperature difference of the insolation device reaches 30 ℃ when the intelligent solar protection material is transparent. However, when the material changes to opaque, the maximum temperature difference is 10 ℃ lower than that of the transparent state, which can make the over-hot phenomenon above the switching temperature diminished. No problems are recognized in 1 000 cycles of tests from - 10 ℃ to 50 ℃ . The freezing point of these materials are lower than - 10 ℃. Besides, these materials can keep 5 years light durability and keep steady white and opaque state for longer than 1 year above the switching temperature.关键词
