Research Progress on Intelligent Solar Shading Materials Based on Materials with Varying Reversibly Transmittance with Temperature

介绍了温致透光率可逆变化材料及其作为智能遮阳材料的研究进展。温致透光率可逆变化的智能遮阳材料可以根据环境温度变化,自动改变透光率,实现被动式遮阳。温致透光率变化材料根据转变机理分为相变体系、相分离体系和溶质粒径变化体系。一种基于纤维素延伸物的水凝胶温致透光率可逆变化材料研制的智能遮阳系统在与电致变色材料结合之后还可以实现主动式遮阳和被动式遮阳的统一。

The research progress of intelligent solar shading materials based on materials with varying rever sibly transmittance with temperature is presented. The transmittance of such materials can be adjusted by themselves by the temperature of circumstance, and are suitable for application in passive shading solar radiation. The materials can be divided into phase separation system, phase transition system and size of solute particle switching system ac cording to the switching mechanism. Intelligent solar shading systems based on cellulose derivative hydrogel, can be combined with electrochromic materials to achieve the active and passive solar shading at the same time.
