Thermochromic composite material for intelligent window
The invention discloses a thermochromic composite material for an intelligent window and a preparation method of the thermochromic composite material, water-soluble CMC is introduced into an aqueous dispersion of PNIPAM or HPC, and the phase change temperature of PNIPAM or HPC is reduced by using the hydrophilicity of CMC; the number of scattering centers of PNIPAM or HPC is increased by utilizing a molecular skeleton formed by CMC in water, the solar energy modulation capability is improved, and the thermal stability of the thermochromic material is enhanced. The method is simple, effective and wide in application prospect.
本发明公开了一种用于智能窗的热致变色复合材料及其制备方法，把水溶性的CMC引入到PNIPAM或HPC的水分散液中，利用CMC的亲水性，降低PNIPAM或HPC的相变温度；利用CMC在水中形成的分子骨架，增加PNIPAM或HPC的散射中心数量，提升太阳能调制能力，增强热致变色材料的热稳定性。方法简单有效，应用前景广阔。
