High-Efficiency Responsive Smart Windows Fabricated by Carbon Nanotubes Modified by Liquid Crystalline Polymers

Smart windows can dynamically and adaptively adjust the light transmittance in non-energy or low-energy ways to maintain a comfortable ambient temperature, which are conducive efficient use of energy. This work proposes liquid crystal (LC) smart window with highly near-infrared (NIR) response using carbon nanotubes grafted by biphenyl LC polymer brush (CNT-PDB) as orientation layer. The resultant CNT-PDB provide vertical molecules initial transparency. At same time, shows rapid NIR light, quickly prevent sunlight from entering room. Different common doping systems, this method avoids problem poor compatibility between host photothermal conversion materials, is beneficial for improving durability device.
