Infrared(IR),the electromagnetic wave with wavelength longer than 700 nm,particularly,accounts near half of the solar irradiation and most of the electromagnetic radiation by matters at room temperature.Developing the ability to block or reflect IR is essential for broad civilian and military applications.Herein,we will report some of our recent progresses on the soft polymeric infrared reflective materials.Utilizing the strategy of polymerization-induced Liquid Crystal phase transition(from cholesteric phase to smectic-like short-range ordering structure),we have synthesized a novel class of liquid-crystal-based polymers that are transparent to visible light and highly reflective for IR from 0.7 to 14 μm in wavelength.The polymeric infrared reflective thin films with ultra-broad-bandwidth can be fabricated using a simple and low-cost wet-chemistry process,which is of considerable industrial benefits.Moreover,the related applications in energy conservation and infrared-stealth technology are also full of great significance.
