“…In buildings, energy savings of 20% can be made through smart windows due to reduced lighting, heating and cooling costs [ 2 ]. Currently, various technologies are known to fabricate such windows including electrochromic (EC) [ 3 , 4 , 5 ], suspended particle electrophoresis [ 6 , 7 ], polymer dispersed liquid crystals (PDLC) [ 8 , 9 , 10 ], polymer stabilized liquid crystals (PSLC) [ 11 , 12 , 13 , 14 , 15 , 16 ] and polymer stabilized cholesteric liquid crystals (PSCLC) [ 17 , 18 , 19 , 20 , 21 , 22 ]. Among them, electrically tunable infrared (IR) reflecting/transmitting windows based on PSCLC, which can selectively reflect different fractions of infrared radiation on demand without affecting the transmittance in the visible region, appear to be very attractive [ 21 , 22 ].…”
