Popis: We present a new approach for designing thermal shielding materials using two-dimensional oxide nanosheets. Our approach uses hetero-assembly design [(Ti _0.87 O _2 ) _m (Cs _2.7 W _11 O _35− _d ) _20 ( m = 0, 5, 10)] by overlaying high refractive index ( n ) Ti _0.87 O _2 nanosheets with transparent conducting Cs _2.7 W _11 O _35− _d nanosheets. Through proper design of the thickness of high- n Ti _0.87 O _2 layers, we achieved the optimum thermal shielding properties with a high NIR reflectance (>46%), a high visible transparency (>76%) and a neutral color in an ultrathin form (
