Exploration of physical and optical properties of ZnO nanopowders filled with polydimethylsiloxane (PDMS) for radiation shielding applications. Simulation and theoretical study

Flexible and multifunctional composite films based on rare earth phosphors as broadband thermal emitters for high-performance passive radiative cooling

“…The absorption peaks at wave-numbers 788.85/787.72 cm À1 and 1257.26/ 1257.35 cm À1 belong to the -CH 3 vibration peak and the Si-C stretching peak of the Si-CH 3 functional group. 26,39,40 The absorption peaks at wave-numbers 1010.63/1010.17 cm À1 correspond to the anti-symmetric contraction vibration peaks of Si-O-Si, and these all can correspond to the structure of PDMS (Fig. S4a and b, ESI †).…”

“…9,16,[23][24][25] Polymer films are often used as radiation cooling materials because of their high radiation characteristics in the mid-infrared band. 26 By mixing polymer and nanoparticle materials, films with high reflectivity and high emissivity can be produced. 22 In order to enhance the daytime cooling performance, many studies have introduced a selective radiator with high radiation in the 8-13 mm band.…”
