Transparent wood containing CsxWO3 nanoparticles for heat-shielding window applications

Abstract

Cs_xWO₃ nanoparticles were dispersed in prepolymerized methyl methacrylate (PMMA) and filled in nanopores of delignified wood to prepare transparent wood. The wood-based composite showed excellent near-infrared (NIR, ranging from 780 to 2500 nm) shielding ability and high visible light transparency. The Cs_xWO₃/transparent wood also showed excellent mechanical properties with a fracture strength up to 59.8 MPa and modulus up to 2.72 GPa. Cs_xWO₃/transparent wood is expected to serve as a potential material for smart-window applications.
