Abstract
We demonstrated a simple solution synthesis method of ZnO nanoparticles to explorer the probability of controlling diameter and shape by the synthesis conditions. The optimized synthesis condition of ZnO nanoparticles was found for application of NIR scatterer. The ZnO nanoparticles with an average diameter of 370 nm, which is suitable diameter for NIR scatterer, were observed. The diameter of observed 76% nanoparticles was under 500 nm. The synthesized ZnO nanoparticles were hybridized with transparent amorphous polymers (PMMA) for the purpose of film applications as NIR scatterer. The optical properties of ZnO-polymer materials were examined in the UV-VIS and FT-IR. We confirmed that the transmittance of ZnO-polymer (containing 10 wt% of ZnO nanoparticles) in NIR region is clearly reduced. To achieve effective NIR scattering film, ZnO-polymer ratio should be optimized
