A STUDY ON HEAT INSULATIVE NANOCOATINGS TO ENHANCE THERMAL REDUCTION ON POLYMER-GLASS SUBSTRATE FOR GREEN BUILDING AND INDUSTRY APPLICATION

Abstract

Nanotechnology has greatly impacted the building and construction industry. With the application of this technology, new materials can be used for PPE & future building applications. In this paper, 16 nanoparticles are experimented on to find out the best heat reduction nanoparticles to be used as coating for PPE application. These 16 nanoparticles had been divided into 2 categories, metal and non-metal oxide. The result had been presented in dispersion, transmittance, and thermal result. In the dispersion and transmittance result, WO3 and CuO had shown promising result in VR and NIR. As for the thermal result, Al2O3 had shown better temperature reduction result than WO3 and CuO. It was found that Al2O3 had no transmittance reduction in the VR, but it had transmittance reduction in the NIR. Comparing with the transmittance and thermal result of Al2O3 with WO3 and CuO, it was found that in VR, Al2O3 is reflecting visible light which in turn no transmittance reduction. As for the NIR, Al2O3 had low transmittance reduction than WO3 and CuO as Al2O3 is reflecting the heat. It was due to Al2O3 is a reflectance material that it had better temperature reduction than WO3 and CuO. In the conclusion of the discussion, Al2O3 is proposed to use for heat reduction coating and suggestions of where such coating can be used for building industry application was highlighted.
