Emplacement of screen-printed graphene oxide coating for building thermal comfort discernment

Abstract

This study demonstrates the development of flexible graphene oxide coatings (GOCs) by the screen-printed technique and further its implementation as a thermal absorber for buildings’ thermal comfort purpose. The basic concept consists the integration of the GOC as a flat absorber on the top of a low iron glass or aluminium-based substrate (5 × 5 cm2) connecting through a phase change material channel in contact with direct sun exposure. The function of GOC as an outdoor cover of the prototype chamber is to maintain the high indoor temperature while the outdoor temperature is low. Using the GOC, it has been observed that the indoor temperature (at the substrate) of the prototype chamber always remains higher as compared to the outdoor temperature (at the GOC) as measured under 1 SUN 1.5 AM condition. The temperature difference between outdoor and indoor exterior surface significantly increases during the light exposure time, whereas the difference drastically approaches to zero during the cooling period. The variation of different crucial environmental factors such as high temperature, moisture, flexibility and water resistivity has been investigated on the developed GOCs to understand the stability of the coating further.

A Review on Heavy Metal Ions and Containing Dyes Removal Through Graphene Oxide‐Based Adsorption Strategies for Textile Wastewater Treatment

“…The CVD method is useful for a pure and single graphene production layer. The graphene layer defects can be controlled; moreover, the oxidation‐reduction method is the most straightforward and low‐cost method to produce graphene and their derivatives [162,163,164] . The process creates high‐quality graphene, but the graphene is often damaged when it comes time to detach it from its substrate.…”

Synergistic Effect of Paraffin-Incorporated In2O3/ZnO Multifold Smart Glazing Composite for the Self-Cleaning and Energy-Saving Built Environment

“…A Pico TC-08 (Pico Technology) data logger was used to measure the continuous temperatures. 30 Besides, a FLIR T425 camera was used to capture the IR images of the IZPC-5 film from a distance of 10 mm. Six IZPC film samples were investigated to measure their respective transmittance spectra.…”
