Wall Latex Paint with Graphene Oxide Incorporation

Abstract

Graphene has stood out in several areas of research. The objective of the present work was an unprecedented study in the production of a commercial wall latex paint with graphene oxide incorporation. The developed paint was assessed by performance tests according to the Brazilian standards, and the characterization was performed using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared (FTIR), thermogravimetric analysis (TGA), and contact angle analysis. The results indicated that GO addition led to a better dispersion of the paint compound mixture even at very low concentrations (1% and 2%). For the dry and wet paint coverage performance tests, the results were superior, 2% and 9%, respectively, when compared with the paint without GO addition. All performance tests were in accordance with the requirements of the Brazilian standards. Thus, it was concluded that GO-containing paint could be a promising building material to be used as a paint additive obtaining superior properties.
