PENA-BENITEZ, P.R. de la et al. Environmental assessment of water-based paints for building outdoor modified with graphene oxide. Superf. vacío [online]. 2016, vol.29, n.4, pp.105-111.  Epub 06-Nov-2020. ISSN 1665-3521.

In this study, we try to determinate the effects of aging on outdoor water-based paints with a reinforcement of graphene oxide by means of essays. Two essays are about accelerated aging by using UV light and hydrothermal chamber; and, the other essay is about using natural aging by direct exposure to atmosphere agents. Samples were prepared and put to three types of tests; lately, they were tested by colorimetric exam of their parameters of CIELab. The different behaviors of paints were assessed during the essays, determinating the degree of stability, depending on the degree of addition of graphene oxide.

Palabras llave : Graphene oxide; outdoor paints; aging tests; functional groups; yellowing.
