UV light, temperature and humidity are suspected to cause changes in nanocomposites properties to a point that could represent a liability, not only reducing the useful lifetime of components but also compromising the systems that contain them and posing safety and health risks. Inclusion of diverse fillers is believed to enhance the thermal-mechanical-chemical stability of the nanocomposites; however, detailed analyses that substantiate and quantify its effects are very limited. To address this need, we fabricated epoxy based nanocomposites containing diverse fillers and exposed them to the weathering factors mentioned above. The study focused on epoxy composites fabricated with: CNT, silica, nickel and Ni/NiO nanoparticles. The first because they are commonly used, the latter to determine the effects of using materials with different polymer-filler interfaces and electrical conductivity. The corrosion effects in metal sheets/nanocomposite couples were studied using a salt fog and accelerated weather chambers and are included in the analysis.
