“…1,2017 In recent years, polymer/clay nanocomposites have attracted great attention in both academic and industrial researches, due to their synergistic advanced properties at realtively low nanoclay loadings (up to 5 wt%). [7][8][9][10][11][12] The typical enhanced properties include tensile strength, heat deflection temperature, barrier properties, and so on. [13][14][15] Because of these good properties and low price, industrial applications of nanoclay also found great attraction nowadays.…”

This study aimed to investigate the effect of organoclay concentration variation (1-5 wt%) on the weathering resistance of epoxy resin in terms of the strength, modulus and weight changes of the specimens after exposure to accelerated weathering conditions. Transmission electron microscopy (TEM) revealed an exfoliated and good dispersed nanofiller structure throughout the matrix up to 3 wt% loading. The tensile strength, modulus, and weight of the samples decreased after combined UV radiation and condensation, with much less extent for the nanocomposites than neat epoxy indicating that the presence of organoclay led to dominant enhancement in mechanical properties endurance of epoxy resin to environmental degradation. Nanocomposites also displayed much lower weight loss as compared to the unfilled epoxy after being subjected to the accelerated weathering by either temperature-humidity or by combined UV radiation and condensation.
