Abstract:

<p>Epoxy resins are employed a coating materials in aircraft as well as marine applications owing to its outstanding mechanical and chemical resistance. Epoxy composites are also effective in constructing body parts of aircraft and marine vehicles. But due to degradation by water, epoxy nanocomposites have less durability. Hence to enhance the water repelling ability or decrease the uptake of water of epoxy composites it is advisable to incorporate nanofillers. Graphene is an excellent nanofiller for toughening epoxy due to its mechanical, thermal and electrical properties and hence it is a very adaptable filler to improve many properties of epoxy like mechanical, thermal and electrical properties. Present work focuses on the enhancement of barrier properties especially on moisture resistance of epoxy graphene oxide nanocomposites after curing using Diaminodiphenyl methane. In this specific study moisture uptake of epoxy and epoxy nanocomposites having different compositions were analyzed at different temperature ranges like room temperature 30, 50°C and 70°C taking water as a solvent for a time period of 15 days.</p>
