Research on properties of phenolic resin/montmorillonite nanocomposites synthesized under microwave irradiation

The properties of phenolic resin/montmorillonite nanocomposites synthesized under microwave irradiation were researched,and the results indicated that the properties of nanocomposites were improved markedly.The flow ability of nanocomposites was markedly increased when the montmorillonite content was 2%by weight for the montmorillonite has exfoliation structure,and the flow ability decreased if the montmorillonite content was further increased.The mechanical properties of nanocomposites such as tensile strength,tensile modulus and elongation at fracture were also improved with adding montmorillonite.And the mechanical properties decreased when the montmorillonite was in aggregate for excess of its content.The thermal stability of nanocomposites was enhanced and decomposition temperatures and residual carbon weight were raised in different extent,because the montmorillonite exhibited a protection function for resins at high temperature.
