Similar to the thermoplastic composites, modified nanofillers like nanoclays, silica and POSS are also used in as reinforcement to improve the properties of the composite.
A cost-effective way in exfoliating clay in epoxy resin system is developed. Due to the uniformity in dispersion and the strongly adhesion between the clay and epoxy, composites with better thermal stability and mechanical property are obtained when compared with its conventional counterparts.
The clay are exfoliated and silanised. The silanised clay are then transferred to epoxy matrix and compressed and cured into laminates.

Besides clay, POSS is also used as nanofillers in polymeric composites. This bio-inspired nanofiller with structural design in molecular level and synergism of each molecular segment. This system is tunable, possesses uniform filler size and has good dispersion of the filler in the polymer matrix.
