Polymer nanocomposites (PNC) is a polymer or copolymer having dispersed in its nanoparticles. These may be of different shape
fibers, spheroids), but at least one dimension must be in the range of 1 to
50 nm. These PNC's belong to the category of multi-phase
systems (MPS, viz. Blends, composites,
and foams) that consume nearly 95% of plastics production. These systems require controlled mixing/compounding,
stabilization of the achieved dispersion, orientation of the dispersed phase, and the compounding strategies for all MPS,
including PNC, are similar.
