Polymer nanocomposite

Polymer nanocomposites (PNC of English polymer nanocomposites ) consist of a polymer matrix are well dispersed in nanoparticles or nanofillers. The nanoparticles can have different forms (eg, platelets, fibers or spheroids ), but must lie at least in one dimension in the range of 1-50 nm. PNC belong to the multi-phase systems (MPS from engl. Multi - phase systems, including dry blends, composites and foams), which consume almost 95 % of the production of plastics. The preparation of such systems requires controlled mixing, stabilization of the dispersions produced and orientation of the disperse phase. The method used for this purpose are similar for all MPS.

The transition from micro -to nano- particles results in the change of the physical and chemical properties. Two of the major factors are an increase in the surface-to- volume ratio and the size of the particles. The increase in surface-to- volume ratio which increases as the particles become smaller, resulting in an increasing dominance of the surface atoms on the volume of atoms. This has implications for the interaction with other particles. In addition, since the surface of the nanoparticles increases, enhances interactions with other particles in the mixture, which strength, heat resistance, etc., increases and affects many other factors.
