Nano materials & Structure

Polymers comprising particles at least one dimension in the nanosize range (1-100 nm)

This is a class of materials that have properties with significant commercial potential.

Polymer nanocomposites offer the possibility of developing new classes of materials with unique

structure- property relationships. These nanostructure-property relationships are the frontier in

nanocomposites.

Attractive features identified with nanocomposites are

· Efficient reinforcement without loss of ductility and even improvement in impact strength

· Excellent optical and altered electronic properties, heat stability, flame resistance, improved gas barrier properties, improved abrasion resistance, reduced shrinkage and residual stress.

Classification of nanomaterials

Three dimension

All the dimensions are in nanometer range eg. Nano silica

Two dimension

              Two dimensions are in nanometer range,eg.wiskers or carbon nanotubes

Two dimension

              One dimension is in the nanometer range, eg. Layered silicates or clays

Processing

Conventional processing ( mixing, shapping , and curing if required ) with apropreate quantity of nano materials and other aterials are followed . For better properties special technics such as Intercalation and exfoliation are utilized . These are two majour type of distribution of nano aterial in polyer chain

Applications

Automobile, aircraft and space, biomedical, composits etc are applications
