2. INTRODUCTION
“A composite is a combination of two or more different materials that are mixed
in an effort to blend the best properties of both.”

3. What are Nanocomposites?
“ A Nanocomposite is a composite material, in which one of the components
has at least one dimension that is around 10-9 m.

5. PREPARATION METHODS
 In situ polymerisation
 Melt mixing
 Solution mixing
 Precipitation
 Sol-gel process
 Electro spinning

8. Electrospraying
 It is a process similar to electrospinning but is used when
the viscosity of the liquid is sufficiently low.
 In electrospraying the size of the droplets can be controlled
mainly by the liquid flow rate, and the droplet charge by
adjusting the voltage applied to the nozzle.
