Abstract

Controlled morphology of nanoclay layers within nanopolymer particles is a very
important topic for most industries, especially in food and medical packaging. Films
prepared from these nanocomposites showed improved physical and mechanical properties
and high impermeability towards gases, vapors, water and even oils and hydrocarbons.
One successful method to design these systems is by miniemulsion polymerization which
is useful for encapsulation of all materials (solids, liquids and gases) within polymer
particles, provided a suitable choice of surfactant is made with optimum HLB. Another
method is "pickering" or soap free polymerization, which can also be performed in the form
of miniemulsion. In this new method nanoclay is used instead of a surfactant, and therefore,
final films will show honeycomb structures applicable in impermeable packaging purposes.
