5. Nanocomposite applications
Polymer matrix processing is currently well mastered and inexpensive, and clays are easy to extract. These two factors make them ideal candidates for new materials with specific properties (see Table A at
5.1 Barrier properties
The aim is to be able to substitute these new materials for glass or technical polymers. This mainly concerns food packaging and, in particular, containers for liquids. These bottles are transparent, impermeable to gas and better able to retain aromas.
This has led to the development of polyamide matrix nanocomposites with both active and passive oxygen barrier properties (Honeywell). The presence of clay...

Expenses
Nanotechnologies, in the broadest sense of the term, now represent a real economic challenge. The financial efforts of countries such as the United States, Japan and the European Union in this field have been growing rapidly since the late 1990s. Public support for nanotechnologies in all countries combined totaled 3.5 billion euros in 2003. It is growing at a rate...
