Abstract
An elastomeric material nanocomposite having sufficiently low air permeability to be useful as a tire inner liner among other things, can be prepared by dispersing a layered clay material into the elastomer in the form of packets having an average thickness in the range of about 100 .ANG. to about 1400 .ANG.. Accordingly, the present invention provides in one embodiment, a novel composite composition, and in another embodiment, a novel tire inner liner composition.
Claims10
A composite comprising:
- an elastomer and a layered material dispersed in the elastomer in the form of packets having an average thickness of from about 100 .ANG. to about 1400 .ANG..
A pnuematic tire having a tire inner liner or inner tube comprising an elastomer and a layered material dispersed in the elastomer in the form of packets having an average thickness of from about 100 .ANG. to about 1400.ANG..
A substantially air impermeable elastomer membrane comprising an elastomer matrix having a layered material dispersed therein in the form of packets having an average packet thickness in the range of from about 100 .ANG. to about 1400.ANG..
