The invention provides new high-use temperature lightweight polymer/inorganic , nanocomposite materials (37 39) with enhanced thermal stability and performance characteristics. The invention provides two techniques that enhance the thermal stability of the nanocomposite systems (37 39) from their , current limits of 100-150 ~C to over 250 ~C. The two unique approaches are based on innovative chemical design of the organic-inorganic interface using (i) more thermally stable surfactants/compatibility agents and (ii) more , thermally stable synthetic organically-modified layered-silicate reinforcements (23) to create unique nanocomposites (37 39). The new , technonogy provides hitherto …

Why it's free to use
- Filed March 23, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 23, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 23, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
