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 unobtainable thermal stability and performance characteristics, and has numerous applications in automotive, aerospace, electronic and food and beverage industries.

La présente invention concerne de nouveaux matériaux nanocomposites polymères/inorganiques (37, 39) légers utilisés à haute température, présentant des caractéristiques améliorées en terme de rendement et de stabilité thermique. Cette invention concerne deux techniques qui améliorent la stabilité thermique de ces systèmes nanocomposites (37, 39) par rapport à leurs limites actuelles comprises entre 100-50 C et plus 250C. Ces deux techniques uniques reposent sur la nouvelle conception chimique de l'interface organique-inorganique utilisant: (I) des agents de compatibilité/tensioactifs thermiquement plus stables, et (II) des renforts (23) de silicate en couches synthétiques organiquement modifiés et thermiquement stables, pour obtenir des nanocomposites (37, 39) uniques. Cette nouvelle technologie fournit des caractéristiques de stabilité thermique et de rentabilité jamais obtenues jusqu'ici, et présente de nombreuses applications dans les industries de l'automobile, de l'aéronautique, de l'électronique et dans l'industrie des aliments et des boissons.
