Abrégé
(EN)
Improved mechanical properties of either clay or carbon nanotube (CNT)-reinforced polymer matrix nanocomposites are obtained by pre-treating nanoparticles and polymer pellets prior to a melt compounding process. The clay or CNTs are coated onto the surfaces of the polymer pellets by a milling process. The introduction of moisture into the mixture of the nanoparticles and the polymer pellets results in the nanoparticles more easily, firmly, and thoroughly coating onto the surfaces of the polymer pellets.
(FR)
Selon la présente invention, des propriétés mécaniques améliorées de nanocomposites de matrice de polymère renforcés de nanotubes d'argile ou de carbone (CNT) sont obtenues par prétraitement de nanoparticules et de granules de polymère avant un processus de formulation à chaud. L'argile ou les CNT sont appliqués sur les surfaces des granules de polymère par un procédé de broyage. L'introduction d'humidité dans le mélange des nanoparticules et des granules de polymère conduit à une application plus aisée, plus résistante et plus uniforme sur les surfaces des granules de polymère.
