Abstract
L'invention concerne un procédé de fabrication d'un matériau composite comprenant des dispersions solides d' une substance active dans une matrice polymère, le procédé étant caractérisé en ce qu' il comprend les étapes suivantes : - l'étape d'introduire la matrice polymère dans une extrudeuse (1) , - l'étape d'actionner l' extrudeuse (1) de manière à modifier des propriétés rhéologiques de la matrice polymère, - l'étape de placer un fluide dans des conditions supercritiques et de l'injecter, pur ou mélangé avec un autre constituant dans l' extrudeuse (1), notamment via une buse d'injection (11), l'étape d'introduire une substance active dans l ' extrudeuse ( 1 ) , - l'étape de mélanger le fluide supercritique, la substance active et la matrice polymère, - l'étape de détendre le mélange ainsi obtenu afin de lui conférer une structure microporeuse.
