Process for obtaining composite materials based on crosslinked polymers and fluid molecules including a drying step in supercritical phase

摘要

Obtaining a composite material consisting of a crosslinked polymer (P) and fluid molecules (M) comprises: making a porous film (F) of crosslinked polymer having liquid crystal (xL)o in the body of the pores; immersing the film in a solvent (S) of the liquid crystal to dissolve it, drying the film in conditions of pressure (PE) and temp. (TE) approaching or in the supercritical phase. Filling the dried film with the molecules (M).
