Solid composite

Abstract

The present invention relates to a solid composite, comprising: a first polymer, preferably solid having a porous structure; a second polymer, preferably different from said first polymer; a first additive, preferably selected from perovskite; and optionally a second additive; wherein said solid composite is prepared by first mixing the monomers for said first polymer with said second polymer, said first additive, and optionally said second additive, then solidifying said monomers to form said first polymer by means of polymerization, whereby said second polymer, said first additive, and optionally said second additive are dispersed in the porous structure of said first polymer.
