Abstract

Organic solid three-dimensional polymeric foams, a process for preparing the same, and use thereof, the foams includes a solid continuous phase and pores, wherein the foams have a pore size ranging from 50 nm to 200 μm and a volumetric fraction of the solid continuous phase is from 0.1 to 60%, with respect to the total volume of the foams, and a polydispersity index from 1 to 30%, the foams being ordered over a volume of at least 100 pores.
