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.
Claims10
An organic solid three-dimensional polymeric foam consisting of, or comprising, a solid continuous phase and pores,
- wherein said solid continues phase is a cross-linked organic polymer,
- wherein said pores are separated by plateau borders, the meeting points of said plateau borders forming nodes,
- wherein said foam has:
- a pore size comprised from 50 nm to 100 μm,
- a volumetric fraction of the solid continuous phase comprised from 0.1 to 60%, with respect to the total volume of the foam,
- a flexibility/elasticity comprised from 10 to 107 Pa,
- a polydispersity index comprised from 1 to 30%,
- wherein said solid three-dimensional polymeric foam is ordered over a volume of at least 100 pores, or over a volume of 100 to 1000 pores, or 1000 pores.
