Claim 2:
3. The process according to claim 1, comprising:
a step A of microfluidic bubbling of a gas phase through a liquid phase comprising a cross-linkable polymer, a cross-linking agent, a solvent and optionally a stabilizing agent, to obtain an organic liquid polymeric foam comprising a liquid continuous phase and bubbles, and
a step B of cross-linking of said liquid polymeric foam comprising a liquid continuous phase and bubbles, to obtain a first layer of solid polymeric foam comprising a solid continuous phase and pores in reactor B,
and
a sequence of leaving the previously prepared first layer of solid foam in reactor B, and repeating steps A and B to obtain a second layer of solid polymeric foam on top of the first layer of solid polymeric foam, thus increasing the total amount of the solid polymeric foam, to obtain a solid three-dimensional polymeric foam,
said step B of cross-linking being carried out in such a way that cross-linking is only partial, ensuring adhesion between the first and second layers, and
step A of said repeating steps A and B being optionally carried out using different reactors A, or using different microfluidic chips.
