摘要： The present disclosure relates to a process of manufacturing a multicellular structure comprising interconnected cells, wherein the process comprises:
a) providing a polymerizable precursor of a polymeric material, wherein the polymerizable precursor comprises a reactive monomer mixture;
b) providing a mold comprising precursor structures of the multicellular structure;
c) optionally, heating at least one the reactive monomer mixture or the mold;
d) incorporating the reactive monomer mixture into the precursor structures of the multicellular structure thereby substantially filling up the precursor structures of the mold, wherein the reactive monomer mixture has a viscosity of no greater than 10,000 mPa-s when incorporated into the precursor structures of the multicellular structure and when measured according to the viscosity test method defined in the experimental section;
e) polymerizing the polymerizable precursor of the polymeric material into the precursor structures of the mold; and
f) demolding the multicellular structure formed by polymerizing the polymerizable precursor of the polymeric material.
According to another aspect, the present disclosure relates to a multicellular structure obtainable by the process as described above. In another aspect, the present disclosure relates to the use of a multicellular structure as described above for industrial applications.
