Abstract:
Disclosed is a process for fabricating microporous, open-cell foam of a hierarchical structure from a composition comprising a foamable liquid polymer, a curing agent for the polymer, a blowing agent and a filler that functions as a viscosity modifier for the foam-forming composition. By appropriate selection of materials, microporous, open-cell polymer foam is producible which, due to its hydrophobic character, is capable of absorbing relatively low surface tension liquids, e.g., hydrocarbon oils, and reject high surface tension liquids, e.g., water. These foams may be applied in maritime oil spill clean-up operations.
