On-Demand Microwave-Assisted Fabrication of Gelatin Foams
Ultraporous gelatin foams (porosity >94%, ρ ≈ 0.039–0.056 g/cm3) have been fabricated via microwave radiation. The resulting foam structures are unique with regard to pore morphology (i.e., closed-cell) and exhibit 100% macroporosity (pore size 332 to 1700 μ...
