    Abstract: Biofoam is a rigid, microcellular organic foam made from organic materials derived from natural products and biological organisms. Starting materials include agar, agarose, gelatin, algin, alginates, gellan gum, and microcrystalline cellulose. The organic material is dissolved in a polar solvent, typically water, and the mixture is gelled. The water in the gel pores is replaced at least once with another solvent to reduce the pore size of the final biofoam. The solvent in the gel pores may be replaced several times. After the final replacement of solvent, the gel is frozen and freeze-dried to form a biofoam. Translucent biofoams are formed by selecting a final solvent that forms very small crystals. A variety of crystalline, fibrous, amorphous, or metallic additives may be incorporated into the foam structure to produce lightweight composite materials with enhanced strength and insulating properties.

    Abstract: A method for preparing a highly porous, high surface area non-degradable material, comprises the steps of mixing a non-degradable polymer with a solvent or mixture of solvents; gelling the mixture; and treating the gel under conditions whereby a substantially solvent free porous structure is created having a porosity greater than about 80%. The resultant material is mechanically strong and has an architecture comprising at least one of nano fibrous, micro fibrous, non fibrous, complex porous structure with nano fibrous architecture, and mixtures thereof.
