Abstract
A method of forming foam includes providing a foam with at least one of chitosan, chitin, or chitosan oligosaccharide, where the foam has a density of 1 g/cm3 or less. The method further includes placing the foam between tooling, applying heat to the foam, and pressing the foam into a shape using the tooling.
