Abstract

Fibers and an anionic polymer can be combined together in solution to form a slurry. Each fiber can comprise cellulose, and the anionic polymer can have one or more free anion groups. Metal ions and a foaming agent can be added to the slurry. The slurry can then be dried to form a foam, in which the metal ions are bonded between the anion groups of the anionic polymer. In some examples, the foam can be used as a thermally-insulating structure, for example, having a thermal conductivity less than or equal to 0.04 W/(m∙K). Alternatively, the foam can be used as a substrate for plant growth.
