Abstract

A material having the characteristics of very low density and high mechanical stability has been developed. This material is prepared by crosslinking the biopolymer alginic acid. Bulk densities as low as 0.15 g/cc have been obtained, while still possessing useful strength, 10% deformation at 347 psi. The physical properties can be varied by controlling the processing conditions, which affect pore volume, pore diameter, bulk density and surface area. Preparation of this material involves solvent exchange and subsequent crosslinking. The resin's minimum compressibility and physical strength allow this material to be considered for a number of applications including adsorbents, insulation and as a polymeric carrier for time release.
