Abstract:
1. A biodegradable nanocomposite comprising: a biodegradable polymer; a reinforcing agent comprising a clay substantially dispersed throughout the biodegradable polymer by rapid depressurization of a supercritical fluid, the clay having an increased platelet spacing after dispersion throughout the biodegradable polymer by rapid depressurization of the supercritical fluid relative to the clay prior to the supercritical fluid treatment; and a plurality of pores formed in the nanocomposite, the plurality of pores having an average pore size greater than about 100 μm; wherein the nanocomposite comprises a compressive strength of about 6.10 MPa or greater.
