BIODEGRADABLE POLYMER PARTICULATES AND METHODS FOR PRODUCTION AND USE THEREOF

Compositions include a plurality of polymer particulates comprising a matrix polymer and one or more types of nanoparticles selected from the group consisting of biopolymer nanoparticles, biomineral nanoparticles excluding biomineralized silica alone, and any combination thereof. Illustrative examples of such nanoparticles may include cellulose nanoparticles, hydroxyapatite nanoparticles, or any combination thereof associated with the matrix polymer. The polymer particulates may be prepared by melt emulsification. Methods include depositing such polymer particulates in a powder bed; and heating a portion of the powder bed to consolidate a portion of the polymer particulates into a consolidated part having a specified shape. The matrix polymer may be biodegradable and lose at least about 40% mass in six days in a phosphate buffer solution (0.2 M, pH 7.0) containing 0.2 mg/mL of lipase obtained from Pseudomonas cepacia (≥30 U/mg) and incubated at 37° C.
