摘要:
The present disclosure describes a method for forming microporous and antimicrobial articles. The method comprises preparing an initial composition containing a semicrystalline polylactic acid material, a nonpolymeric aliphatic ester diluent, and a nucleating agent. The initial composition is heated to form a melt blended composition. Upon cooling, the melt blended composition phase separates into a composition having two continuous phases. A network of interconnected micropores may be formed by stretching the composition, by removing at least a portion of the nonpolymeric aliphatic ester diluent from the composition, or a combination thereof.
