Abstract

Nanohybrids were fabricated from a poly(l-lactic acid) solution loaded with various concentrations of organically modified montmorillonite. Investigation of the produced composites' morphology by X-ray diffraction analysis, transmission electron microscopy and atomic force microscopy revealed a coexistence of intercalated and exfoliated clay particles, with the latter ones being predominant for low filler loadings. Porous scaffolds of pure and nanocomposite poly(l-lactic acid) were prepared using supercritical CO₂ as antisolvent and the influence of montmorillonite content was examined. It was observed that the final cellular structure was strongly related to the filler content.
