Abstract

The hydrolytic degradation of polylactic acid - layered silicate composites was investigated in an aqueous solution with pH 10.5 at 50°C for 28 days. Semicrystalline and amorphous resins were melt mixed with unmodified and organo-modified montmorillonite clays at different loadings to produce micro- and nanocomposites, respectively. Hydrolytic degradation rates were found to be dependent on type of polymer and filler surface treatment. The effects of degradation on morphology and thermal properties as a function of time were investigated by scanning electronic microscopy and differential scanning calorimetry, respectively.
