Characterization of chitosan/montmorillonite bionanocomposites by inverse gas chromatography

Résumé

Montmorillonite was modified with different amounts of chitosan to obtain chitosan/montmorillonite bionanocomposites (CSMMT). The structural and surface characteristics of the raw materials and bionanocomposites were analyzed. XPS results showed that the obtained bionanocomposites had MMT-rich surfaces with chitosan essentially intercalated in the host clay galleries. IGC at infinite dilution confirmed that the increase of CS mass ratio in the bionanocomposites significantly affected the surface properties. IGC at finite concentration revealed a clear evolution in the surface heterogeneity in chitosan/montmorillonite bionanocomposites by the progressive disappearance of shoulders of high energy with the increase of CS mass ratio in MMT
