基于几丁质修饰的蒙脱石得到 chitosan/montmorillonitebionanocomposites (CSMMT).  通过分析原料和生物合成材料的结构和表面特征来分析新合成物。

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