摘　　要：采用物理共混的简易方法制备了壳聚糖/绢云母复合薄膜。场发射扫描电镜观测的结果表明,这种薄膜具有明显的取向"砖-泥"仿贝壳结构。这种独特仿生结构的形成显著地提高了壳聚糖复合薄膜的力学性能(拉伸强度和断裂伸长率),并且保持了优异的柔软弯曲性能。同时,这种复合薄膜具有良好的透明性和电绝缘性能。The chitosan/sericite composite film was prepared by blending plate-like sericite and chitosan. The Scanning electron microscope result indicated that the composite film has typical＂brick-mortar＂orientation microstructure. The mechanical properties（tensile strength and elongation at break） of the film were enhanced apparently with the incorporation of sericite, whilstthe films preserved good flexibility on account of the unique structure. Furthermore, the composite film exhibited excellent properties in transparency and insulation.
