The　simple　LBL　technique　was　introduced　to　fabricate　green　nacre-like　chatosan/montmorillonite　(CHI/MMT)　films.　The　results　of　SEM　and　XRD　analysis　demonstrate　that　the　produced　CHI/MMT　composites　films　stacked　densely　together　to　bring　out　well-defined　nacre-like　brick-mortar　structure.　The　nanoindentation　technique　is　used　to　characterize　the　mechanical　properties　of　the　layered　nanocomposite　films,　which　show　enhanced　mechanical　modulus　(up　to　similar　to　6.64　GPa)　compared　with　the　pure　chitosan.
