Chitosan　films　plasticized　with　the　complex　of　AlCl3·6H2O　and　glycerol　were　prepared　by　using　AlCl3·6H2O　as　the　solvent.　The　effect　of　AlCl3·6H2O　and　glycerol　complex　with　Chitosan　was　studied　by　SEM,　XRD,　TGA,　and　tensile　testing.　The　complex　would　increase　the　water　resistance　and　destroy　the　crystals　of　chitosan　film.　The　TGA　results　proved　that　the　chitosan　film　plasticized　with　the　complex　showed　higher　thermal　stability　at　the　temperature　below　200　°C　than　pure　chitosan　film.　With　the　addition　of　the　complex　of　AlCl3·6H2O　and　glycerol,　the　tensile　strength　of　chitosan　film　decreased　and　the　elongation　at　break　increased.　©　2019,　©　2019　Taylor　&　Francis　Group,　LLC.
