In　this　study,　a　series　of　novel　quaternized　poly(vinyl　alcohol)/chitosan/molybdenum　disulfide　(QPVA/CS/MoS2)　anion　exchange　membranes　(AEMs)　were　prepared　for　direct　methanol　alkaline　fuel　cell　(DMAFC).　The　composite　membrane　was　synthesized　by　adding　different　amounts　of　MoS2　nanosheets　(0,　0.1,　0.2,　0.5　and　1　wt%)　into　QPVA/CS　mixture　solution　and　using　the　solution　casting　method.　The　crystallinity,　thermal　and　mechanical　properties,　ion　conductivity　and　resistance　to　methanol　of　the　QPVA/CS/MoS2　membranes　were　characterized　by　X-ray　diffraction,　thermogravimetric　analysis,　tensile　testing,　ion　exchange　capacity,　and　methanol　permeability　measurements,　respectively.　The　MoS2　was　homogeneously　dispersed　in　the　membranes.　The　mechanical　strength　of　the　composite　membranes　was　enhanced　with　the　addition　of　MoS2.　With　the　addition　of　1.0　wt%　MoS2,　the　QPVA/CS/MoS2　composite　membrane　has　the　lowest　methanol　permeability　of　0.210　×　10−7　cm2·s−1.　This　study　confirmed　that　the　novel　QPVA/CS/MoS2　membrane　would　be　a　potential　candidate　for　the　application　in　DMAFCs.　©　2017
