摘要：

Polymethyl　methacrylate　(PMMA)　is　an　indispensable　important　protective　material　in　thetransfer　process　of　graphene　by　PMMA　assisted　method.　In　order　to　analyze　the　effect　of　PMMA　on　the　transfer　quality　of　graphene,the　surface　morphology　and　photoelectric　properties　of　graphene　were　systematically　analyzed　by　Raman　spectrometer,　atomic　force　microscope　(AFM),　UV-Vis　spectrophotometer,　and　Hall　effect　measurement　system.　Results　show　that　the　curing　of　PMMA　plays　an　important　role　in　the　transfer　quality　of　graphene,since　fully　cured　PMMA　can　effectively　support　and　protect　graphene　in　order　to　reduce　gravel　damage,　impurity　adsorption　and　structural　defects　during　the　transfer　process.　In　addition,　the　optimum　curing　temperature　and　time　of　PMMA　solution　were　180　℃　and　120　s,　respectively.　The　corresponding　optical　transmittance,　carrier　concentration　and　mobility　of　graphene　achieved　90%,　6.7×1012　cm-2,　1　500　cm2/(V•s),　respectively.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
