For　device　printing,　it　is　important　for　uniform　films　to　be　printed　because　the　morphology　of　the　film　affects　the　performance　of　the　device　in　inkjet　printing.　In　this　study,　to　prepare　stable　and　well-dispersed　ink,　polyacrylate　and　silicone　surfactant　BD-3033H　were　added　to　ink.　Then　a　uniform　quantum　dot　(QD)　film　was　obtained　by　optimizing　the　polyacrylate　and　silicone　surfactant　contents　of　the　ink　as　well　as　the　substrate　temperature.　The　change　of　the　polyacrylate　structure　from　a　curly　chain　structure　to　a　three-dimensional　network　structure　blocked　the　outward　flow　of　QDs.　Silicone　surfactant　BD-3033H　caused　Marangoni　flow　and　made　the　QDs　flow　inward.　When　the　substrate　temperature　was　increased,　the　solvent　evaporation　rate　was　accelerated,　the　contact　line　was　pinned,　and　the　outward　flow　was　enhanced,　which　changed　the　film　structure　from　convex　to　flat.　Finally,　when　the　polyacrylate　content　was　12　wt%,　the　silicone　surfactant　BD-3033H　content　was　0.10　wt%,　the　substrate　temperature　was　40　degrees　C,　and　the　coffee　ring　effect　was　eliminated.　A　uniform　QD　film　was　printed,　providing　a　technical　guarantee　for　the　fabrication　of　QD　devices　in　the　future.
