建立了一个描述溶剂蒸发动力学的模型。结合一个单一的拟合参数，它表明，该公式可以准确地预测各种涂层条件下的加工窗口。通过区域浇铸装置制造的有机薄膜晶体管（OTFT）在预测的涂覆速度下确实显示出最佳性能，迁移率达到7 cm（2）V-1 s（-1）。
A model that describes solvent evaporation dynamics in meniscus-guided coating techniques is developed. In combination with a single fitting parameter, it is shown that this formula can accurately predict a processing window for various coating conditions. Organic thin-film transistors (OTFTs), fabricated by a zone-casting setup, indeed show the best performance at the predicted coating speeds with mobilities reaching 7 cm(2) V-1 s(-1).
