中文摘要: 聚合物半导体纳米结构能够有效地消除晶界,减少电荷陷阱密度,极大地提高器件性能。同时将纳米结构与器件制备相结合,还可以满足对器件小型化和集成化的要求。本项目在纳米压印技术基础上提出了一种制备大面积分离的有机聚合物半导体纳米结构的新方法-纳米切割。从有机聚合物半导体材料种类和薄膜厚度、刚性模板的形状和尺寸、切割过程压力、温度和速度,以及聚合物基底流动性作用四个方面入手,研究有机聚合物半导体层的在刚性模板切割过程中的断裂力学过程,建立纳米切割理论模型。此方法还可以用于构筑了由多种材料组成的异质纳米结构,如聚合物/金属,聚合物/聚合物等多层纳米结构。同时本研究将利用有限元方法对纳米切割过程进行仿真模拟,找出影响纳米切割效果的主要因素,为实验过程优化提供理论指导。最后将发展的纳米切割方法应用于高性能有机光电器件的制备,为发展适宜于未来塑性器件卷帘式加工提供新思路。

英文摘要: Polymeric semiconductor nanostructures can effectively eliminate the grain boundary, reduce the charge trap density, and greatly improve the device performance. A combination of nano structure and device fabrication can meet requirements of the miniaturization and integration of the device. Based on nanoimprint lithography, a new method for preparation large area separated polymeric semiconductor nanostructure was proposed in our project. From four aspects of polymeric semiconductor and thickness of film, shape and pattern size of rigid master, pressure\temperature and velocity in nanoscale cutting, viscous of polymer substrate, we analyses fracture mechanics of polymeric semiconductor film when comprises master into a polymer multilayer structure and established the nanoscale cutting model. The hybrid nanostructure, such as polymer/metal and polymer/polymer, also can be prepared by nanoscale cutting. This research will also analyze and discuss nanoscale cutting with the finite element methods for the preparation of highly oriented and stable polmer nanostructure. And the development of nanoscale cutting method is applied to preparation of high-performance organic electronic devices, suitable for the development of plastic devices in the future roll-curtain processing providing new ideas.
