摘要

本實驗室致力於軟性電子製程開發，其重點在於有機薄膜的圖案化技術，而本技術的關鍵點在於如何在低溫時隨意控制薄膜均勻性之下製作出的有機薄膜圖案，而本實驗室開發之創新物理吸附式微接觸印刷之轉移上墨技術並且發明了「使用溶劑預潤濕之微接觸印刷技術」，溶劑潤濕的優點在於可以增加高分子薄膜表面的平整性以及可以在室溫下轉印高分子薄膜，本實驗室使用的印模為具二甲基矽氧烷(poly(dimethyl siloxane)，PDMS)是一種多孔性材料能夠吸收有機溶劑，造成PDMS矽膠表面形變，我們使用高分子溶液的溶劑大多會被PDMS矽膠吸收，如甲苯(Toluene)，而我們將採用不易被PDMS矽膠吸收之溶劑作為預潤濕做為之後的討論。
在本論文中，將繼續探討關於溶劑潤濕對於高分子薄膜的影響以及當使用用溶劑潤濕時對PDMS矽膠的表面自由能以及吸附功之影響，且溶劑潤濕使用在微接觸印刷的上墨與轉印之影響探討一併討論後，將此技術的理論完整建立並與實驗整合

Our group have devoted to flexible electronics fabrication for a long time.There are three key issues for flexible electronics fabrication: patterning thin film on substrate without heating, the uniformity and thickness controllability of the thin film. and using Innovative μCP process” (Innovative Micro-Contact Printing process) , the stamp used in our group as a (poly(dimethyl siloxane)，PDMS), it is a porous material capable of absorbing an organic solvent, resulting in deformation of PDMS silicon surface, we used most of the polymer solvent solution may be PDMS silicone absorption, such as toluene (Toluene), and we will use PDMS silicone can not easily be absorbed by the solvent as a pre-wetting as discussed later.
In this thesis, we will continue to explore the wetting solvent for the polymer thin film on the effect and when solvent wetting when using PDMS silicone surface free energy and the effect of adsorption reactive, and the solvent wetting of the micro-contact inking&printing explore the effect of the transfer be discussed, the theory of this technology to create and complete integration with the experimental.
