本題目主要是針對噴墨印刷技術應用的開發，主要是利用現今熱門的二維材料去加以應用，其中石墨稀和二硫化鉬現在是備受矚目的二維材料，由於其特別的結構及在薄膜電晶體和電化學儲能方面有許多團隊有深入的研究
二硫化鉬在鋰電池的陽極應用中，在充放電的過程中使得二硫化鉬的結構瓦解，使得循環壽命不佳，因此在許多文獻將碳或是石墨烯透或化學合成方法加入二硫化鉬形成異質結構，但也因此需要花費較長的合成時間。在本題目將二硫化鉬和石墨稀分別製造成可噴塗的墨水，透過噴墨印刷技術將二硫化鉬和石墨稀印刷成型，形成層層交錯堆疊的二硫化鉬/石墨稀異質結構，在此研究中鋰離子電池經過460次的循環後還保持806 mAh/g 的電容量在0.6 A/g的電流下，相較於一般塗佈的方法下有較優異的電容量和壽命；另外在鈉離子電池的陽極應用中經過668次的循環後還保持510 mAh/g 的電容量在0.6 A/g的電流下，相較於一般塗佈的方法下有較優異的壽命。
本題目不僅將噴墨印刷應用在儲能方面，也製作出全噴墨印刷的光電感測器，由於以往感測器都需要多道製程需要較多的時間和較高的成本，但是利用噴墨印刷技術能夠快速製作出感測器，同時也能降低成本，用來驗證科學實驗的可行性。在全噴墨印刷的光電感測器中展現出4、3 和2nA 的光電在632、515和404 nm波長的雷射中 (雷射功率= 10mW,Vds= 3V) 在玻璃基板上，另外還製作了可彎曲的光電感測器在聚醯亞胺(PI)基板上，經過了500次的彎折後，光電流還保持2nA在404 nm波長的雷射中 (雷射功率= 10mW,Vds= 3V)。

This thesis is mainly for the development of inkjet printing technology applications, mainly using two-dimensional materials to apply, among which Graphene and Molybdenum disulfide is now a high-profile two-dimensional material, due to its special structure and There are many teams with in-depth research on thin film transistors and electrochemical energy storage.
In the Li-ion battery anode’s application, the MoS2 structure is collapsed during the charging and discharging process, resulting in poor cycle life. Therefore, in many literatures, carbon or graphene is added to the MoS2 by chemical synthesis to form a heterostructure, but it also takes a long time to syn-thesize. In this thesis, MoS2 and Graphene are separately made into printable ink, and MoS2 and Gra-phene ink are printed by inkjet printing technology to form a heterostructure of MoS2 /Graphene which is stacked in layers. In this study, the Li-ion battery maintained a capacitance of 806 mAh/g at a current of 0.6 A/g after 460 cycles, which has batter capacitance and lifetime compared to the general coating method; In the Na-ion battery anode application, after 668 cycles, the capacity of 510 mAh/g was maintained at a current of 0.6 A/g, which was superior to the general coating method.
Not only applies inkjet printing to energy storage, but also produces a full-inkjet print photodetec-tor. Since the previous sensors require multiple processes, more time and higher cost are required, but the use of the Ink-jet printing technology can quickly produce sensors, while also reducing costs, to verify the feasibility of scientific experiments. 4, 3, and 2nA of photocurrent in full inkjet printed pho-todetector at 632, 515, and 404 nm wavelengths (laser power = 10 mW, Vds = 3 V) on glass substrates, A flexible photodetector was fabricated on a polyimide substrate. After 500 bends, the photocurrent was maintained at 2 nA in a 404 nm laser (laser power = 10 mW, Vds). = 3V).
