本研究將分為兩個部份探討，並且皆以金屬有機框架（Metal-organic framework, MOF）為核心，根據其特定的特性去開發相關應用。第一部分中，我們將金屬有機框架引入基於深共熔溶劑（Deep eutectic solvents, DES）的離子凝膠系統，並結合3D列印技術，開發出具有優異機械性能的可穿戴感測設備。當暴露於酸性環境時，凝膠中以鋯為基底的金屬有機框架會呈現顏色變化，使這些可穿戴傳感器不僅能夠記錄人體活動產生的信號，還能作為環境檢測的指示器。
第二部分中，我們探索了定向冷凍所製備之金屬有機框架複合材料在電化學應用中的潛力。將導電高分子Poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS)之水溶液定向冷凍後，可製備出利於UiO-66成長的巨孔氣凝膠結構。儘管金屬有機框架本身導電性較差，但我們可以通過後修飾的方式來增強其電荷傳輸的性能。結合金屬有機框架與導電聚合物PEDOT:PSS形成導電複合材料，我們成功開發出具有高功率密度和快速充放電能力的超級電容器。此外，我們發現PEDOT：PSS能夠用於3D列印技術，提供更多電化學相關應用的機會。

This study is divided into two parts, both centered around metal-organic framework (MOF), with each part focusing on developing related applications based on their specific characteristics. In the first part, we incorporate MOF into an ionogels system based on deep eutectic solvents (DES), and combine this with three-dimensional printing technology to develop wearable sensing devices with excellent mechanical properties. Additionally, zirconium-based MOF exhibits a colorimetric change when exposed to acidic environments, making these wearable sensors capable of recording signals generated by human activities and serving as indicators for environmental detection.
The second part explores the potential of MOFs-based composites prepared by directional freezing in electrochemical applications. Directional freezing of poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT:PSS) aqueous ink leads to PEDOT:PSS aerogels with macropores for efficient growth of UiO-66. Post-synthetic modifications further overcome the inherently poor conductivity of MOF. The resulting Mn-UiO-66/PEDOT:PSS composite can be used as supercapacitors with high power density and rapid charge-discharge capabilities. Furthermore, the PEDOT:PSS aqueous ink can also be utilized in 3D printing to facilitate additional electrochemical applications.
