DEVELOPING HIGH-PERFORMANCE GAS SENSORS BY FUNCTIONAL COVALENT ORGANIC FRAMEWORKS
Abstract
The development of advanced gas sensing technology is highly relevant to smart life and industry. However, conventional gas sensing materials demonstrate limited performance and stability in practical applications. In this project, we aim to develop advanced covalent organic framework (COF)-based gas sensors with high selectivity, short response time, high stability (minimized performance drift), and improved tolerance to harsh environments through rational COF design and advanced COF film fabrication technology. The project consists of three main stages. The first stage involves the design of application-oriented functional COFs for gas sensing. we will manipulate COF pore sizes and regulate COF functionalities. The second stage involves the integration of COFs into a final sensor device. we will employ coating and in situ growth methods to fabricate COF-based gas sensor devices. The last stage of the project involves the evaluation of the sensing performance of the resultant COF-based gas sensors. Through this project, we aim to develop high performance gas sensors by functional COFs and initiate a sustainable and high value added gas sensing technology for future U.S. Air Force (USAF) and U.S. Space Force (USSF) systems.
