Membrane gas sensors with rapid detection of CO2 concentration have applications ranging from oceanic measurements to the oil and gas industry. The response time of the gas sensors, which inc_orporates a gas permeable membrane, is inherently limited by the permeance of the targeted analyte through the membrane. Commercial CO2- permeable membranes, such as PDMS, have low gas permeability and permeance and poor selectivity.This proposal aims to design and fabricate new gas permeable membranes using high CO2 permeability membrane materials known as polymers of intrinsic microporosity (PIMs). We aim to achieve high CO2 gas permeance (above 2000 GPU) and high selectivity towards water. We will also integrate the membranes in the sensor device and evaluate the performance in the device which will provide feedback for improvement of the membrane design and surface modification for improvement of resistance towards biofouling and ageing.

可快速检测二氧化碳浓度的膜气体传感器的应用范围从海洋测量到石油和天然气行业。包含气体渗透膜的气体传感器的响应时间本质上受到目标分析物通过膜的渗透性的限制。商业CO2渗透膜，如PDMS，气体渗透率和渗透性较低，选择性较差。该提案旨在使用被称为固有微孔聚合物（PIM）的高CO2渗透性膜材料来设计和制造新型气体渗透膜。我们的目标是实现高 CO2 气体渗透性（2000 GPU 以上）和对水的高选择性。我们还将把膜集成到传感器设备中，并评估设备的性能，这将为改进膜设计和表面改性提供反馈，以提高对生物污垢和老化的抵抗力。
