本研究製備了聚乙烯亞胺-沸石咪唑骨架/多壁奈米碳管(Polyethylenimine-
Zeolitic imidazolate framework-8/Multi-walled carbon nanotubes, PEI-ZIF-8 /MWCNTs)之雙層材料，將其運用於人體呼氣之二氧化碳濃度監測，以應用於慢性肺阻塞病患者之病情監控及相關數據之收集。
實驗上首先將MWCNT以噴塗法塗佈於網版印刷碳電極上，作為電子訊號傳輸層，接著合成PEI-ZIF-8複合材料，並再將其噴塗於電極上，運用PEI內富含胺基及ZIF-8的多孔特性，使其對於二氧化碳產生高量吸附之能力，當通入二氧化碳後電極之電阻會產生變化，以此做為判斷二氧化碳濃度之依據。本研究所製備之電極，在室溫環境、相對溼度10%的情況下，對於5 %濃度之二氧化碳(正常人呼氣之二氧化碳濃度)，可達5.29%之響應值(Response)，且在2.5%~12.5%之二氧化碳濃度區間內，訊號隨二氧化碳濃度增加呈現線性正相關之關係，顯示其對於二氧化碳濃度具有良好之判斷能力，在多次測試下也呈現穩定之響應訊號，在人體實際呼氣的狀況下也呈現良好的感測表現。
本研究之電極及材料製備方法簡單、成本低廉，可直接於室溫環境下使用，且具有非侵入性、能簡易使用之特性，對於臨床醫學監測人體呼氣二氧化碳濃度之應用具極大的潛力。

In this study, a polyethyleneimine-zeolitic imidazolate framework/multi-walled carbon nanotubes (PEI-ZIF-8/MWCNTs) double-layer electrode is prepared and applied to monitor the concentration of carbon dioxide (CO2) in human breath, aiming to monitor the physical health of patients with chronic obstructive pulmonary disease. In experiment, MWCNTs, used as the electron transport layer, are first coated on the screen-printed electrode by spray coating, and then the PEI-ZIF-8 solution is synthesized and sprayed on the electrode as the CO2 adsorption layer. The electrode with rich amine groups in PEI and the porous characteristics of ZIF-8 results in good ability to absorb CO2. The resistance varied in the presence of CO2 is used to determine the CO2 concentration. The sensor prepared in this work can reach an average response of 5.29% under 5% CO2 and 10% relative humidity at room temperature (RT). In addition, the response shows good linear relationship versus CO2 concentration in the range from 2.5% to 12.5%. In human breath test, the sensors also show good sensing behavior. The preparation of sensors and materials in this study are simple, low-cost, and the sensor possesses the characteristics of operation at RT, non-invasive and easy to use. The uniqueness of the electrode shows great potential for the application of clinical research to monitor the CO2 concentration of human breath.
