웨어러블 디바이스용 유연 전극 소재 개발을 위해 탄소섬유 토우(carbon fibers tow)의 전처리에 따른 전기화학적 특성을 조사하고, 이를 활용하여 포도당을 타겟으로 전기화학적 비효소 센서를 제작하였다. 탄소섬유 토우는 탈사이징(desizing)과 활성화(activation) 공정을 통해 전처리 되었으며, 활성화는 화학적 산화와 전기화학적 산화의 두 가지 방법으로 이루어졌다. 전처리된 샘플은 주사전자 현미경(SEM)을 이용하여 표면 분석되었으며, 전기화학적 특성 및 센싱성능 분석은 시간대전류법와 순환전압 전류법, 전기화학 임피던스 분석법을 이용하여 수행되었다. 탄소섬유 토우는 전처리를 통해 감소된 R_et와 ΔE_p, 증가된 I_p 등 향상된 전기화학적 특성을 보였으며, 두 활성화 방법에서는 유사한 전기화학적 특성이 얻어졌다. 본 연구에서는 전기화학센서 적용을 위해 전기화학적으로 활성화된 탄소섬유 토우를 최종 전극 물질로 선정하였다. 이 전극을 기반으로 제작된 비효소적 포도당 검출 센서는 0.09899~3.754 mM과 3.754~50 mM의 선형 구간에서 각각 0.744 mA/mM과 0.330 mA/mM 정도의 향상된 감도를 보였다. 본 연구를 통해 탄소섬유 토우의 전극 소재로서 사용 가능성을 확인했으며, 고성능 유연 전극 소재 개발에 기초 연구로 활용 가능할 것으로 기대된다.

Abstract ▼ AI-Helper

To develop flexible electrode materials for wearable devices, we investigated the electrochemical characteristics of carbon fibers tow according to pretreatment. And an electrochemical non-enzymatic sensor was fabricated using glucose as a target. The carbon fibers tow was pretreated through desizing and activation processes, and activation was performed in two ways: chemical oxidation and electrochemical oxidation. Surface morphology of carbon fibers tow samples was observed by SEM and their electrochemical characteristics and sensing performance were investigated by cyclic voltammetry, electrochemical impedance spectroscopy and chronoamperometry. Carbon fibers tow samples showed improved electrochemical properties such as reduced Ret, ΔEp, and increased Ip through pretreatment. And similar electrochemical properties were obtained with both activation methods. We selected electrochemically activated carbon fibers tow as the final electrode material for application of electrochemical sensor. The non-enzymatic glucose sensor based on this electrode has an enhanced sensitivity of 0.744 A/mM (in a linear range of 0.09899~3.75423 mM) and 0.330 mA/mM (3.75423~50 mM), respectively. Through this study, the possibility of using carbon fibers tow was confirmed as an electrode material. It is expected to be used as basic research for development of high-performance flexible electrode materials.
