전기 전도성 고분자는 폴리 아세틸렌을 적절한 electron withdrawing group이나 electron donating group을 이용하여 도핑하면 전도도의 증가를 가져온다는 보고 이래로 활발하게 연구되어져 왔다. 그 중에서 폴리피롤은 높은 전도도와 산화안정성, 인체에 무해한 특성 때문에 여러 분야에 응용되고 있으며 분자전자장치나 고체 배터리의 전극, 축전기의 고체 전해질, 전자파 차폐 재료, ion센서, 위장막의 제조 등의 용도전개 잠재력이 무궁하다. (중략)

This study aims to develop electromyography (EMG) textile electrodes and assess their performance and signal stability by examining variations in layer count and fabric types. We fabricated the electrodes through layering and pressing techniques, focusing on configurations with different layer counts (Layer-0, Layer-1, and Layer-2). Our findings indicate that layer presence significantly influences muscle activation measurements, with enhanced performance correlated with increased layer numbers. Subsequently, we created electrodes from five distinct fabrics (neoprene, spandex cushion, 100% polyester, nylon spandex, and cotton canvas), each maintaining a Layer-2 structure. In performance tests, nylon spandex fabric, particularly heavier variants, outperformed others, while the spandex cushion electrodes showed superior stability in muscle activation signal acquisition. This research elucidates the connection between electrode performance and factors like layer number and electrode-skin contact area. It suggests a novel approach to electrode design, focusing on layer properties and targeted pressure application on specific sensor areas, rather than uniformly increasing sleeve pressure.

Spandex is a elastomeric fiber in which the-fiber-forming substance is a long chain polymer consisting of at least 85% segmented polyurethane. In the polyurethanes there are the additional oxygen atoms in the main chains of the molecule. The effect of these oxygen atoms is to make the molecule somewhat more flexible. From a physical point of view, elasicity and recovery from stretch are the most important properties of polyurethane, so its use has now expanded into many kitting industry. In this paper, I wish to Test the effect of dyeing condition on the quality of polyurethane.

Polyurethane(PU)은 내마모성, 내약품성, 내용제성이 좋으며 내노화성과 산소에 대한 안정성이 뛰어난 고분자로서 spandex를 비롯하여 코팅, 고무, 도료, 플라스틱, 복합재료 등의 여러 분야에서 이용되어지며 PU를 전기방사 하여 얻은 부직포는 wound dressing, anti-bacteria mask, 인조 피혁, stent 등에 이용할 수 있을 것으로 기대된다. (중략)
