本研究設計新型三款聚異丁烯-醯亞胺(PIB-imide-PIB)高分子型分散劑，來比較奈米銀粒子的穩定，顯示PIB-ED2003-PIB對奈米銀粒子具有良好的穩定性，隨後添加零維材料及一維材料的有機/無機混成分散劑來穩定奈米銀粒子的探討。使用市售化碳黑及奈米碳管為分散劑，因碳黑及奈米碳管大多由多芳香族所組成，較為親油性，有良好的導電性。其中奈米銀粒子可經由有機高分子型分散劑及碳材以非共價作用力吸附而達到奈米分散及穩定，並進一步將分散液均勻塗佈/混合至高分子基材上及經過加熱程序，最終可以獲得高導電之薄膜材料(表面電阻約10-2 Ω/sq)。並利用聚醯亞胺薄膜(Polyimide ; PI)以及熱塑性彈性體(Thermoplastic Elastomer ; TPE)製備出軟性電極層與具可拉伸電極層並應用於智慧衣感測元件上。
本研究成功製備出高導電奈米複合薄膜，此薄膜是藉由塗佈有機/無機奈米銀混成材料而來，其中奈米銀粒子經由有機材料為高分子型分散劑、無機材料為奈米碳黑及奈米碳管以非共價作用力吸附而達到分散及穩定，並進一步將分散液塗佈及加熱程序，最終可以獲得高導電之薄膜材料並成功量測出心電圖。

We compare the stability of silver nano particles by using three types of PIB-imide-PIB polymer dispersant. The results come out that PIB-ED2003-PIB has great stability to silver nano particles. Then we add organic/inorganic hybrid dispersant contain zero-dimensional and one-dimensional material inside the dispersant, and study the stability of silver nano particles. We use carbon black and carbon nano tube as dispersant, because they have aromatic group, carbon black and carbon nano tube are hydrophobic and have great conductivity. In the experiment, silver nano particles can be nano dispersion and stability because of the non-covalent force of carbon material and organic polymer dispersant. We then coat the dispersions onto polymide with thermoplastic elastomer to make flexible electrode and stretchable electrode which can be applied to Sensing element of smart textile.
We sucessfully prepare high conductivity nano composite film by coating organic/inorganic nano silver blending material. The silver nano particles we use was prepare by adding polymer dispersant as organic materials, and carbon black and carbon nano tube as inorganic materials to make silver nano particles dispersed and stable. Then we coat the dispersions onto polymer substrate and process heating. Finally we make high conductivity film and sucessfully measured ECG.
