本論文主要目的為以靜電紡絲法製備聚氨酯(Polyurethane, PU)奈米纖維薄膜，經由製程可以得到質量輕、具彈性，同時擁有高比表面積的纖維薄膜；但PU屬於絕緣性的高分子材料，因此我們利用不同維度的碳材加以表面改質及纖維混紡，形成導電高分子纖維薄膜，運用在智慧衣感測元件量測人體訊號。
本研究分為兩部份，第一部份利用靜電紡絲法先製備聚氨酯奈米纖維薄膜，再於表面塗佈利用自行合成的星形油溶性高分子分散劑分散過後的碳黑(Carbon Black，CB)、石墨烯溶液，利用高比表面積的特性充分吸附碳材，並透過碳材本身的立體結構與尺寸大小之差異特性，由微米/奈米分散及聚集現象可以模仿荷葉表面的結構，以提高薄膜表面的粗糙度及疏水性質，使其達到超疏水的性質，並同時透過碳材本身的導電性可以增加其導電的性能。
第二部份同樣以靜電紡絲的方式來製成奈米纖維薄膜，將利用分散劑分散好的碳黑、石墨烯溶液混入較低濃度的PU中，直接進行單軸的靜電紡絲，形成導電高分子纖維薄膜，加以與表面塗佈形成的導電薄膜做比較，探討其加工方式不同對薄膜所形成的導電度、疏水特性及其機械及熱性質做比較。
從實驗結果顯示，此薄膜的疏水角度可達150度以上，同時表面電阻小於1000歐姆；此薄膜不僅擁有PU本身的彈性及輕薄特性，同時改變了其絕緣的性質，使之能夠成功的製備出人體感測的電極層材料可應用於智慧衣上，並有效的使用在心電圖(Electrocardiogram, ECG)來量測人體訊號。

The main purpose of this study is to prepare for making polyurethane (PU) nanofiber film by electrospinning method. The fiber membrane with high specific surface area can be obtained in the process. PU is an insulating polymer material and therefore we use different dimensions of carbon materials to modify surface and blend them into fiber. The formation of conductive polymer fiber film is used in the sensor components to measure body signals.
This study is divided into two parts. The first part is the preparation of polyurethane nanofiber thin film by electrospinning method. The surface is coated solution using star oil-soluble polymer dispersant dispersed carbon black (Carbon Black, CB), Graphene in toluene. We put the fiber film into dispersed CB/PML solution, and then the micron / nano dispersion and aggregation phenomenon can mimic the structure of the lotus leaf surface to improve the roughness and hydrophobicity of the film surface. In addition, it can increase electrical conductivity through the carbon materials.
In the second part, the carbon nanofiber film is prepared by electrospinning. The carbon black solution dispersed with the dispersant is mixed into the low concentration of PU, and directly form the conductive Polymer film. It thereby is compared with the conductive film formed by surface coating in terms of conductivity, hydrophobicity and its mechanical and thermal properties.
The experimental results show that the hydrophobic angle of the film can reach more than 150 degrees, while the surface resistance is less than 1,000 ohms. This film not only has flexibility of the PU and is also very light. Therefore, it can be successfully used in human sensing electrode materials owing to the change to its feature of insulation. Furthermore, it can be applied to the smart clothes using electrocardiogram to measure body signals.
