近年來，電熱性紡織品發展受到很多關注，紡織與發熱元件的結合就成為智慧紡織領域研究重點。保暖紡織品則以紡織材料為設計基礎，使紡織紗線本身具有加熱保溫的功能。一般市面常見的電熱型產品系統，多以碳素纖維、電熱絲等為主體，再包含高純度的鎳系合金而成。然而電熱性紡織品許多問題需要克服，例如紡織與電熱絲相容性，動作時熱源穩定，材料環保性，舒適性等問題。
因此，在此研究，以碳黑、奈米碳管、石墨烯作為導體製作成主動發熱元件，以製作不同奈米碳材的電熱性薄膜作為研究目的，探討電熱性薄膜表面結構、導電性、導熱性、拉伸性、重複加熱性影響性。第一部分，由於奈米碳材容易於傾向聚集的行為，首先將設計及合成高分型分散劑(Polymeric Dispersant)幫助奈米碳材(Carbon black, CB/Carbon Nanotubes, CNTs/Reduced Graphene Oxide, rGO) 獲得良好的分散型態，此高分子行分散劑是以苯乙烯-馬林酸酐共聚物(SMA系列)和聚醚單胺( Polyoxyalkylene amine、M1000) 進行酰胺化和酰亞胺化反應合成，以奈米碳材與分散劑不同比例(1:0、1:0.5、1:1、1:1.5、1:2)，並以FT-IR、DLS與TEM分析其結果。第二部份，高分子分散劑使奈米碳材(CB,CNT)具備高穩定性且均勻分散溶液中，進一步添 
加具有彈性之聚氨酯(Polyurethane、PU)。使用奈米碳材(CB、CNT)添加還原氧化石墨烯(rGO)製備發熱薄膜，以奈米碳材與還原氧化石墨烯不同比例(2:1、1:1、1:2)做比較。添加還原氧化石墨烯有助於提升導電、導熱，拉伸和疲勞等機械性質，有助於奈米碳材(CB,CNT)均勻分散並彼此呈現互相連接的網絡結構型態，使複合薄膜形成導電網絡，可以提升導電性且具有良好穩定的熱電性能。以CNT/rGO比例1:1，膜厚100 μm最低電阻值為3.3x101 ohm/sq，施加電壓(9V)薄膜溫度上升至92.1℃，在應變量20%，具有良好的回復性。未來將可應用於保暖的智能產品上。

In recent years, the development of electrothermal textiles has received a lot of attention, and the combination of textile and heating elements has become the focus of research in the field of smart textiles. Warm textiles are based on textile materials, which make the textile yarn itself have the function of heating and heat preservation. Generally, the electrothermal product system commonly used in the market is mainly composed of carbon fiber, electric heating wire, etc., and further contains a high-purity nickel-based alloy. However, many problems of electrothermal textiles need to be overcome, such as the compatibility of textile and electric heating wire, the stability of heat source during operation, environmental protection of materials, and comfort.
Therefore, in this study, carbon black, carbon nanotubes, and graphene were used as conductors to form active heating elements, and electrothermal films of different nanocarbon materials were fabricated for research purposes. The surface structure and electrical conductivity of electrothermal thin films were discussed. Thermal conductivity, stretchability, and repeated heating properties.
The first part, due to the tendency of nanocarbon materials to tend to aggregate, the first design and synthesis of high-concentration dispersant (Carbon black, CB/Carbon Nanotubes, CNTs/Reduced Graphene Oxide, rGO) Obtaining a good dispersion pattern, the polymer dispersant is synthesized by amide reaction of Styrene Maleic Anhydride copolymer (SMA series) and Polyether monoamine (M1000). The results were  
analyzed by FT-IR, DLS and TEM in different ratios of nanocarbon material and dispersant (1:0, 1:0.5, 1:1, 1:1.5, 1:2).
The second part, the polymer dispersant makes the nanocarbon material (CB, CNT) stable and dispersed in the solution, Add polyurethane with elasticity (Polyurethane, PU). The heat-generating film was prepared by adding rGO using nanocarbon materials (CB, CNT), and comparing the ratio of nanocarbon material rGO to (2:1, 1:1, 1:2). The addition of rGO can improve the mechanical properties such as conduction, heat conduction, tensile and fatigue, and contribute to the uniform dispersion of nanocarbon materials (CB, CNT) and interconnected network structures so that the composite film is formed. The conductive network can improve conductivity and have stable thermoelectric performance. With a CNT/rGO ratio of 1:1, the minimum resistance of the film thickness of 100 μm is 3.3x101 ohm/sq, and the applied voltage (9V) film temperature rises to 92.1 °C, with a strain of 20%, and favorable recovery. The future will be applied to warm smart products.
