Printable Nano carbon colloidal ink has fascinated great attention due to their exceptional potential for large-scale application for powering wearable electronic devices. Though, it is challenging to incorporate various characteristics together such as mechanical stability, solution printability, conductivity, electrocatalytic activity, and heat generating properties in the flexible fabric based electrode system. In this research the development of printable composites made with woven/nonwoven fabrics printed with multiwall carbon nanotubes for flexible and wearable heating system and cathodes for dye-sensitized solar cells (DSSC), respectively. We report a printable carbon ink of multiwall carbon nanotubes (MWCNT) synthesized by globular protein serum bovine albumin (BSA). BSA is amino-rich dispersant used to disperse MWCNT and generate tubular porous carbon matrix. High loading ratio of BSA increases the dispersing power of MWCNT and increased porosity of CNT matrix. The proposed Organic Nanocarbon ink (Organic NC) serve the pathways for electron transport leading to higher heat dissipation as the well high conductivity and electrocatalytic activity. It was interesting to reveal that different kinds of woven and nonwoven fabrics displayed exceptional thermal properties when DC voltage was applied. The heat generating properties were highly dependent on the type of fabric and conductive ink uptake. Our proposed Organic NC printed fabric system exhibited superior conductivity with 15-20 Ω resistivity and lower charge transfer resistance R = 2.69 Ω, demonstrated an 8% power conversion efficiency of DSSC. The proposed research paves the ways for solution printable high performance woven and nonwoven conductive and thermoelectric materials for wearable electronics.
基于纳米碳胶体墨水的打印技术由于其在为可穿戴电子设备供能方面的巨大应用潜力而备受关注。然而，将机械稳定性、溶液可打印性、导电性、电催化活性和产热性能等各种特性结合到基于柔性织物的电极系统中是具有挑战性的。在这项研究中，我们开发了基于编织/非编织织物的可打印复合材料，分别用于柔性和可穿戴加热系统的打印以及用于染料敏化太阳能电池（DSSC）的阴极。我们报告了一种由球状蛋白血清牛白蛋白（BSA）合成的多壁碳纳米管（MWCNT）的可打印碳墨水。BSA 是一种富含氨基酸的分散剂，用于分散 MWCNT 并生成管状多孔碳基质。BSA 的高负载比增加了 MWCNT 的分散能力和 CNT 基质的多孔性。所提出的有机纳米碳墨水（Organic NC）为电子传输提供了途径，从而导致更高的散热效率，同时还具有高导电性和电催化活性。有趣的是，当施加直流电压时，不同种类的编织和非编织织物显示出出色的热性能。产热性能高度依赖于织物和导电墨水的吸收量。我们提出的有机 NC 打印织物系统表现出优异的导电性，电阻为 15-20 Ω，电荷转移电阻 R 为 2.69 Ω，DSSC 的功率转换效率达到 8%。这项研究为可穿戴电子设备的高性能编织和非编织导电和热电材料的溶液可打印铺平了道路。
