Abstract

Increasing mechanical properties without losing electrical properties is of great importance for the development of advanced electronic textile products and their use in different areas. In this study, a cost-effective and facile preparation of MXene/cellulose nanocrystal-coated cotton fabrics by drop-casting was carried out to investigate electrical and mechanical properties of plain woven cotton fabrics. MXene (Ti₃C₂T_x) and cellulose nanocrystal dispersions of MXene (5 wt.%, 10 wt.% and 15 wt.% cellulose nanocrystal content) were applied to cotton fabrics, and the coated fabrics were characterized in terms of their morphological and structural properties for their suitability for wearable electronics. The surface resistivity and mechanical properties were also determined to evaluate the effectiveness of coating. Ti₃C₂T_x/cellulose nanocrystal dispersions are suitable to obtain a low electrical resistivity (186.4 Ω/sq) in cotton fabrics. The results also showed that increasing cellulose nanocrystal content results in a more stable coating layer on the cotton fabric and a high tensile (63.2 MPa) and elongation at break values are obtained (30.2%) as a result of that.

用于可穿戴电子设备的 MXene/纤维素纳米晶体涂层棉织物电极

在不损失电气性能的前提下提高机械性能对于先进电子纺织产品的开发及其在不同领域的应用具有重要意义。在本研究中，我们采用滴注法制备了 MXene/纤维素纳米晶体涂层棉织物，研究了平纹棉织物的电气和机械性能，该方法成本低、操作简便。将 MXene（Ti3C2Tx）和 MXene 的纤维素纳米晶分散体（纤维素纳米晶含量分别为 5 wt.%、10 wt.% 和 15 wt.%）涂覆到棉织物上，并对涂覆织物的形态和结构特性进行表征，以确定其是否适用于可穿戴电子设备。同时还测定了表面电阻率和机械性能，以评估涂层的有效性。Ti3C2Tx/纤维素纳米晶体分散体适合在棉织物中获得较低的电阻率（186.4 Ω/sq）。结果还显示，纤维素纳米晶体含量的增加会使棉织物上的涂层更加稳定，从而获得较高的拉伸值（63.2 兆帕）和断裂伸长率（30.2%）。
