Recently, highly conductive polymer nanocomposites, particularly soft polymer nanocomposites, have received extensive attention as promising material candidates for wearable devices. Compared with the cases of the wearable devices based on conventional rigid electronic materials, the wearable devices based on polymer nanocomposites exhibit excellent conformal contacts with the skin due to the soft mechanical properties of these nanocomposites; therefore, soft polymeric nanocomposites can be applied to stretchable wirings, electrodes, and sensor units in various on-skin electronics. The types of polymers and nanofillers used for the synthesis of these nanocomposites are critical factors determining the properties of polymer nanocomposites. The overall physical properties of nanocomposites depend on the type of polymer used, whereas the electrical properties of nanocomposites are governed by the type of nanofiller employed. Herein, we review the latest studies on the polymer nanocomposites constructed using different polymers and nanofillers that are applied to wearable devices. We have classified the polymers into non-elastic polymers, hydrogels, chemically crosslinked elastomers, and physically crosslinked elastomers and the nanofillers into C, liquid metal, Ag, Au, and other emerging nanomaterials. Detailed characteristics, fabrication methods, applications, and limitations of these nanocomposites are reviewed. Finally, a brief outlook for future research is provided.

可拉伸导电纳米复合材料及其在可穿戴设备中的应用

最近,高导电聚合物纳米复合材料,特别是软聚合物纳米复合材料,作为可穿戴设备的候选材料受到了广泛关注。与基于传统刚性电子材料的可穿戴设备相比,基于聚合物纳米复合材料的可穿戴设备由于这些纳米复合材料的柔软机械性能而表现出与皮肤良好的共形接触;因此,软聚合物纳米复合材料可应用于各种皮肤电子产品中的可拉伸布线、电极和传感器单元。用于合成这些纳米复合材料的聚合物和纳米填料的类型是决定聚合物纳米复合材料性能的关键因素。纳米复合材料的整体物理性质取决于所用聚合物的类型,而纳米复合材料的电性能取决于所用纳米填料的类型。在此,我们回顾了使用不同聚合物和纳米填料构建的聚合物纳米复合材料的最新研究,并将其应用于可穿戴设备。我们将聚合物分为非弹性聚合物、水凝胶、化学交联弹性体和物理交联弹性体,将纳米填料分为碳、液态金属、银、金等新兴纳米材料。综述了这些纳米复合材料的详细特性、制造方法、应用和局限性。最后,对未来的研究进行了简要展望。我们回顾了使用不同的聚合物和纳米填料构建的聚合物纳米复合材料的最新研究,这些聚合物应用于可穿戴设备。我们将聚合物分为非弹性聚合物、水凝胶、化学交联弹性体和物理交联弹性体,将纳米填料分为碳、液态金属、银、金等新兴纳米材料。综述了这些纳米复合材料的详细特性、制造方法、应用和局限性。最后,对未来的研究进行了简要展望。我们回顾了使用不同的聚合物和纳米填料构建的聚合物纳米复合材料的最新研究,这些聚合物应用于可穿戴设备。我们将聚合物分为非弹性聚合物、水凝胶、化学交联弹性体和物理交联弹性体,将纳米填料分为碳、液态金属、银、金等新兴纳米材料。综述了这些纳米复合材料的详细特性、制造方法、应用和局限性。最后,对未来的研究进行了简要展望。审查了这些纳米复合材料的应用和局限性。最后,对未来的研究进行了简要展望。审查了这些纳米复合材料的应用和局限性。最后,对未来的研究进行了简要展望。
