Abstract
With the rapid development of flexible wearable strain sensor systems, electronic textiles with comfort and controllable strain/pressure-sensing capabilities have attracted great interest. However, it is still a great challenge to prepare multifunctional wearable strain/pressure sensor with an ultra-low detection limit through a facile and cost-effective method. Here, conductive carbon nanotubes modified silk nonwoven fabric (CNTs/SNWF) composite was successfully prepared by the surface micro-dissolution and adhesion technology (SD&AT). Micromorphology analysis showed that CNTs were adhered firmly on the surface of silk fiber to form an effective conductive network. The conductive CNTs/SNWF-based strain/pressure sensor can detect a strain as low as 0.05% and an ultralow pressure of 10 Pa, showing an ultrahigh discernibility. Besides, it also exhibited excellent sensing stability and reproductivity under different conditions, making it applicable in the field of real-time human movement monitoring. Moreover, electronic skin was also established based on the conductive CNTs/SNWF to recognize different tactile stimulus. Interestingly, the prepared conductive CNTs/SNWF also displayed great applicability for optical and thermal sensing, endowing it with more functionality for next-generation wearable electronics.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
