Abstract

With the development of artificial intelligence and human-machine interaction technology, achieving all-nanofiber self-powered electronic skin (e-skin) with excellent sensing performance is still a challenge. In this work, polyvinylidene fluoride/polydimethylsiloxane (PVDF/PDMS) nanofiber membranes (PVPD-NFM) were prepared by optimizing the electrospinning humidity parameters. It is determined that when the humidity is 60 %, the roughness of the PVPD-NFM is 7.562 μm, and the content of β-phase is 64 %. After that, the content of PDMS was optimized. Compared with pure PVDF, when the content of PDMS was 42 wt%, the charge density increased from 1.6 μC/m² to 13.7 μC/m², which increased by 8.6 times, respectively. Furthermore, PVPD-NFM also possesses excellent breathability, hydrophobicity, and self-cleaning properties. Finally, the PVPD-NFM was fabricated into e-skin to detect muscle activity in fitness, indicating a promising application prospect in preventing sports injury.

采用静电纺湿控结构的全纳米纤维自供电电子皮肤，用于健身时人体肌肉检测

随着人工智能和人机交互技术的发展，实现具有优异传感性能的全纳米纤维自供电电子皮肤（e-skin）仍然是一个挑战。本文通过优化静电纺丝湿度参数，制备了聚偏氟乙烯/聚二甲基硅氧烷（PVDF/PDMS）纳米纤维膜。结果表明，当湿度为60%时，PVPD-NFM的粗糙度为7.562 μm， β相含量为64%。然后对PDMS的含量进行优化。与纯PVDF相比，当PDMS含量为42 wt%时，电荷密度由1.6 μC/m2提高到13.7 μC/m2，分别提高了8.6倍。此外，PVPD-NFM还具有优异的透气性、疏水性和自清洁性能。最后将PVPD-NFM制作成电子皮肤，用于检测健身过程中的肌肉活动，在预防运动损伤方面具有广阔的应用前景。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
