Abstract

An innovative Janus-structured self-healing composite engineered through multiscale design principles synergizes molecular-level dynamic bonding with macroscopic functional architectures, resolving the persistent challenge of balancing mechanical robustness (43.48 MPa tensile strength, 1185 % elongation) and autonomous repair capability. The composite system uniquely integrates triboelectric energy harvesting (1.89 mW/m² power density) with multifunctional performance metrics critical for advanced engineering applications: antimicrobial efficacy (96.98 % against E. coli, 97.88 % against S. aureus), UV shielding (UPF 1086.2), and antioxidant retention (93.3 %). Leveraging advanced interface engineering techniques, we demonstrate scalable manufacturing of Janus-type structures enabling concurrent biomechanical energy conversion and biological protection mechanisms. In conclusion, the self-healing wearable device based on the multi-functional Janus has sustainability and environmental friendliness and has broad application potential in the fields of collecting environmental energy, biosensors, and self-powered antibacterial.

PCLA-Janus工程摩擦电膜：用于可穿戴系统的集成能量收集和多模态传感的室温自修复复合材料

一种创新的双面结构自修复复合材料通过多尺度设计原理将分子级动态键与宏观功能结构协同起来，解决了平衡机械稳健性（43.48 MPa抗拉强度，1185%伸长率）和自主修复能力的长期挑战。该复合系统独特地集成了摩擦电能量收集（1.89 mW/m2功率密度）和对先进工程应用至关重要的多功能性能指标：抗菌效果（对大肠杆菌的抑菌率为96.98%，对金黄色葡萄球菌的抑菌率为97.88%），紫外线屏蔽（UPF 1086.2）和抗氧化保留（93.3%）。利用先进的界面工程技术，我们展示了可扩展制造的janus型结构，可以同时实现生物力学能量转换和生物保护机制。综上所述，基于多功能Janus的自修复可穿戴设备具有可持续性和环境友好性，在环境能源收集、生物传感器、自供电抗菌等领域具有广阔的应用潜力。

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
