The paper, titled “Self-charging, antibacterial, and biodegradable functional materials prepared by electrospinning: for masks, wound dressings, and vascular grafts,” presents a novel composite nanofiber material developed based on electrospinning technology. SZTU is listed as the first author affiliation, the primary completing unit, and the first corresponding unit.

Notably, Luo Yuchao, an undergraduate student from the Class of 2026, the Future Technology School, is the paper’s first author. Co-first authors include Hu Yingjie (a joint-training master’s student) and Peng Tianyi (a laboratory technician). The corresponding authors are Prof. Liu Qingxia and Assistant Prof. Chen Zhixiang.

The research team developed a versatile nanofiber material with significant application potential in respiratory protective masks, wound dressings, and vascular grafts. The composite fiber membrane demonstrates stable self-charging performance, with filtration efficiency and duration surpassing those of commercial materials. An Ag@PLA layer provides excellent antibacterial properties, effectively inhibiting Escherichia coli and drug-resistant Staphylococcus aureus, while maintaining outstanding biodegradability and environmental safety.

In wound healing experiments, the material accelerated tissue repair and suppressed infections. Its unique porous structure promotes nutrient penetration and cell infiltration, supporting cell growth and showing promise for vascular graft applications. This multifunctional nanofiber material offers an innovative solution for next-generation biomedical materials, addressing critical healthcare challenges with broad clinical applicability.
