With the rapid advancement of electronic technology, the demand for wearable and portable electronic devices has significantly increased. MXene-based multifunctional textiles have attracted extensive attention from researchers due to their unique various functionalities, while the poor oxidation and structure stability limit their applications. In this study, a novel MXene/tannic acid-modified cellulose nanofibers (TACNF)-based multifunctional textile was prepared by screen-printing and post treatment. The abundant phenolic hydroxyl groups in TA effectively protect the MXene nanosheets from oxidation. The subsequent ZnCl₂ cross-linking treatment leads to the metal coordination between Zn ions and TA molecules, which further improves the structure stability of the composite coating and endows the functional textile with enhanced antimicrobial activity against Escherichia coli and Staphylococcus aureus. The composite textile with a rationally designed electrically conductive structure demonstrates decent sensing ability toward tiny and large human motions, and its exceptional photo-/electro-thermal conversion ability also enables promising potential applications in thermal therapy and heat sterilization. This study provides new insights for the design and fabrication of smart healthcare textiles.

抗氧化 MXene/TA/纳米纤维素杂化油墨，用于抗菌性能增强的多功能智能纺织品丝网印刷


随着电子技术的飞速发展，对可穿戴和便携式电子设备的需求显着增加。MXene 基多功能纺织品因其独特的各种功能而受到研究人员的广泛关注，而较差的氧化性和结构稳定性限制了其应用。本研究通过丝网印刷和后处理制备了一种基于 MXene/单宁酸改性纤维素纳米纤维 （TACNF） 的新型多功能纺织品。TA 中丰富的酚羟基可有效保护 MXene 纳米片免受氧化。随后的 ZnCl₂ 交联处理导致 Zn 离子和 TA 分子之间的金属配位，这进一步提高了复合涂层的结构稳定性，并赋予功能性纺织品对大肠杆菌和金黄色葡萄球菌的增强抗菌活性。具有合理导电结构的复合纺织品对微小和大型人体运动表现出良好的传感能力，其卓越的光/电热转换能力也为热疗和热灭菌提供了广阔的潜在应用。本研究为智能保健纺织品的设计和制造提供了新的见解。
