Abstract

Public health emergency of international concern has greatly attracted consumers’ attention to textiles with sustainable personal health protection functions. Although there have been many valuable advances in the research of antibacterial textiles, there is still a slight lack of emphasis on the protective ability against fungi. Herein, an antimicrobial agent (CePO₄@Ag) composed of cerium phosphate (CePO₄) and silver nanoparticles (AgNPs) is reported. The antimicrobial agents and pigment are pre-dispersed using a green and facile masterbatch method, followed by melt spinning to produce colored PET multifunctional fibers. The synergistic effect between CePO₄ and AgNPs in the fibers not only ensures efficient silver ion release for antimicrobial activity but also utilizes the inherent antimicrobial properties of CePO₄, thereby achieving outstanding antifungal effects with inhibition rates exceeding 99%. Importantly, the PET multifunctional fibers maintained satisfactory color-indicating properties after the incorporation of CePO₄@Ag, possessing a tinctorial strength of 102.2%. Therefore, the fabricated PET fibers combine amazing antimicrobial, color-indicating properties, and substantial mechanical strength. This work provides a facile preparation method for the colored antimicrobial textiles.

磷酸铈和纳米银的协同作用增强了有色PET纤维的抗菌性能

国际关注的突发公共卫生事件极大地吸引了消费者对具有可持续个人健康防护功能的纺织品的关注。尽管抗菌纺织品的研究取得了许多有价值的进展，但对抗菌纺织品对真菌的保护能力的重视程度仍略显不足。本文报道了一种由磷酸铈（CePO4）和银纳米粒子（AgNPs）组成的抗菌剂（CePO4@Ag）。抗菌剂和色素采用绿色易溶母粒法预分散，然后熔融纺丝生产彩色PET多功能纤维。CePO4与AgNPs在纤维中的协同作用，既保证了银离子的高效释放抗菌活性，又利用了CePO4固有的抗菌特性，达到了抑菌率超过99%的优异抑菌效果。重要的是，在加入CePO4@Ag后，PET多功能纤维保持了令人满意的显色性能，着色强度达到102.2%。因此，制造的PET纤维结合了惊人的抗菌、显色性能和可观的机械强度。本工作为有色抗菌纺织品的制备提供了一种简便的方法。图形抽象

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
