近红外响应型多功能三聚氰胺泡沫的制备及其抗菌、电磁屏蔽性能研究
NIR-triggered photothermal antibacterial melamine foam decorated by MXene/AgNWs with integrated electromagnetic interference shielding for potential bacterial infection
摘要
Abstract
Chronic rhinosinusitis(CRS),often complicated by detection of Staphylococcus aureus(S.aureus)pathogens,poses a significant clinical challenge to conventional treatment methods.Meanwhile,the electromagnetic interference(EMI)and radiation concerns have caused potential threats to not only wearable medical device functionality but also to human health.Herein,a multifunctional melamine foam(MF)composite is developed for efficient bacterial eradication,which is fabricated through integrating Ti3C2Tx MXene and Ag nanowires(AgNWs)onto melamine foam skeleton,followed by encapsulation with a polydimethylsiloxane(PDMS)layer to increase the biocompatibility and self-cleaning property.The resulting melamine foam/MXene/AgNWs/PDMS(MMAP)composite exhibits outstanding photothermal conversion under near-infrared(NIR)irradiation.When combined with the sustained release of Ag⁺ ions,excellent antibacterial action against S.aureus with 99.86%sterilization rate was achieved.Simultaneously,the interconnected MXene/AgNWs network confers excellent electrical conductivity and and EMI shielding effectiveness of 30.1 dB.This study offers a potential method for designing integrated bio-materials that combine electromagnetic shielding,photothermal bactericidal activity and self-cleaning property,offering potential applications in preventing bacterial related infections,as well as suppressing EM radiation.关键词
