制造具有紫外线防护的Janus纳米粒子功能化织物,强度增强,自清洁性能,和洗涤耐久性,具有生物相容性,在现代功能面料工程中至关重要。特别是,定制能够表现出几种不同性质的多功能纳米粒子,利用低成本原材料,坚持绿色化学原则至关重要。开发多功能反应性Janus纳米粒子的制造策略,利用废物衍生的天然多酚(槲皮素-3-葡糖苷酸,杨梅素-3-半乳糖苷,gossypin,Phlorizin,山奈酚,杨梅素-3-阿拉伯糖苷)-整合的锌-二氧化硅核-壳Janus纳米粒子,具有紫外线防护,强度增强,和自清洁特性,是提议的。多酚被用作合成锌-多酚配合物的可持续前体,然后将其包封在二氧化硅壳中以形成核-壳结构。此外,Janus颗粒是通过引入具有半胺/羧酸和半甲基末端的双功能层而产生的,赋予反应性亲水和疏水特性。涂有Janus涂层的纺织品和皮革对有害的紫外线辐射表现出显着的衰减,与水接触角测量确认改进的防水性。材料中天然酚类和双官能团的共存增强了纺织强度,培养优越的附着力和显着增强洗涤耐久性。这种环保的方法,利用废物衍生材料,为可持续纺织工程提供了一个有前途的解决方案,具有增强的防紫外线和防水性能,从而促进绿色纳米技术在纺织应用中的发展。
Fabricating Janus nanoparticle-functionalized fabrics with UV protection, strength enhancement, self-cleaning properties, and wash durability, with a biocompatible nature, is crucial in modern functional fabrics engineering. Particularly, tailoring multifunctional nanoparticles capable of exhibiting several distinct properties, utilizing low-cost raw materials, and adhering to green chemistry principles is pivotal. A fabrication strategy for developing multifunctional reactive Janus nanoparticles, utilizing waste-derived natural polyphenol (quercetin-3-glucuronide, myricetin-3-galactoside, gossypin, phlorizin, kaempferol, myricetin-3-arabinoside)-integrated zinc-silica core-shell Janus nanoparticles with UV protection, strength enhancement, and self-cleaning properties, is proposed. Polyphenols were utilized as sustainable precursors for synthesizing zinc-polyphenol complexes, which were then encapsulated within a silica shell to form a core-shell structure. Furthermore, Janus particles were created by introducing a bifunctional layer with half amine/carboxylic acid and half methyl terminals, imparting reactive hydrophilic and hydrophobic properties. Janus-coated textiles and leather exhibited significant attenuation of harmful UV radiation, with water contact angle measurements confirming improved water repellency. The coexistence of natural phenols and bifunctional groups within a material bolstered textile strength, fostering superior adhesion and markedly enhancing wash durability. This eco-friendly approach, utilizing waste-derived materials, presents a promising solution for sustainable textile engineering with enhanced performance in UV protection and water resistance, thereby contributing to the advancement of green nanotechnology in textile applications.
