Superhydrophobic cotton fabrics with improved ultraviolet resistance were prepared via in situ growing NH2-MIL-125(Ti)(Ti-MOF) nanoparticles on cotton fibers and subsequently coating with polydimethylsiloxane (PDMS) under room temperature. The synergetic effect of Ti-MOFs nanoparticles and PDMS was critical and essential for obtaining a superhydrophobic coating with anti-UV property. The surface microstructure,...
Highly efficient and reusable photocatalysts that enable photodegradation of pollutants under visible light is the key in waste water treatment with impacts on environment and sustainable development. In this article, we report the preparation and application of a novel core–shell photocatalyst of bismuth vanadate@polydopamine (BiVO4@PDA). The optical absorption property and microstructure of the...
Bletilla striata polysaccharide (BSP) extracted from B. striata tuber, which is a traditional Chinese medicine, is used for preparing a fiber with mechanical properties through the environment-friendly method of phase inversion with ethanol as the nonsolvent. The prepared BSP fiber is woven into fabric with excellent flexibility, overcoming the considerable hardness of BSP membranes. The proposed...
Depositing anisotropic noble metal nanoparticles with high uniformity and yield on flexible substrates is the determining factor for surface enhanced Raman spectroscopy (SERS) detection. In this work, flexible, durable and sensitive SERS substrates were fabricated by in situ reduction of Ag nanoparticles on polydopamine templated cotton fabrics (CF) as catalytic hotspots to enhance the following deposition...
A durable antibacterial and superhydrophobic viscose textile has been developed via in situ growing silver nanoparticles (NPs) on tannic acid (TA)-coated viscose textiles and further hydrophobic treatment under mild reaction condition. The surface morphology and chemical composition of the modified textile have been characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy,...
Nanofibers based on natural polymers have recently been attracting research interest as promising materials for use as skin substitutes. Here, we prepared photocrosslinked nanofibrous scaffolds based on methacrylated chitosan (MACS) by photocrosslinking electrospun methacrylated chitosan/poly (vinyl alcohol) (PVA) mats and subsequently removing PVA from the nanofibers. We comprehensively investigated...
