Abstract
Abstract Antibacterial fibers have great potential in many applications, such as medical dressings, surgical sutures and masks, etc. owing to their good growth inhibition against bacteria. However, for the fabrication of antibacterial fibers, the traditional inorganic nanoparticles coating method shows the disadvantages of high cost, low stability and binding fastness. Herein, we develop a facile, scalable and cost-effective blend spinning strategy to fabricate the highly effective antibacterial zeolitic imidazolate framework-8@alginate (ZIF-8@SA) fibers through wet spinning of the mixture of ZIF-8 and SA. The fabricated ZIF-8@SA fibers show high antibacterial efficiency, good durability and high tensile strength. The antibacterial performance of ZIF-8@SA fibers is superior to the most reported inorganic nanoparticles modified fibers. The excellent antibacterial performance of ZIF-8@SA fibers is attributed to the reactive oxygen species from the ZIF-8 and the swelling of SA. This work may shed light on the antibacterial mechanisms of metal organic frameworks and pave the way for the development of high-performance, durable and highly effective antibacterial textiles.

Bacterial infection is one of the top ten leading causes of death globally and the worst killer in low-income countries. The overuse of antibiotics leads to ever-increasing antibiotic resistance, posing a severe threat to human health. Recent advances in nanotechnology provide new opportunities to address the challenges in bacterial infection by killing germs without using antibiotics. Antibiotic-free antibacterial strategies enabled by advanced nanomaterials are presented. Nanomaterials are cla...

Abstract Facile construction of multifunctional fabrics with durability still remains a challenge in the past decade. In this work, we report a facile fabrication of non-fluorinated superhydrophobic and antibacterial cotton fabric surfaces via in situ growing zeolitic imidazolate framework-8 (ZIF-8) nanocrystals on cotton fibers under room temperature condition and subsequently coating with polydimethylsiloxane (PDMS). The surface morphology and chemical composition of treated fabric have been c...

Abstract In this work, surface metallization of cotton fabrics was performed by electroless plating using a shorter route than is conventional. The fabric surface was activated by deposition of silver and copper nanoparticles, and then a thin layer of copper was coated using electroless plating. The performance of coated fabrics was compared in terms of electrical conductivity, electromagnetic interference (EMI) shielding, Joule heating and antibacterial properties with another sample coated wit...

Silver nanoparticle (AgNP) and AgNP/reduced graphene oxide (rGO) nanocomposite impregnated medical grade polyviscose textile pads were formed using a facile, surface-mediated wet chemical solution-dipping process, without further annealing. Surfaces were sequentially treated in situ with a sodium borohydride (NaBH4) reducing agent, prior to formation, deposition, and fixation of Ag nanostructures and/or rGO nanosheets throughout porous non-woven (i.e., randomly interwoven) fibrous scaffolds. The...

Silica sols modified with a silver compound are applied onto textile substrates to realize its antibacterial properties. As textile substrates, cotton fabrics are used. The liquid sol recipes are applied by a padding process onto the textiles. Afterwards, a microwave-assisted heating process is applied for drying of the silica sol coating and to form elementary silver nanoparticles. The microwave process is done in a closed autoclave system with process temperatures in the range of 80–140 °C. Th...

Abstract Utilization of nanoparticles has increased significantly over last decade due to their extraordinary properties they offer. They are being used extensively in all fields including textiles but the biggest constraints of nanoparticles in textiles is their non-durability. One way to address this issue is the surface functionalization of nanoparticles for increasing their adhesion with textiles. Titanium dioxide (TiO2) has been used for making self-cleaning fabrics. In this study, TiO2 nan...
