Fabrication of hydrophilic and hydrophobic site on polypropylene nonwoven for removal of bisphenol a from water: explorations on adsorption behaviors,mechanisms and configurational influence

In this study, hydrophilic and hydrophobic site was fabricated onto the surface of polypropylene (PP) nonwoven for removal of bisphenol A (BPA). The adsorption behaviors as well as the adsorption driving forces were systematically analyzed. It is revealed that the amphiphilic PP nonwoven (PP-g-GMA-OA) had strong affinity towards BPA molecules and the predominant driving forces were hydrophobic interaction and hydrogen bonding. The hydrophobic site acted as adsorption site to provide hydrophobic interaction. The hydrophilic site accelerated the diffusion and adsorption process. In addition, the detailed connections between grated layer configuration and adsorption behaviors were observed and systematically elucidated. To ascertain the configurational transformation of grafted layer on PP surface, a microparticle grafting experiment was designed based on stimuli-responsive material measurement and the results indicated that the grafted layer had extended and contracted configuration with the variety of pH. Surface zeta potential measurement revealed that the configurarational transformation was mainly controlled by electrostatic interaction. On the basis of specially designed adsorption isotherm experiment, it is observed that extended configuration could offer more sites and slightly increased the adsorption capacity compared with contracted configuration.     

具有抗菌性能的新型载银细菌纤维素纳米纤维(英文)

In this work, we describe a novel facile method to prepare long one-dimensional hybrid nanofibers by using hydrated bacterial cellulose nanofibers（BCF） as a template. Silver（Ag） nanoparticles with an average diameter of 1.5 nm were well dispersed on BCF via a simple in situ chemical-reduction between AgNO3 and NaBH4 at a relatively low temperature. A growth mechanism is proposed that Ag nanoparticles are uniformly anchored onto BCF by coordination with BC-containing hydroxyl groups. The bare BCF and as-prepared Ag/BCF hybrid nanofibers were characterized by several techniques including transmission electron microscopy, X-ray diffraction, thermogravimetric analyses, and ultraviolet-visible（UV-Vis） absorption spectra. The antibacterial properties of Ag/BCF hybrid nanofibers against Escherichia coli（E. coli, Gram-negative） and Staphylococcu saureus（S. saureus, Gram-positive） bacteria were evaluated by using modified Kirby Bauer method and colony forming count method. The results show that Ag nanoparticles are well dispersed on BCF surface via in situ chemical-reduction. The Ag/BCF hybrid nanofiber presents strong antibacterial property and thus offers its candidature for use as functional antimicrobial agents.

Flexible and Highly Conductive AgNWs/PEDOT:PSS Functionalized Aramid Nonwoven Fabric for High-Performance Electromagnetic Interference Shielding and Joule Heating

High-performance multifunctional textiles are highly demanded for human health-related applications. In this work, a highly conductive nonwoven fabric is fabricated by coating silver nanowires (AgNWs)/poly(3,4-ethyl enedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) on a poly(m-phenylene isophthalamide) (PMIA) nonwoven fabric through a multistep dip coating process. The as-prepared PMIA/AgNWs/PEDOT:PSS composite nonwoven fabric shows an electrical resistance as low as 0.92 ± 0.06 Ω sq⁻¹ with good flexibility. The incorporation of the PEDOT:PSS coating layer improves the adhesion between AgNWs and PMIA nonwoven fabric, and also enhances the thermal stability of the composite nonwoven fabric. Electromagnetic interference (EMI) shielding and Joule heating performances of the PMIA/AgNWs/PEDOT:PSS composite nonwoven fabric are also investigated. The results show that the average EMI shielding effectiveness (SE) of the single-layer nonwoven fabric in X-band is as high as 56.6 dB and retains a satisfactory level of SE after being washed, bended, and treated with acid/alkali solution and various organic solvents. The composite nonwoven fabric also exhibits low voltage-driven Joule heating performance with reliable heating stability and repeatability. It can be envisaged that the multifunctional PMIA/AgNWs/PEDOT:PSS nonwoven fabric with reliable stability and chemical robustness can be used in EMI shielding devices and personal thermal management products.
