“…The coating of PDVB on modified nonwoven fabrics was achieved with one‐step reaction with the synthesis of PDVB. The cationic polymerization reaction, which employed DVB as monomer and BFEE as initiator, was conducted to obtain PDVB nanofibres . Before the reaction, the modified nonwoven fabrics were added into 80 mL n ‐hexane, and then 240 μL BFEE was also added.…”

“…Among them, polydivinylbenzene (PDVB), a kind of novel superhydrophobic material, has been attracting considerable attentions because of its high specific surface area, hollow structure and high cross‐linking degree, which were favourable to the adsorption of many pollutants in environment . Although the possibility of oil adsorption by PDVB has been confirmed, recent studies focused mainly on the synthesis method of PDVB, painting PDVB onto different surfaces, and its usage as cross‐linkers . Moreover, PDVB was generally synthesized by a solvothermal method, which takes a long time and needs complex conditions at high temperature in the presence of nitrogen .…”

Background Oil pollution of water causes extensive damage to the environment and human health. Adsorption techniques are environmentally friendly and relatively feasible to treat oil contamination and reclaim oil resources, and it is essential to develop adsorbents that have high adsorption capacity for oil which can be recycled and regenerated conveniently to save money and resources. Results Hydrophobic nonwoven fabrics coated with polydivinylbenzene nanofibres (HNF‐PDVB) were constructed by a one‐step cation polymerization reaction. The results showed that the optimal concentration of OTS (octadecylsilane) for the modification of nonwoven fibers was 1.22 mL L–1of n‐hexane. The HNF‐PDVB showed relatively good performance in adsorbing oil from water, with adsorption capacity as high as 7.5 g g–1. Freundlich and Dubinin–Radushkevic isotherms fitted well with the experimental data. The kinetic data fitted better to the pseudo‐second‐order and intraparticle diffusion models, and the parameters indicated that the adsorption by HNF‐PDVB involved macropores that contributed to the rapid and high‐capacity adsorption, as well as micropores that resulted in the diffusion of oil in the nanofibres. Thermodynamics studies revealed that the adsorption was spontaneous and endothermic, with an increasing performance when the temperature rose from 10 to 50 °C. The material possessed good stability and the adsorption capacity reduced from 7.5 g g–1 to 6.6 g g–1 after ten cycles of repeated use, recovered by squeezing and ethanol extraction. Conclusion This work demonstrates that the new hydrophobic nonwoven fabrics have the potential to be used for elimination of pollution from oil wastewater. © 2018 Society of Chemical Industry

“…In our previous report on the synthesis of poly(DVB-co-VBC) nanotubes in cyclohexane, it is difficult to achieve nanotubes or nanofibers when the DVB content is at low levels [27] . It is understandable that cyclohexane is a good solvent for linear poly(VBC).…”

We herein report a novel approach to fabricate poly(DVB-co-VBC) one-dimentional nanomaterials with varied composition. By adjusting the monomer DVB/VBC ratio and using inert solvents, after internal cavity of the nanotubes disappears and length of the nanotubes is decreased, thus nanorods are achieved. After quaternary ammoniation from the benzyl chloride group, the exterior surface becomes hydrophilic while the interiority preserves hydrophobic. The Janus nanorods can serve as a specific vehicle to selectively collect oils from their aqueous surroundings.

“…However, 1D nanostructures as stimuli responsive nano-objects have rarely been addressed. Thus, combining the favorable pH or temperature dependent properties of stimuli-responsive polymers with the unique characteristics of 1D polymer nanostructures makes it possible for external switching and manipulation when applied to drug delivery [11,12], electronic/optical devices [13], separations [14,15] and catalyst supports [16]. Furthermore, the incorporation of metal nanoparticles (NPs) into stimuli-responsive 1D polymer acidic environment while deswell under neutral to basic condition.…”
