Aramid based on poly (p‐phenylene terephthalamide) (PPTA) is widely concerned as high‐performance materials. Herein, copolymerized aramid nanofibers (CANFs) were prepared for the first time by a direct bottom‐up polymerization method without additives. Three kinds of third monomers of m‐phenylenediamine, 4,4′‐diaminodiphenyl ether, and 2,5‐dichloro‐1,4‐phenylenediamine were separately copolymerized in PPTA and transformed into nanofiber dispersions in water medium. The characterization results revealed the relationship between the morphology of products and the structure as well as dosages of the different kinds of monomers, which was explained by the influence on conjugate regularities of the PPTA molecules. Furthermore, CANFs were used to build aramid paper blended in pure PPTA nanofibers, and the mechanical and insulation properties of composite paper were improved significantly, which would be of potential use as the new building block for aramid composite materials.

“…With the rapid development of industry, various environmental pollution problems become increasingly outstanding; especially the pollution of water by heavy metal ions, bacteria, and organic dyes. Heavy metal ions are nonbiodegradable, they accumulated in the biosphere and further entered into organism through the food chain, and organic dyes in wastewater created water pollution and even harm human health, whereas bacteria such as Staphylococcus aureus and Escherichia coli are main source of various diseases in human, all of these have posed enormous threat to ecological environment and human health. Therefore, kinds of technologies have been developed to handle these water pollutions, including adsorption, filtration, flocculation, chlorination, and photochemical disinfection .…”

Monolithic porous copolymers with 3D structure were prepared via CO 2 -in-water high internal phase emulsions template by graft copolymerization of sodium methacrylate (MAANa) on to methyl cellulose (MC) backbone. The yielded copolymer monoliths are characterized by Fourier transform infrared spectra, scanning electron microscopy (SEM), and mechanical instrument, the swelling degree of MC-g-PMAANa monoliths with different crosslinker in diverse pH were investigated. The adsorption performance of monolith to Cu(II) were conducted to explore its adsorption capacity to heavy metal ions from the wastewater. Then, a strategy of in situ growth of metal-organic frameworks (MOFs) on MC-g-PMAANa that adsorbed with metal ions was proposed first.The X-ray powder diffraction, SEM, and Brunauer-Emmett-Teller (BET) surface area result of MC-g-PMAANa/MOFs composites indicated that the MOFs nanoparticles were grown uniformly on the monolith wall without destroying its original 3D porous structure. Compared with MOFs nanoparticle, MC-g-PMAANa/MOFs composites have advantages of easy operation and handle, which more conform to practical application. Furthermore, the antibacterial activity of MC-g-PMAANa/MOFs was evaluated by disk agar diffusion and optical density methods. In addition, MC-g-PMAANa/Cu-BTC composite was applied to dye adsorption, which has proved the underlying application of such composites in dye removal.

“…Water contaminations by diverse kinds of organic pollutants, such as the endocrine disruptors from plastic manufacture, dyeing wastewaters, and antibiotic used in cultivation industry, have led to severe environmental and human health problems [1][2][3][4][5][6][7]. In recent years, peroxymonosulfate (PMS)based Fenton-like reactions have shown great potential to be utilized to generate reactive radicals for the degradation of organic pollutants in wastewater [8,9].…”

HIGHLIGHTS • Metal-organic-framework-derived carbon hybrids with elaborated nanostructures were prepared via N-molecule-assisted self-catalytic carbonization process. • The enriched Fe/Fe-N x /pyridinic-N active species, porous structures, and conductive carbon nanotubes can synergically augment the intrinsic catalytic activities. ABSTRACT To overcome the ever-growing organic pollutions in the water system, abundant efforts have been dedicated to fabricating efficient Fenton-like carbon catalysts. However, the rational design of carbon catalysts with high intrinsic activity remains a long-term goal. Herein, we report a new N-molecule-assisted self-catalytic carbonization process in augmenting the intrinsic Fenton-like activity of metalorganic-framework-derived carbon hybrids. During carbonization, the N-molecules provide alkane/ammonia gases and the formed iron nanocrystals act as the in situ catalysts, which result in the elaborated formation of carbon nanotubes (in situ chemical vapor deposition from alkane/iron catalysts) and micro-/meso-porous structures (ammonia gas etching). The obtained catalysts exhibited with abundant Fe/Fe-N x /pyridinic-N active species, micro-/meso-porous structures, and conductive carbon nanotubes. Consequently, the catalysts exhibit high efficiency toward the degradation of different organic pollutions, such as bisphenol A, methylene blue, and tetracycline. This study not only creates a new pathway for achieving highly active Fenton-like carbon catalysts but also takes a step toward the customized production of advanced carbon hybrids for diverse energy and environmental applications.
