The surface and interface chemistry are critical for controlling the properties of two-dimensional transition metal carbides nitrides (MXenes). Numerous efforts have been devoted to functionalization MXenes with small inorganic ligands; however, few etching methods reported on direct bonding organic groups MXene surfaces. In this work, we demonstrated an efficient rapid strategy synthesis 2D Ti
Abstract Inspired by the application of nano‐fillers in composite materials, well‐dispersed aramid nanofibers (ANFs) were prepared and added into epoxy resin (EP) to improve toughness tenacity properties ANF/EP composites. The composites characterized mechanical property test, surface analysis, thermodynamic contact angle. Results showed that when EP was with 0.15 wt% ANF, tensile strength, bending impact strength are increased 28.2%, 81.9%, 81.8% compared pure EP, respectively. thermal...
To address the problem regarding poor shear resistance of commonly employed polymers for oil displacement, modified nano-SiO2/AA/AM copolymer (HPMNS) displacement agents were synthesized using acrylic acid (AA), acrylamide (AM), and nano-SiO2 different modification degrees as raw materials. HPMNS was characterized by means infrared spectroscopy (IR), nuclear magnetic resonance (1H-NMR, 13C-NMR), dynamic/static light scattering, scanning electron microscope. A comparative study properties...
Aramid fibers with low density and high strength, modulus, thermal resistance are widely used in applications such as bulletproof vests cables. However, owing to their chemical structure, they sensitive ultraviolet light, which degrades the fibers' useful mechanical properties. In this study, titanium dioxide (TiO2) nanoparticles were synthesized both on aramid III fiber surface interfacial space between fibrils/microfibrils supercritical carbon (scCO2) improve UV of fibers. The effects...
To improve a polymer's oil recovery power, it is imperative to discuss its residual resistance factor (RRF), which significant parameter in the field and associated with polymer molecular structure. This study investigated capability of three kinds hyperbranched polymers (HPDAs) various degrees branching establish RRF high permeability porous media by way one-dimensional sandpack model under different solution concentrations, permeabilities, injection rates. In addition, mechanisms these...

Abstract Aramid pulp (AP) is a highly fibrillated form of fiber， with excellent heat resistance, wear size stability, and other beneficial properties, that can be dispersed in rubber or resin matrix systems. Its fibrillation results large surface area. However, AP easily tangles aggregates between fibers because its Consequently, it experiences difficulty dispersing matrices, especially when relatively amount needed to mixed. In this study, SiO 2 nanoparticle was synthesized on the through...
Abstract Fluoride phase separation is the initial stage of nanocrystallization in oxyfluoride glasses, and it a key step achieving transparent glass‐ceramics with good luminescence. In this work, we combine molecular dynamics (MD) simulations experimental studies to investigate separation, photoluminescence fluoroaluminosilicate glass containing alkali earth fluoride (MF 2 ). The results reveal different behaviors due field strength difference M 2+ . composition size similarity between...
Abstract A new synthesis route was developed to produce the diamine monomer containing benzimidazole units, 6,4′‐diamino‐2‐phenylbenzimidazole (BIA), which easily prepared by reduction of 6,4′‐dinitro‐2‐phenylbenzimidazole synthesized via a reaction between 4‐nitro‐1,2‐phenylenediamine and 4‐nitrobenzoyl chloride. The composition structure products were confirmed Fourier transform infrared, NMR, elemental analysis. series polyimides polycondensation BIA various dehydrates, pyromellitic...
A histologic study of recombinant human bone morphogenetic protein-2/calcium phosphate cement (rhBMP-2/CPC) using adult rhesus monkeys in vivo.To evaluate the changes rhBMP-2/CPC vertebroplasty and determine feasibility this substitution instead polymethylmethacrylate (PMMA).Previous studies have shown that new rhBMP-2/nanoscale CPC has a suitable strength injection for vertebroplasty. However, osteoinductive properties biodegradable characteristics are still unclear.Percutaneous (PVP) was...
An excellent matching relationship in size exists between HPDA and the pore throat with a permeability reservoir of under 500–100 mD.
High modulus aramid fiber, such as Kevlar 49, is conventionally prepared by the heat annealing of high strength fiber under a suitable tension at temperature, especially higher than 500 °C. This enables mobility rigid molecule chain to be rearranged into more perfect crystalline or orientation structure tension. However, decreases tensile strength, since thermal degradation molecular temperature cannot avoided. 49 fibers treated in supercritical carbon dioxide (scCO2) could improve their...
