Fine particles (PM 2.5 ) were collected using filter‐based high‐volume samplers during summer‐winter 2008 at a rural site in the central Pearl River Delta (PRD), south China, to determine typical secondary organic aerosol (SOA) tracers from significant biogenic (isoprene, monoterpenes, and sesquiterpenes) anthropogenic (aromatics) precursors. Average isoprene SOA significantly higher summer (126 ng m −3 than fall‐winter (25.1 ), owing largely emission reaction rates summer. monoterpene (11.6...
A facile method was developed to fabricate highly electrically conductive aramid fibers. The immobilization of silver nanoparticles on the surface polymetaphenylene isophthamide (PMIA) fibers carried out by functionalization PMIA with poly(dopamine), followed electroless plating. poly(dopamine) (PDA) layer deposited simply dipping substrate into an alkaline dopamine solution. ions can be chemically bound catechol and indole functional groups in PDA. were reduced using glucose as reducing...
By combining experiment and molecular simulation, in this work we have systematically elucidated the fundamental mechanism of significantly improved damping property nitrile-butadiene rubber (NBR) contributed by introduction hindered phenol (AO-80) small molecules. At level, through FTIR, 1H-NMR temperature-dependent it is observed that hydrogen bonds (H-bonds) interaction exists between AO-80 molecules NBR polymer chains, leading to formation a H-bonds network structure. Meanwhile, positron...
The improvement of modern electronics, which is constantly getting faster, has raised higher requirements for thermally conductive and electrically insulating thermal interface materials. Developing a facile universal processing method with high conductivity enhancement efficiency in pressing need to keep up this trend. Herein, we propose cost-effective foaming route construct the three-dimensional (3D) interconnected boron nitride (BN) network. Owing inspiration jelly, curdlan, an esculent...
In this work, the thermo-oxidative aging performance of antioxidant N-isopropyl-N′-phenyl-p-phenylenediamine (4010NA)/silica (SiO2)/natural rubber (NR) composite was evaluated by variations mechanical properties and chemical structure after at 100 °C. Compared with 4010NA/carbon black (CB)/NR composite, there existed significant synergistic effects between 4010NA SiO2 on improving stability NR material. Then, combining results experiments molecular simulations, stabilization mechanism in...
Abstract A novel class of polymers called “slide-ring” (SR) materials with slideable junctions were used for high damping composites the first time. The SR acts as phase dispersed in natural rubber (NR) matrix, and epoxidized (ENR) compatibilizer. morphological, structural, mechanical properties investigated by atomic force microscope (AFM), transmission electron (TEM), dynamic thermal analyzer (DMTA), processing (RPA), tensile tester. AFM TEM results showed that was uniformly composites, a...
Polyurethane (PU) has an excellent mechanical property due to its unique microphase separated structure, but the molecular mechanism is still unclear. In this work, a multiscale model and corresponding potential functions of PU are first developed via inverse Boltzmann iterative method. Following it, fracture toughness explored triaxial deformation, which exhibits rise with increase in content hard segments (HS). By analyzing stress decomposition, morphology, conformation two phases, HS...
In this work, a coarse-grained model is constructed to explore the structure, dynamics, and rheological behavior of associative polymers (APs) formed by hydrogen bonds (HBs). First, structural change HBs with number active groups temperature analyzed calculating bond length, angle, number, energy, strength HBs. Then, phase structure characterized analyzing size distribution clusters coordination per "hydrogen". Furthermore, dynamics polymer chains are calculated time correlation function...
Molecular dynamics (MD) simulations are used to investigate the fundamental damping mechanism of AO-60/nitrile-butadiene rubber (AO-60/NBR) composites at molecular level in this study. The hydrogen bonds (H-bonds), binding energy, and fractional free volume (FFV) AO-60/NBR were obtained. composite with an AO-60 content 36 phr had largest H-bonds, highest smallest FFV, all indicating a good compatibility between NBR performance composite. experimental FTIR, 1H-NMR results also showed that two...
Deoxynivalenol (DON) is one of the most common mycotoxins in grains, causing gastrointestinal inflammation, neurotoxicity, hepatotoxicity and embryotoxicity, even at a low quantity. In this study, facile electrochemical aptasensor was established for rapid sensitive determination DON based on multifunctional N-doped Cu-metallic organic framework (N–Cu–MOF) nanomaterial. The N–Cu–MOF, with large specific surface area good electrical conductivity, served not only as an optimal signal probe but...
Polylactic acid (PLA) has received increased attention in the development of shape-memory polymers and biomedical materials owing to its excellent physical properties good biocompatibility biodegradability. However, inherent brittleness high shape-recovery temperature this material limit application human body.
