Abstract Poly(ϵ‐caprolactone) (PCL)/layered double hydroxide (LDH) nanocomposites were prepared successfully via simple solution intercalation. The nonisothermal melt crystallization kinetics of neat PCL and its LDH was investigated with the Ozawa, Avrami, combined Avrami–Ozawa methods. Ozawa method failed to describe studied systems. Avrami found be useful for describing behavior, but parameters in this do not have explicit meaning crystallization. explained behavior effectively. kinetic...
Abstract Analysis of the nonisothermal melt and cold crystallization kinetics poly(aryl ether ketone ketone) (PEEKK) was performed by using differential scanning calorimetry (DSC). The Avrami equation modified Jeziorny could describe only primary stage PEEKK. And, Ozawa analysis, when applied to this polymer system, failed its behavior. A new convenient approach for proposed combining with equation. By evaluating kinetic parameters in approach, behavior PEEKK analyzed. According Kissinger...
Multiwalled carbon nanotubes (MWNTs)/nylon-6 (PA6) nanocomposites with different MWNTs loadings have been prepared by the simple melt-compounding approach. A fine and homogeneous dispersion of throughout PA6 matrix is observed transmission electron microscopy. Scanning microscopy observation on fracture surfaces composites shows not only a uniform but also strong interfacial adhesion matrix, as evidenced presence many broken strongly embedded (CNTs) in absence debonding CNTs from matrix....

Abstract High-entropy alloys have received considerable attention in the field of catalysis due to their exceptional properties. However, few studies hitherto focus on origin outstanding performance and accurate identification active centers. Herein, we report a conceptual experimental approach overcome limitations single-element catalysts by designing FeCoNiXRu (X: Cu, Cr, Mn) system with various sites that different adsorption capacities for multiple intermediates. The electronegativity...
The development of biomass-based energy storage devices is an emerging trend to reduce the ever-increasing consumption non-renewable resources. Here, nitrogen-doped carbonized bacterial cellulose (CBC-N) nanofibers are obtained by one-step carbonization polyaniline coated (BC) nanofibers, which not only display excellent capacitive performance as supercapacitor electrode, but also act 3D bio-template for further deposition ultrathin nickel-cobalt layered double hydroxide (Ni-Co LDH)...
Graphene oxide (GO) sheets, considered as "soft" two-dimensional macromolecules containing multiple aromatic regions and hydrophilic oxygen groups, can adsorb the pristine multiwalled carbon nanotubes (MWNTs) through π-stacking interaction, thus causing MWNTs to stably disperse fractionate in aqueous media. The water-soluble insoluble complexes be obtained by changing initial proportion of GO which are important for noncovalent approaches toward solubilizing CNTs open a new way applications...
Polyaniline hollow spheres (PANI-HS)@electrochemical reduced graphene oxide (ERGO) hybrids with core–shell structures have been fabricated via a solution-based coassembly process. The nanostructured designing for the PANI-HS greatly enlarges specific surface area, providing high electroactive regions and short diffusion lengths both charge ion transport. wrapping of ERGO sheets on can offer highly conductive pathways by bridging individual together, thus facilitating rate cycling performance...
Abstract Long-term stability and high-rate capability have been the major challenges of sodium-ion batteries. Layered electroactive materials with mechanically robust, chemically stable, electrically ironically conductive networks can effectively address these issues. Herein we successfully directed carbon nanofibers to vertically penetrate through graphene sheets, constructing robust nanofiber interpenetrated architecture. Molybdenum disulfide nanoflakes are then grown in situ alongside...
An electronegativity-dominant high-entropy atomic environment regulation strategy was developed to manipulate the electrocatalytic properties by tailoring competitive adsorption sites in HEA NPs.
Abstract The development of energy storage devices that can endure large and complex deformations is central to emerging wearable electronics. Hydrogels made from conducting polymers give rise a promising integration high conductivity versatility in processing. However, the emergence polymer hydrogels with desirable network structure cannot be readily achieved using conventional polymerization methods. Here we present cryopolymerization strategy for preparing an intrinsically stretchable,...

Hollow polyaniline (PANI) nanofibers with controllable wall thickness are fabricated by in situ polymerization of aniline using the electrospun poly(amic acid) fiber membrane as a template. A maximum specific capacitance 601 F g(-1) has been achieved at 1 g(-1), suggesting potential application hollow PANI for supercapacitors. The superior electrochemical performance is attributed to their structure, thin thickness, and orderly pore passages, which can drastically facilitate ion diffusion...
