Two-dimensional (2D) organic materials hold great promise for use in a multitude of contemporary applications due to their outstanding chemical and physical properties. Herein, 2D sheets poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) are prepared from commercially available PEDOT:PSS suspension using ice as template. The grow the boundaries crystals polymers "squeezed" out when water solidifies. mechanical robustness can be enhanced by incorporating WO3 nanowires, PSS...
Electrocatalysis is critical to the performance displayed by sulfur cathodes. However, constituent electrocatalysts and reactants have vastly different molecular sizes, which ultimately restrict electrocatalysis efficiency hamper device performance. Herein, authors report that aggregates of cobalt single-atom catalysts (SACs) attached graphene via porphyrins can overcome challenges associated with catalyst/reactant size mismatch. Atomic-resolution transmission electron microscopy X-ray...
Red phosphorus (RP) is a promising anode material for use in lithium-ion batteries (LIBs) due to its high theoretical specific capacity (2596 mA h g–1). However, the practical of RP-based anodes has been challenged by material's low intrinsic electrical conductivity and poor structural stability during lithiation. Here, we describe phosphorus-doped porous carbon (P-PC) disclose how dopant improves Li storage performance RP that was incorporated into P-PC (designated as RP@P-PC). P-doping...
Despite significant progress in the preparation and characterization of two-dimensional (2D) materials, synthesis 2D organic materials remains challenging. Here, we report a novel space-confined polymerization method that enables large-scale sheets functional conjugated polymer, namely, poly(3,4-ethylenedioxythiophene) (PEDOT). A key step this is confinement monomer to boundaries ice crystals using micelles. This spatial directs form PEDOT with high crystallinity controlled morphology....
The significant disparity between the compressive and tensile strengths of carbon fiber reinforced polymer (CFRP) composites restricts their widespread application. Designing developing epoxy resin matrix materials with high strength modulus is crucial for improving performance composites. Here, carbonyl groups are introduced into molecules as hydrogen bond receptors, a novel trifunctional glycidyl ester TAEP successfully synthesized. construction dense network achieves remarkably strength....
Lithium–sulfur (Li–S) batteries have attracted extensive attention due to the high theoretical specific capacity of sulfur (1675 mA h g–1). Despite advantage, utility Li–S is limited by low electrical conductivities and its discharge products (i.e., Li2S2 Li2S) as well "shuttle effect" polysulfides. Herein, a strategy covalently grafting sulfur-containing polymers carbon nanotubes (CNTs) proposed solution problems associated with cathodes. The are grafted CNTs using an "inverse...
Lithium-sulfur (Li-S) batteries hold great promise for widespread application on account of their high theoretical energy density (2600 Wh kg-1 ) and the advantages sulfur. Practical use, however, is impeded by shuttle effect polysulfides along with sluggish cathode kinetics. it reported that such deleterious issues can be overcome using a composite film (denoted as V-CMP@MWNT) consists conjugated microporous polymer (CMP) embedded vanadium single-atom catalysts (V SACs) network multi-walled...
Nonradiative (NR) processes are pivotal in engineering materials with tailored properties for energy utilization. However, their intrinsic rapidity and competitiveness pose huge challenges on‐demand manipulation. Herein, radical‐assisted multiple NR were achieved to couple photothermy photosensitization based on a unique near‐infrared‐absorbing diradical‐featured croconium (CR) dendrimer, CR‐(DPA)2‐OMe. This dendrimer is well‐designed by the direct covalent linkage between flexible dendritic...

Polyurethane (PU) nanofibers were prepared from electrospun method. Atomic force microscopy (AFM) was employed to characterize the mechanical properties of PU nanofibers. The impact temperature on behavior studied using three-point bending test based AFM. A Young's modulus ~ 25 GPa obtained for with diameter at 150 nm room temperature. With decrease in nanofiber's diameter, increasing can be due surface tension effect. nanofiber decreased linearly while fibrous morphology maintained increase
Research on structural-functional integration of polymers has become an inevitable trend and development orientation in modern materials science. An intrinsic flame-retardant epoxy with superior mechanical properties reusability is great application value as a composite matrix structural material.

It is attractive and realistic to construct deformable, recyclable, high-performance adaptive structural materials. In this paper, a novel method was presented improve the deformability of traditional epoxy resins by topological design at molecular level. Conformational transformation cross-linked networks facilitated grafting rigid side groups onto backbone, which can also be achieved in multicomponent with low group concentration. The conformational evolution enables achieve multiple...
