It is widely believed that the trigonal β-form favorable and effective for toughening isotactic polypropylene (iPP). Therefore, content should be achieved as high possible to realize excellent toughness in iPP. However, this study, we demonstrate connection between crystallites might mainly determine of iPP instead β-crystal content. A new rare earth nucleator (WBG) was used generate rich β-crystalline structure compression-molded bars were fabricated upon different molten temperatures (Tf)....
In aiming to obtain highly flexible polymer composites with high dielectric performance, graphene/poly(vinylidene fluoride) (PVDF) a multi-layered structure were proposed and prepared. Graphene sheets prepared by reducing graphene oxide using phenylhydrazine, which could effectively alleviate aggregation of the sheets. A two-step method, including solution casting compression molding, was employed fabricate graphene/PVDF composites. The showed an alternative PVDF. Due their unique structure,...
PVDF/OH-BNNS nanocomposites show improved dielectric, thermal and mechanical properties through cooperation with surface hydroxylated BNNSs.
Recently, some attempts have been made to enhance the gas barrier properties of semicrystalline polymers by precisely controlling arrangement their impermeable crystalline lamellae. However, it is still a great challenge achieve regular lamellae along direction perpendicular diffusion path, especially using conventional polymer processing technologies. This work presents novel and simple strategy dramatically improve oxygen performance biobased biodegradable polylactide (PLA) through...
The environment-friendly fibers fabricated from natural polysaccharides have attracted much attention in the development of sustainable materials, owing to global pollution caused by and textiles petroleum-based polymers. Chitin derived seafood wastes possesses excellent biocompatibility biodegradability, but it is still far being fully explored. Here, we designed prepared, for first time, chitin with nanofibril structures solution NaOH/urea aqueous system cooling on a lab-scale wet-spinning...
Cellulose nanopaper is a strong lightweight material made from renewable resources with wide range of potential applications, membranes to electronic displays. Most studies on target high mechanical strength, which compromises ductility and toughness. Herein, we demonstrate the fabrication highly ductile tough cellulose via fibrillation hemicellulose-rich wood fibers dispersion obtained nanofibrils (CNFs) in an ionic liquid (IL)–water mixture. This treatment allows hemicellulose swelling,...
We report on the formation of water-in-water liquid crystal emulsions with permeable colloidal assemblies. Rodlike cellulose nanocrystals (CNC) spontaneously self-assemble into a helical arrangement coexistence nonionic, hydrophilic polyethylene glycol (PEG) and dextran, whereas two polymer solutions are thermodynamically incompatible. Stable easily prepared by mixing respective CNC/polymer solutions, showing micrometric CNC/PEG dispersed droplets continuous CNC/dextran phase. With time,...
Abstract As part of a continuous effort to develop high performance isotactic polypropylene (iPP) based on β‐form crystalline and morphological change induced by rare earth nucleator (WBG), various WBG contents (from 0.025 1.0 wt%) were adopted prepare β‐nucleated iPP at fixed final molten temperature (240°C) in this study. The crystallinity, polymorphic composition, morphology inspected detail series crystallographic characterizations, including calorimeter, X‐ray diffraction, polarized...
Abstract Patterned micro/nanomaterials display efficient light management capabilities owing to their control of propagation within multiscale periodic structures. Here a hierarchical photonic structure composed polystyrene microspheres and cholesteric assembly cellulose nanocrystals is described, acting as polarization‐sensitive retroreflective coating microlens array. Micropatterned films are prepared by casting an aqueous nanocrystal suspension onto monolayer substrate through...

Abstract Polytetrafluoroethylene (PTFE) receives wide attention in electronic packaging materials due to its excellent dielectric properties, friction properties and thermal stability. However, extremely low conductivity limits further application. In this work, hexagonal boron nitride (h‐BN) platelets are added into PTFE matrix improve the as expense of largely deteriorated property. To make up loss property, alumina particles (AO) also effects filler ratio between h‐BN on tribological...
Triboelectric nanogenerators (TENG) have great potential to help enhancing the energy efficiency of buildings, and thus contribute significantly reduction global greenhouse gas emissions. However, there are major barriers against adoption such emerging technologies. Meeting need for sustainable large-scale fabrication high-performance products remains a critical challenge towards real-world TENGs' building applications. To mitigate this challenge, we enhance poor polarizability native wood...
