The use of conductive polymer composites (CPCs) for strain sensing applications has attracted intense interest lately. stability and sensitivity resistivity–strain behaviour are thought to be important issues, but systematic investigations missing. Herein, the behavior in terms CPCs based on poly(styrene-butadiene-styrene) (SBS) containing multiwalled carbon nanotubes (MWCNTs) studied. It is demonstrated that preparation method an influence these CPCs. Under linear uniaxial strain, increases...

Abstract Inorganic clay was investigated as a compatibilizer for immiscible poly(propylene)/polystyrene blends. A substantial decrease in the number of polystyrene particles seen after adding small amounts an organically treated (2–5 wt.‐%) to possible mechanism this kind compatibilization is discussed, but these unique and completely new findings need further verification. Schematic representation intercalated structure PP/PS/OMMT blends: (a) PP PS confined same gallery OMMT, (b) parts...

The formation of a nanohybrid shish-kebab (NHSK) superstructure, in which fibrillous carbon nanotubes (CNTs) act as shish while polymer lamellae kebab, is novel way to bond the and CNTs together was first observed solution crystallization polyethylene presence CNTs. In this work, direct injection molded bar high-density (HDPE)/multiwalled (MWCNTs) composite, has been achieved, via so-called dynamic packing molding technology (DPIM), oscillatory shear field imposed on gradually cooled melt...

In this work, a great synergistic effect of 2D clay platelets and 1D carbon nanotubes (CNTs) on reinforcing chitosan matrix has been observed for the first time. With incorporation 3 wt % 0.4 CNTs, tensile strength Young's modulus nanocomposites are significantly improved by about 171 124%, respectively, compared with neat chitosan. This could be understood as due to formation much jammed fillers network CNTs combined together, indicated rheological measurement. Our work demonstrates good...

Morphological control of conductive networks involves the construction segregated or double-percolated is often reported to reduce electrical percolation threshold polymer composites (CPCs) for better balance among conductivity, mechanical properties, and filler content. Herein, with both characteristics achieved based on polypropylene (PP)/polyethylene (PE) multi-wall carbon nanotubes (CNTs). CNTs were firstly dispersed in PE; then PE/CNTs compounded PP particles well below melting...

Abstract The fascinating two‐dimensional (2D) materials are being potentially applied in various fields from science to engineering benefitting the charming physical and chemical properties on optics, electronics, magnetism, compared with bulk crystal, while piezotronics is a universal pervasive phenomenon broking center symmetry, promoting new field notable achievements of 2D higher accuracy sensitivity. For example, 20 parts per billion detecting limitations NO 2 sensor, 500 μm spatial...

Strong and ductile adhesives often undergo both interfacial cohesive failure during the debonding process. Herein, we report a rare self-reinforcing polyurethane adhesive that shows different phenomenon of only yet still exhibiting superior strength toughness. It is synthesized by designing hanging moiety, hierarchical H-bond moieties, crystallizable soft segment into one macromolecular polyurethane. The former moiety allows hot-melt to effectively associate with target substrate, providing...

Succinate, traditionally viewed as a mere intermediate of the tricarboxylic acid (TCA) cycle, has emerged critical mediator in inflammation. Disruptions within TCA cycle lead to an accumulation succinate mitochondrial matrix. This excess subsequently diffuses into cytosol and is released extracellular space. Elevated cytosolic levels stabilize hypoxia-inducible factor-1α by inhibiting prolyl hydroxylases, which enhances inflammatory responses. Notably, also acts extracellularly signaling...

Abstract The development of graphene‐based responsive material has gained tremendous attention in recent decades and led to search for alternative 2D materials beyond graphene. In years, due their large surface‐to‐volume ratio, atomic thickness, excellent selectivity molecular adsorption, graphene, including hexagonal boron nitride, transition metal dichalcogenides, black phosphorus, MXenes, have exhibited great potential stimuli‐responsiveness. This review explores the five representative...

Polypropylene (PP)/montmorillonite (MMT) nanocomposites have been prepared by melt intercalation using organomontmorillonite and conventional twin screw extrusion. The dispersibility of silicate layers the montmorillonite in composites was investigated X-ray diffractometer transmission electron microscopy (TEM). are dispersed at nanometer level PP matrix, as revealed TEM results. tensile strength PP/MMT is not much improved compared with pure or filled composites. However, impact greatly...

Abstract By adding a small amount of clay into poly( p ‐phenylene sulfide) (PPS)/polyamide 66 blends, the morphology was found to change gradually from sea–island cocontinuity and lamellar supramolecular structure, as increasing content. Clay selectively located in PA66 phase, exfoliated layers formed an edge‐contacted network. The is not caused by volume ratio viscosity but can be well explained dynamic interplay phase separation between PPS through preferential adsorption onto layer–layer...
