Graphene nanoplatelets (GNP) are used to produce wood plastic composites (WPC) with improved electrical and thermal conductivity. The polypropylene/wood/GNP hybrid produced by melt compounding followed hot pressing. effect of GNP loadings (5, 10 15 wt%) on conductivity, tensile properties, degradation WPC containing 20 wt% flour is studied. fast slow cooling rates during pressing the surface re...

Abstract Pristine carbon nanotubes (CNTs) and functionalized (f-CNTs) were introduced into conductive poly(methyl methacrylate)/graphene nanoplatelet (PMMA/GNP) composites to achieve a synergistic effect in the enhancement of conductivity reduction percolation threshold by forming 3-Dimensional(3-D) hybrid structure. Both in-plane perpendicular electrical properties investigated. The synergies ...

The tribological behaviour of diamond-like carbon (DLC) and graphene nanoplatelets (GNP) nanocomposite has not been previously explored in a lubricated environment, with some previous studies reporting only on materials the surface DLC. In this study DLC-GNP films various GNP coverages were synthesised by 3 step process: spin coating suspension, heat treatment, DLC deposition. study, effect cov...

During development, Sonic hedgehog (Shh) regulates the proliferation of cerebellar granule neuron precursors (GNPs) in part via expression of Nmyc. We present evidence supporting a novel role for the Mad family member Mad3 in the Shh pathway to regulate Nmyc expression and GNP proliferation. Mad3 mRNA is transiently expressed in GNPs during proliferation. Cultured GNPs express Mad3 in response ...

Homogeneous dispersion of graphene into thermoplastic polymer matrices during melt-mixing is still challenging due to its agglomeration and weak interfacial interactions with the selected matrix. In this study, an ideal within PA66 matrix was achieved under high shear rates by thermokinetic mixing. The flow direction monitored developed numerical methodology a combination rheological behaviors....

In this study, polyurethane (PU) was modified by direct mixing of carboxyl functionalised graphene (GNP–COOH) referred to as f-GNP, without using any solvent, during in-situ polymerization. a further attempt, the neat PU with f-GNP and hydrophobic silica-based solution (SG) The damping coefficient attenuation capacity (PU), based nanocomposite (PU + f-GNP), SG), together polytetrafluoroethylene...

Ultra-high molecular weight polyethylene (UHMWPE) is a relevant thermoplastic in industry and well-proven standard biomaterial joint replacements. To enhance its tribological properties while preserving bulk ones, composite coatings on UHMWPE substrate were prepared using non-functionalised graphene nanoplatelet (GNP) at reinforcement concentration of 0.1–5 wt% two mechanical mixing techniques ...
