We developed a book-shaped triboelectric nanogenerator (TENG) that consists of electrospun polyvinylidene fluoride (PVDF) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanofibers to effectively harvest mechanical energy. The dispersed graphene oxide in the PVDF acts as charge trapping sites, which increased interface for storage well output performance TENG. TENG was used direct power source drive small electronics such LED bulbs. This study proved it is possible improve TENGs...
Luminescent graphene quantum dots (GQDs) have been capped onto the nanopores of mesoporous silica nanoparticles (MSNs) through an acid-cleavable acetal bond. Herein, GQDs behave as dual-purpose entities that act capping agents and also exhibit excellent photoluminescence property.
Mechanical energy harvesting is a green technology with great potential for applications in self-powered portable electronics, wireless sensing, implanted devices, and security systems. We have previously reported triboelectric nanogenerator (TENG) fabricated from poly(vinylidene fluoride) (PVDF) electrospun nanofibers. This device enabled of mechanical exhibited an output voltage 210 V. Here we report doping the PVDF nanofibers silica (SiO2) nanoparticles, which increased performance...
A kind of novel acrylic resin denture base enhanced by PMMA-modified hydroxyapatite (M-HAP) was prepared and the modification effect HAP on mechanical properties material investigated in present study. whiskers were hydrothermal homogeneous precipitation process silanized coupling agent, 3-methacryloxy propyl trimethoxyl silane (γ-MPS), to induce vinyl groups onto its surface. Methyl methacrylate (MMA) then modified outside functionalized via polymerization build a similar chemical structure...
A one-step method of in situ polymerization nylon 66/reduced graphene oxide (PA66/rGO) nanocomposites is first proposed, simply by introducing (GO) into PA66 salt with the existence ammonium hydroxide. The GO prereduced hydroxide at an early stage process and then grafted on chains, accompanied thermal reduction GO. chains were onto nanosheets through condensation between oxygen-containing functional groups terminal amino ends chains. effect mechanical properties, especially tensile...
Dry‐jet‐wet‐electrospinning (DJWE) was carried out to study the formational mechanism of poly(hydroxybutyrate‐co‐hydroxyvalerate) electrospun fibers. Morphological comparison between normal electrospinning (NE) and DJWE investigated. The results showed that jet could solidify quickly in avoid bead collapse or fiber coherence. Jet structures be maintained at very low collection distance. Beanpod‐like beads, which were named as primary seen boundary stability instability section divided into...
Abstract Polymers of the 3-hydroxybutyrate-co-3-hydroxyvalerate type are ideal systems for study spherulite morphology. The growth spherulites was studied using polarizing microscopy with heat-stage and scanning electron (SEM). Some concentric ring features on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) PHBV were observed. SEM photos proved that rings occur surface spherulite. And it's a “Z”-shape feature, outer is higher than inner. factors influence phenomenon include temperature,...
Zwitterion functionalisation is carried out to alter surface properties and hence disperability of carbon nanotubes by attaching short long alkyl hydrocarbon chains onto the nanotubes. Long chain attachment results in term stabilisation toluene, whereas simply enhances their dispersion. Small angle light scattering used measure dispersion suspended toluene. Analysis these data elucidates mechanism which assists ultimately leads Functionalised untreated exhibit hierarchical morphology...
