Barium titanate/polydimethylsiloxane nano/microcomposites fabrication, morphology, dielectric response and functionality

open access: yesIET Nanodielectrics, 2020
Polymer matrix composites with embedded ferroelectric and/or piezoelectric particles, constitute a novel and interesting class of engineering materials. The incorporation of ferroelectric and/or piezoelectric particles within a polymer matrix is expected

Starch‐capped sulphur nanoparticles synthesised from bulk powder sulphur and their anti‐phytopathogenic activity against Clavibacter sepedonicus

open access: yesIET Nanobiotechnology, 2021
Water‐soluble, stable nanoparticles of elemental sulphur with a size of 9‐52 nm have been synthesised using the stabilising potential of starch. Sulphide anions were used as sulphur precursors that were generated earlier from the bulk powder sulphur in ...

Capillary Filling of Polymer Chains in Nanopores

open access: yesMacromolecules, 2023
We performed molecular dynamics simulations with a coarse-grained model to investigate the capillary filling dynamics of polymer chains in nanopores. Short chains fill slower than predicted by the Lucas-Washburn equation but long chains fill faster. The analysis shows that the combination of the confinement effect on the free energy of chains and the ...

Tracking, erosion and thermal distribution of micro-AlN + nano-SiO(2) co-filled silicone rubber for high-voltage outdoor insulation

open access: yesHigh Voltage, 2018
Thermal depolymerisation induced tracking and erosion of polymeric insulators is one of the key insulation failure modes and this process adversely affects the reliability of power delivery networks.

Polymer-Filled Aquamarine

open access: yesGems & Gemology, 2009
The authors have encountered hundreds of polymer-filled aquamarines in the Chinese jewelry market. This treatment can be identified with a standard gemological microscope, since it has characteristics such as a flash effect and relief lines. In addition, some of the filled fractures fluoresce chalky white to long-wave UV radiation.

Regulating dielectric performances of Poly(vinylidene fluoride) nanocomposites by individually controlling shell thickness of Core@Double‐Shells structured nanowires

open access: yesIET Nanodielectrics, 2021
The synthesis of core@double‐shells structured TiO2@C@SiO2 nanowires (NWs) with variable thickness of carbon inner shell and SiO2 outer shell was achieved by individually controlling the chemical vapour deposition time and amount of silicon precursor ...

Mineral-filled Polymers [PDF]

open access: yes, 2001
The use of mineral fillers increases continuously. The incorporation of the filler into the polymer results in new materials. The properties of these composites are determined by the characteristics of the components, composition, interfacial interactions and structure.
