Using “3D-spacer” technology, we have knitted 80% β-phase PVDF with Ag/PA66 fibres to demonstrate all fibre piezoelectric power generators. The 3D structure provides a density of 1.10–5.10 μW cm<sup>−2</sup>at applied impacts 0.02–0.10 MPa.
Piezoelectric materials have been in use for many years; however, with an increasing concern about global warming, piezoelectricity has gained significant importance research and development extracting energy from the environment. In this work voltage responses of ceramic based piezoelectric fibre composite structures (PFCs) polymer strips, PVDF (polyvinylidene fluoride), were evaluated when subjected to various wind speeds water droplets order investigate possibility generation these two...
Self-polarised poly(vinylidene fluoride), (PVDF), films were prepared via a facile phase-inversion technique wherein the polymorphism of was controlled from exclusive α- (>90%) to β-phase (>98%) by simply varying quenching temperature 100 °C -20 °C, respectively. At low temperatures, crystallites found be self-aligned, with PVDF thin possessing high piezoelectric coefficient up -49.6 pm V(-1). The extraordinarily and these make them suitable for electroactive energy harvesting applications.
Polymers have been widely used as piezoelectric materials in the form of films and bulk but there are limited publications on fibre structures. In this paper process preparing polyvinylidene fluoride (PVDF) fibres from granules by continuous melt extrusion in-line poling is reported for first time. The PVDF was carried out at an extension ratio 4:1, a temperature 80 C high voltage order 13 000 V 0.5 mm diameter extruder. entire making them to make using customized prepared were then tested...
Self-polarized Gd5Si4-polyvinylidene fluoride (PVDF) nanocomposite films have been synthesized via a facile phase-inversion technique. For the 5 wt% Gd5Si4-PVDF films, enhancement of piezoelectric β-phase and crystallinity are confirmed using Fourier transform infrared (FTIR) spectroscopy (phase fraction, Fβ, 81% as compared to 49% for pristine PVDF) differential scanning calorimetry (crystallinity, ΔXc, 58% 46% PVDF), respectively. The Gd5Si4 magnetic nanoparticles, prepared high-energy...
Functionalization of Polytetrafluoroethylene (PTFE) powders ~6 μm particle size is carried out using low-pressure 2.45 GHz H2, NH3 microwave plasmas for various durations (2.5, 10 h) to chemically modify their surface and alter energy. The X-ray Photoelectron Spectroscopy (XPS) analyses reveal that plasma treatment leads significant defluorination (F/C atomic ratio 1.13 1.30 h H2 treatments, respectively vs. 1.86 pristine PTFE), along with the incorporation functional polar moieties on...
The monograph critically reviews most commonly used geotextile structures, their properties and performance characteristics. In general, both natural synthetic fibres are for the production of geotextiles, advantages disadvantages each type fibre discussed various applications geotextiles. important functions i.e. filtration, drainage, separation reinforcement have been identified related to several major Various properties, namely mechanical, hydraulic chemical test methods discussed. A...
In recent years, textile based wound dressing products have grown from simple gauze to smart dressings with considerable technical and commercial impact. Today, are manufactured a large variety of different materials applied in all phases healing. this study, commercially available were investigated compared vitro. The tested evaluated vary their components structures basically fell into three main groups: nonwoven, foam hydroactive products. This study analysed the properties 13 dressings:...
In this paper, electromagnetic shielding effectiveness (EMSE) of needle-punched nonwoven fabric produced from silver-coated staple polyamide fibre having a fineness 1.7 dtex was investigated. This production carried out at Automatex needle punching line, which consists carding, cross lapper and machine. After production, the surface resistivity measurements in accordance with ASTM D 257-07 standard. The EMSE as-produced determined using network analyzer as specified D4935-10 frequency range...
