The effect of morphology on poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene)-based soft actuators: Films and electrospun aligned nanofiber mats

چکیده
This paper analyzes soft actuators realized as unimorph cantilever beams, in which the active layer can have two different morphologies, i.e., either an extruded film or aligned electrospun nanofiber mat of poly(vinylidene fluoride-trifluoroethylene-chlorotrifluoroethylene). Six are fabricated, with layers varying thicknesses and to study electrostrictive effect polymer evaluate stiffening properties, mechanical work, blocking forces when stimulated by direct current electric fields. The comparison between is performed introducing weight specific stiffness showing improved properties for nanofibers-based actuators. Moreover, forces, tip deflections, leakage currents evaluated alternating experiments show faster viscoelastic relaxation lower electrical power consumption concludes that, thank its electro-mechanical fluoride-trifluoroethylene-chlorotrifluoroethylene) form has high potential be used beam

Magnetoelectric CoFe2O4/polyvinylidene fluoride electrospun nanofibres.
Magnetoelectric 0-1 composites comprising CoFe2O4 (CFO) nanoparticles in a polyvinylidene fluoride (PVDF) polymer-fibre matrix have been prepared by electrospinning. The average diameter of the electrospun composite fibres is ∼325 nm, independent of the nanoparticle content, and the amount of the crystalline polar β phase is strongly enhanced when compared to pure PVDF polymer fibres. The piezo...
متن کاملLysozyme-loaded, electrospun chitosan-based nanofiber mats for wound healing.
In this study, a blend mixture of chitosan-ethylenediaminetetraacetic acid (CS 2 wt%-EDTA) at a weight ratio of 30/70 and polyvinyl alcohol (PVA) solution (10 wt%) was electrospun to produce fibrous mats with lysozyme (10, 20 and 30 wt%) used for wound healing. The morphology and diameter of the electrospun fiber mats with and without lysozyme were analyzed by scanning electron microscopy (SEM)...
متن کاملElectrospun chitosan-based nanofiber mats loaded with Garcinia mangostana extracts.
The aim of this study was to prepare electrospun chitosan-based nanofiber mats and to incorporate the fruit hull of Garcinia mangostana (GM) extracts into the mats. Chitosan-ethylenediaminetetraacetic acid/polyvinyl alcohol (CS-EDTA/PVA) was selected as the polymers. The GM extracts with 1, 2 and 3 wt% α-mangostin were incorporated into the CS-EDTA/PVA solution and electrospun to obtain nanofib...
متن کاملPolyvinylidene fluoride–trifluoroethylene as a reservoir for absorbed water
The absorption of water in Langmuir–Blodgett fi lms of ferroelectric copolymers of polyvinylidene fl uoride with trifl uoroethylene is shown to depend upon the fi lm thickness. This water absorption can have a profound effect on the dielectric properties of the copolymer fi lms.
