Effect of melt and solution electrospinning on the formation and structure of poly(vinylidene fluoride) fibres. Issue 29 (21st March 2017) - Asai, Hanako
Abstract : Linear laser melt electrospinning and conventional solution electrospinning. Abstract : We investigated the effects of applied voltage and collector rotating speed on the crystal structure and piezoelectricity of poly(vinylidene fluoride) (PVDF) fibres obtained by two electrospinning (ES) systems; laser-melt electrospinning (M-ES) and conventional solution electrospinning (S-ES). A higher β phase fraction was observed in the S-ES fibres, although the M-ES fibres showed comparable crystallinity. The piezoelectric constant ( d 33 ) for the S-ES fibres was also higher than that of the M-ES fibres. This is the first report clarifying the difference between M-ES and S-ES for the formation of PVDF fibres.
