Improved uniaxial dielectric properties in aligned diisopropylammonium bromide (DIPAB) doped poly(vinylidene difluoride) (PVDF) nanofibers

Abstract

Diisopropylammonium bromide (DIPAB) doped poly(vinylidene difluoride) (PVDF) nanofibers (5, 10 and 24 wt% DIPAB doping) with improved and tunable dielectric properties were synthesised via electrospinning.

A Review of Piezoelectric PVDF Film by Electrospinning and Its Applications

“…Other additives. Bhuga et al introduced another additive to enhance the β-phase PVDF polymer by mixing diisopropyl ammonium bromide (DIPAB) [ 122 ]. By analyzing samples with different concentrations of DIPAB (5, 10, and 24 wt.%), it was discovered that with the addition of 5 wt.% additive, the relevant dielectric constant of PVDF polymer increased from 8.5 to 102.5.…”

Facile preparation of high loading filled PVDF/BaTiO3 piezoelectric composites for selective laser sintering 3D printing

“… 20 But such polymers cannot satisfy the needs of practical applications due to their low piezoelectric strain constant and conversion efficiency. 21 Piezoelectric ceramics, featuring high piezoelectric constant, figure of merit, Curie temperature and stability, are currently the most applied piezoelectric materials, 22 such as lead zirconate titanate (PZT), barium titanate (BaTiO 3 ), etc. 23,24 Therefore, piezoelectric composite materials marrying both the advantages of piezoelectric polymers and piezoelectric ceramics are highly desired for a more satisfactory performance in 3D printing technology.…”
