Effect of electrospinning conditions and addition of metal nanoparticles on morphology and β-phase formation in PVDF nanofibers

Polyvinylidene fluoride (PVDF) is one of the most studied polymer systems that exhibits piezoelectric, pyroelectric, and ferroelectric properties. It is well known that PVDF has at least four different crystalline forms that consists of α, β, γ and δ phases. It has been shown that nanofiber morphology and crystalline fraction influenced by processing conditions. This research focuses on study of effect of electrospinnin parameters such as applied voltage, solution feed rate and concentration on fiber morphology and β phase fraction furthermore results comparing to composite nanofiber that preparing by addition of metal nanoparticles
