Abstract

Background: This work reports the effect of annealing temperatures on the crystalline structure of poly(vinylidene fluoride) (PVDF) film. The solution of PVDF/DMF deposited onto a glass substrate by spin-coatedto form a film of 10μm in thickness. The film is annealed at different temperatures at 30 minutes. The crystalline structure of the films investigates using XRD and FTIR techniques while the morphology determine using SEM. It observes that the dissolution of PVDF in DMF followed by spin-coating onto a glass substrate changed, directly, from alpha to beta phase which confirm by XRD and FTIR. The analyses of SEM show the surface is rough, porous and spherulites structure. They're moderately increasing of β-phase content that is equal 47% as PVDF powder to 76% as PVDF thin film. However, subsequent annealing process enhance the formation of β-phase suggesting the importance of this step.
