dc.description.abstractInterest in poly (vinylidene fluoride) (PVDF) beta-phase is high due to the piezoelectric properties that this polymer presents in this phase. From a manufacturing standpoint, the understanding how processing parameters alter crystallization behavior may inform future methods to produce piezoelectric binders during a 3D printing process. For this reason, secondary nucleation kinetics of PVDF and poly (methyl methacrylate) (PMMA) were studied under various shear and cooling rates to better inform processing parameters in future printer design. PMMA was added because of the good miscibility that presents with PVDF, as well as the increase in melt flow rate (MFR) and adhesion, both also key features in 3D printing. While different cooling rates were not significant to the effect of the crystal size, neither were holding the samples at different times in the crystallization temperature, resulting in all similar to the crystallization growth rate. Furthermore, the variation of shear rates was studied with also the addition of PMMA. This analysis revealed that the effect of shear rate results in a higher crystallinity ratio. The addition of PMMA makes the crystal density increase. These findings indicate that by changing PMMA concentrations, shear ratios and thermal properties can be altered to suit specific needs of crystallinity ratios, beta-phase content and crystal average size.
