Abstract
Poly(vinylidene fluoride) (PVDF) and poly(methyl methacrylate) (PMMA) were blended over the whole range of composition. DMA and SEM results indicated PVDF and PMMA were miscible. Mechanical properties showed when PMMA content was lower than 40%, the yield strength decreased and the elongation at break increased with the PMMA content. The PVDF/PMMA blend showed the lowest yield strength and the highest elongation at break which were 24 MPa and 762% respectively when PMMA content was 40%. The crystallization of PVDF decreased transmittance of the blends due to light scattering between the interface of crystal and amorphous phase when PMMA was as matrix.
