- Abstract
- Polyvinylidene fluoride (PVDF)/Polymethylmethacrylate (PMMA) blended films were optimized by changing the PMMA concentration in PVDF/PMMA blends for use as protective sheets for photo-voltage cells and modules. Films of poly(vinylidene fluoride) (PVDF) and poly(methyl methacrylate) (PMMA) blends were prepared by thermal extrude casting. The rheological properties, chemical structure, crystalline behavior, thermal, morphology, optical properties and contact angle of the PVDF/PMMA blend films were examined by RDS, FTIR, XRD, DSC, TGA, SEM and color spectrometry. The PVDF/PMMA blend containing 30 wt.% PMMA showed good performance for potential applications as the protective sheet in photo-voltage cells and modules. The α and β crystalline phases in the films decreased and increased, respectively, with increasing PMMA content. The shear viscosities increased with increasing PMMA content. The melt temperature (Tm) and crystalline temperature (Tc) of the blends decreased with increasing PMMA content.
