Abstract :
Poly(vinylidene fluoride) (PVDF) and poly(methylmethacrylate) (PMMA) have been doped with crystal violet and disperse red. Field-induced alignment of the azo dye disperse red dissolved in PMMA results in piezo- and pyroelectric activity. piezo- Field poling of PVDF films doped with crystal violet produces and pyroelectric polymer films with high absorbance in the visible spectral range. Piezo- and pyroelectric properties of the doped films are presented
