Multifaceted enhancement of piezoelectricity and optical fluorescence in electrospun PVDF-ceria nanocomposite.

ABSTRACT: This study investigates the enhancement of piezoelectric and optical fluorescence properties in electrospun polyvinylidene fluoride (PVDF) nanocomposite membranes doped with cerium oxide (Ce³⁺) at varying weight percentages. An optical characterisation using absorbance analysis found a blue shift in the bandgap of the ceria NPs, which also enhanced UV absorption in the PVDF polymer. At some additive doses, luminosity analysis demonstrated an incremental fluorescence impact. However, above a certain point, additional increases seemed to have a quenching effect, which decreased fluorescence. FTIR based analysis revealed the enhanced β sheets content to 61.75% in the sample of PVDF with a ceria 5 wt%. The fabricated nanofiber membrane displayed an average fiber diameter of around 1
