Fabrication and Optical Characterization of Polyvinylidene Fluoride/Neodymium Oxide Nanocomposite Films

Abstract

Polyvinylidene fluoride (PVDF) is employed in a wide range of devices based on its excellent mechanical, optical, high thermal, piezoelectric, pyroelectric, and ferroelectric characteristics. In the current investigation, the pristine and neodymium oxide (Nd 2 O 3 ) nanoparticles embedded polyvinylidene fluoride (PVDF) thick films were prepared via solution casting method. The Nd 2 O 3 nanoparticles were synthesized via hydrothermal technique. The functional groups were identified in the nanocomposite films via infrared vibrational spectroscopy. It revealed the presence of ferroelectric β-phase in the annealed nanocomposite films. All-important optical constants have been determined for the first time via UV-VIS transmission spectroscopy for the nanocomposite films in the ferroelectric phase.

“…Rare-earth (RE)-doped wide band-gap semiconductors exhibit sharp and intense emission covering a wide (visible to near-IR) spectral range [1] [2] [3] [4] [5].…”

Linear Optical Constants of Polyvinylidene Fluoride/Praseodymium Oxide Nanocomposite Films in the Ferroelectric Phase

“…There are many EAPs, namely, Nylon-11, polylactide and aniline pentamer copolymer, poly (lactic-co-glycolic acid) (PLGA), and poly (vinylidene fluoride) (PVDF) and its copolymers with trifluoroethylene (TrFE) [3][4][5][6]. However, PVDF and PDVF-TrFE exhibit the best electro active properties, such as piezo-, pyro-and ferroelectricity, and optoelectronic [7,8]. As a result, PVDF and its copolymers are of choice for the increasing number of possible organic microelectronics applications, such as electro-optic transducers, waveguides, sensors, actuators, energy harvesting, electro-optic memory,…”
