Corona charging of polymers: recent advances on constant current charging
TL;DR: A brief overview on the recent developments of corona charging of polymers, with emphasis on the current corona triode, can be found in this article, where a few examples of the use of the constant current triode in the investigation of electrical properties of nonpolar and ferroeleectric polymers is discussed.
Journal ArticleDOI
Point-to-plane corona: current-voltage characteristics for positive and negative polarity with evidence of an electronic component
TL;DR: In this article, a series of measurements carried out with the point-to-plane symmetry has shown that positive corona confirms the Townsend relation while for the negative corona this happens only at large point to plane distances.
Journal ArticleDOI
Electric field distribution and near-surface modifications in soda-lime glass submitted to a dc potential
TL;DR: In this paper, the authors employed the laser-induced pressure pulse method (LIPP) to investigate the electric field distribution in soda-lime glass samples after application of a dc potential (dc poling).
Journal ArticleDOI
Phase transition in poly(vinylidene fluoride) investigated with micro-raman spectroscopy
Carlos J. L. Constantino,Aldo Eloizo Job,Rebeca Delatore Simões,José A. Giacometti,Valtencir Zucolotto,Osvaldo N. Oliveira,Giovani Gozzi,D. L. Chinaglia +7 more
TL;DR: Poling with negative corona discharge was found to affect the α-PVDF morphology, improving the Raman bands related to this crystalline phase, and corona-induced effects could not be observed with the other experimental techniques.
Journal ArticleDOI
Optically Induced Birefringence and Surface Relief Gratings in Composite Langmuir−Blodgett (LB) Films of Poly[4‘-[[2-(methacryloyloxy)ethyl]ethylamino]-2-chloro-4-nitroazobenzene] (HPDR13) and Cadmium Stearate

TL;DR: In this article, photoinduced optical storage and surface relief gratings were demonstrated in mixed Langmuir−Blodgett (LB) films of poly[4]-[[2-(methacryloyloxy)ethyl]ethylamino]-2-chloro-4-nitroazobenzene] (HPDR13) and cadmium stearate (CdSt).
