Electric-Field-Assisted Photopolymerisation: Filler Orientation, Charge Migration, Dielectrophoresis and Network Formation

Electric fields can orient suspended inclusions, drive dielectrophoretic migration and alter charge distributions while a photopolymer network is forming. ER-356 examines how those electrical forces compete with viscous drag, Brownian motion and the rapidly increasing resistance to motion during cure. Field strength and gradient, particle polarizability, conductivity and gelation time are treated as coupled state variables rather than independent settings. In-situ electrical measurements, optical or tomographic orientation measurements and post-cure anisotropy tests are combined with polarity, frequency and gradient perturbations. The resulting qualification logic distinguishes useful field-assisted alignment from electrode reactions, non-uniform migration and cure-arrest effects.
