Abstract:
We have studied the influence of electric fields on highly viscous polymer films . An electrohydrodynamic(EHD) instability causes a wave pattern with a characteristic wavelength ë,leading to an array of polymer columns which span the gap of a capacitor device. When represented as a master curve, the data is quantitatively described by an EHD model, without any adjustable parameters. Our results suggest that EHD experiments using polymer films are
well suited to study non–equilibrium pattern formation in quasi two dimensional systems.
