Non-linear dynamics of a viscoelastic film subjected to a spatially periodic electric field

•We model the flow of polymer films under a heterogeneous electric field.•The role of normal and shear polymeric stresses changes in the non-linear regime.•Lubrication approximation is inappropriate at late times.•A metastable state arises with finite interfacial deformation for low Ca values.•Visco...
