Abstract:
Transfer films, articles made therewith, and methods of making and using transfer films to form an electrical stack are disclosed. The transfer films may include a plurality of co-extensive electrical protolayers forming an electrical protolayer stack, at least selected or each electrical protolayer independently comprising at least 25 wt % sacrificial material and a thermally stable material and having a uniform thickness of less than 25 micrometers. The transfer films may include a plurality of co-extensive electrical protolayers forming an electrical protolayer stack, at least selected or each protolayer independently exhibiting a complex viscosity of between 103 and 104 Poise at a shear rate of 100/s when heated to a temperature between its Tg and Tdec.
