Abstract
In a first aspect, a consolidated polymer film includes a first polymer layer having a first elastic modulus, wherein the first polymer layer comprises a non-melt-processible polymer comprising a polyimide, a poly(amide-imide), a block copolymer of a polyimide or a poly(amide-imide) or a mixture thereof, and a second polymer layer having a second elastic modulus, wherein the second polymer layer comprises a polyimide, a poly(amide-imide), a block copolymer of a polyimide or a poly(amide-imide) or a mixture thereof. A minor surface of the first polymer layer is in contact with a minor surface of the second polymer layer. The first elastic modulus is different from the second elastic modulus. The first and second polymer layers are bonded by consolidation.
