Abstract: A multilayer film can comprise: a plurality of layers, preferably 4 layers to 128 layers, comprising: a polymer A layer comprising a polycarbonate copolymer and a polymer B layer comprising a semi-crystalline polyester; wherein a differential solubility parameter (ΔδAB) of polymer A towards polymer B (ΔδAB) is greater than or equal to 2.6 MPa1/2; and an interdiffusion region between each polymer A and polymer B. The multilayer film has a dynamic flexure of greater than or equal to 200,000 cycles, as determine by bending 180° on a 10 mm radius cylinder at a rate of 1 hertz. The multilayer film has a total thickness of 40 μm to 70 μm, a transmission at 360 nm to 750 nm of greater than or equal to 89% and a haze of less than or equal to 1%.

Abstract: A foldable cover assembly includes a glass layer having a first surface, a second surface opposite the first surface, a first thickness at a first location and a second thickness at a second location, wherein the second thickness is less than the first thickness. The second thickness is further effective to provide bendability to the glass layer. The foldable cover assembly further includes an optically clear polymer film disposed on the first surface of the glass layer. The polymer film includes a thermoplastic polymer, a thermoset polymer, or a combination comprising at least one of the foregoing, wherein a 100 micrometer-thick sample of the optically clear polymer film transmits greater than 85% of visible light as determined according to ASTM D1003-00. A method for the manufacture of the foldable cover assembly is also described. The foldable cover assembly can be useful for use with an electronic device.
