Abstract:
In one embodiment, a multilayer article can comprise: a multilayer substrate M, comprising: greater than or equal to 16 polymer A layers, preferably 16 to 512 polymer A layers; and greater than or equal to 16 polymer B layers, preferably 16 to 512 polymer B layers; wherein the polymer A layers and the polymer B layers are present in a ratio of 1:4 to 4:1, preferably the ratio is 1:1; a protective layer P; and an identification layer I between the protective layer P and the multilayer substrate M; wherein the identification layer I comprises information, and wherein the protective layer P prevents alteration thereof.
Abstract:
A method for preparing a high temperature melt integrity separator, the method comprising spinning a polymer by one or more of a mechanical spinning process and an electro-spinning process to produce fine fibers.
