ABSTRACT:
A method of preparing a film includes the steps of mixing a thermotropic liquid crystalline polymer with a host polymer to provide a first material, coextruding the first material with a second material so as to form a film comprising the first and second materials, quenching the film, and orienting the quenched film in at least one direction. The oriented film has an exposed first major surface that includes protrusions resulting from regions of the liquid crystalline polymer in the host polymer.
