摘要
(US20170282214) Methods and systems for deposition of blended polymer films are disclosed.  According to an aspect a method of producing a film on a substrate includes combining a guest material, a host matrix, and a solvent having one or more hydroxyl (O—H) bonds to form a target emulsion.  The method also includes exposing the target emulsion to an infrared source that is tuned to an absorption peak in the host matrix that is reduced in or absent from the guest material thereby desorbing the host matrix from the target emulsion and lifting the guest material from the surface of the target emulsion.  The target emulsion and the substrate are oriented with respect to each other such that the lifted guest material is deposited as a film upon the substrate.
