Abstract
A multilayer plastic substrate. The substrate comprises a plurality of thin film layers of at least one polymer, the plurality of thin film layers being adjacent to one another and having sufficient strength to be self-supporting, wherein the multilayer plastic substrate has an average visible light transmittance of greater than about 80%.
Claims23
A multilayer plastic substrate consisting essentially of:
- a plurality of flash evaporated thin film layers of at least one polymer, the plurality of thin film layers being adjacent to one another and having sufficient strength to be self-supporting, wherein the multilayer plastic substrate has an average visible light transmittance of greater than about 80%, wherein the multilayer plastic substrate comprises at least about 50 thin film layers, and wherein the multilayer plastic substrate has a surface roughness of less than about 10 nm.
