Abstract
Official abstract text for this publication.
A method of synthesizing multilayer heterostructures including an inorganic oxide layer residing on a solid substrate is described. Exemplary embodiments include producing an inorganic oxide layer on a solid substrate by a liquid coating process under relatively mild conditions. The relatively mild conditions include temperatures below 225° C. and pressures above 9.4 mb. In an exemplary embodiment, a solution of diethyl aluminum ethoxide in anhydrous diglyme is applied to a flexible solid substrate by slot-die coating at ambient atmospheric pressure, and the diglyme removed by evaporation. An AlO x layer is formed by subjecting material remaining on the solid substrate to a relatively mild oven temperature of approximately 150° C. The resulting AlO x layer exhibits relatively high light transmittance and relatively low vapor transmission rates for water. An exemplary embodiment of a flexible solid substrate is polyethylene napthalate (PEN). The PEN is not substantially adversely affected by exposure to 150° C.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: providing an organometallic solution, the organometallic solution including an organometallic compound dissolved in a complexing solvent; distributing the organometallic solution on a solid substrate, wherein the solid substrate comprises an organic polymer and the distributing is by a first liquid coating process; removing the complexing solvent; and curing the organometallic compound to form a metallic oxide from the organometallic compoun…
