Abstract
Disclosed is a method relating to graded-composition barrier coatings comprising first and second materials in first and second zones. The compositions of one or both zones vary substantially continuously across a thickness of the zone in order to achieve improved properties such as barrier, flexibility, adhesion, optics, thickness, and tact time. The graded-composition barrier coatings find utility in preventing exposure of devices such as organic electro-luminescent devices (OLEDs) to reactive species found in the environment.
