Abstract Scope |
Open-air spray-plasma processing provides opportunities for scalable and low-cost coating deposition on large and/or complex shapes in air and at low temperature. The generally solvent-free process further allows for the simultaneous functionalization of surfaces and subsequent coating deposition in a single step.
I describe understanding of the plasma properties and plasma-initiated materials deposition and curing mechanisms for processing of coatings. Open-air spray and plasma process does not require costly vacuum or low-pressure inert gas environments, enabling order of magnitude improvements in manufacturing scalability and throughput. The plasma-initiated interactions with materials at the atomic level using plasma-enhanced chemistry holds significant promise for surface functionalization and coating deposition.
We describe what is understood regarding the equilibrium and non-equilibrium open-air plasma-initiated film growth mechanisms to create coating compositions and structures. I will discuss deposition of several functional coatings and metrologies to characterize the moisture barrier, adhesive and degradation processes important for reliable application. |
