Acquisition of Atmospheric Pressure Plasma Jet System: A Practical Approach To Develop Functional Coatings
Abstract
We propose to acquire an Atmospheric Pressure Plasma Jet System with a linear plasma jet head suited to the deposition of films, capable of running with either Ar or He as carrier gas, able to incorporate a secondary and tertiary carrier gas, and able to deposit with two precursors simultaneously. This will provide a rare capability in the U.S. for research with Atmospheric Pressure Plasma Enhanced Chemical Vapor Deposition (APPECVD) in an environment rich in resources for the study of corrosion (through the DoD-initiated National Center for Education and Research on Corrosion and Materials Performance) and polymers (through the College of Polymer Science and Polymer Engineering). Graduate students will learn plasma polymerized film deposition and surface treatment techniques that have increased in importance rapidly over the last 20 years. The key research project is a collaboration with the Army Research Laboratory funded through the Technical Corrosion Collaboration (FA7000-14-2-20016). We are studying PECVD polymer films for replacing chromate pretreatment and primer layers in current corrosion protection systems to reduce VOCs and avoid chromate hazards. The objective is to compare the chemical quality and structure of AP-PECVD films with films deposited by conventional low pressure PECVD and linking that chemical quality and structure to the efficacy of corrosion protection in coating systems incorporating APPECVD films. Atmospheric plasma processes are needed to develop practical corrosion solutions with rapid deposition on widely varied structures and continuous processing. In a second project, surface wettability is tailored with PECVD coatings to make steamphobic and icephobic surfaces. A third project uses PECVD to modify robust polymeric membranes to create new means for oil/water separations. The final project studies how the wetting and adhesion of a thin polymer film surface can be tailored by altering its surface dynamics through interactions with a PECVD coating underneath the film. Acceptable for public release.
