Surface Preparation and Passivation by Catechol-Containing Polymers
Abstract
Marine Corps ground vehicles are covered with a Chemical Agent Resistant Coating (CARC) that eases the removal of chemical warfare a,gents. However, this CARC does not bond well to the underlying metal vehicle structures. Furthermore, extensive corrosion of the met,al substrates occurs. In efforts described here, we will be using a biomimetic material, modeled after the adhesive of marine mussel,s, to provide a rustproof coating while also enhancing the bonding of CARC to vehicles. Several new coating formulations will be dev,eloped, starting from the poly(catechol-styrene) biomimetic adhesive system. Rapid screening will be used to assess initial anticorr,osive properties. Further coating aspects will be examined and modified including hardness and durability. Coating samples will be p,rovided to Navy personnel at NSWC Carderock for additional testing as well as independent verification and validation of results. At, the end we aim to generate a new coating technology for enhancing Marine Corps vehicle readiness and longevity. Specific aims for t,his project are to:Aim #1: Develop biomimetic adhesive formulations that prevent rusting Aim #2: Generate coating formulations conta,ining plasticizers Aim #3: Incorporate corrosion inhibitors into coatings Aim #4: Form corrosion inhibitors during cure of coating s,Aim #5: Test CARC compatibility and salt spray resistance of coatings(Approved for public release.)
