Study of water uptake and failure modes in protective polymer coatings
Polymer based barrier coatings are important, as they are effective at inhibiting corrosion. In this proposal we plan to study the water transport and distribution in thin planar epoxy inorganic interface layers analogous to the polymer particle interfaces present in actual epoxy network composites.. We want to depth profile the water volume fraction in these polymer layers using neutron reflectivity kinetically using D2O uptake and then subsequent exchange with H2O. To ascertain the solvent exchange kinetics along with any difference in water distribution in these films. We will be able to quantify water enrichment/depletion at the polymer layer/substrate interface. This study will enable us to understand the importance of the many polymer/inorganic interfaces which are present in fully formulated coatings, which have additives of micro and nanoparticles, and so lots of interface. Also knowing the polymer solvated volume fractions and dynamics will allow us to produce accurate simulations which will help us to generate important predictions and insight.
