| This work presents the creation of a novel hybrid polyurethane/POSS polymer by incorporating various loading percentages of a cylcopentyl T8 POSS cage onto the backbone of a DEFT class H, type 1 polyurethane coating. The POSS cage of Cy7T8(OSiMe2H) was attached to a reactive diol of trimethylolpropane allyl ether via a silation reaction. This compound was then incorporated into a polyurethane backbone with varying percentages of T8 cages by reacting the POSS diol with polytetramethyleneglycol and hexamethylene diisocyanate to create a step-growth polymer backbone. Coatings of the hybrid polymer were sprayed onto AA2024 aluminum alloys substrates and evaluated using electrochemical impedance spectroscopy and contact angle measurements. |
