Molecular level investigations on mussel inspired polymer thin films using nonlinear vibrational spectroscopy

The development of surface coatings demands a better understanding surface/interface chemistry to design high-performance coating materials. We have studied the polymerization processes mussel-inspired adhesive protein, Dopamine. Molecular level insight on mechanism thin film formation during has been probed using sum frequency generation vibrational spectroscopy. investigations polydopamine films with variation in time dopamine at air-polymer interface reveal molecular footprints and dopamine. intermediates were dependent time, which can be used for immobilization strategies. Additionally, morphological measurements show nanoparticles surfaces even when vertical orientation sample and/ or stirring solution followed prevent macro/nanostructures. acquired applied designing deterministic interfaces coating, coupling, sensing applications.
