Microtribological and electrochemical corrosion behaviors of polydopamine coating on APTS-SAM modified Si substrate

Effect of polydopamine deposition conditions on fouling resistance, physical properties, and permeation properties of reverse osmosis membranes in oil/water separation

“…Several previous studies demonstrated that the polydopamine film thickness increases at higher dopamine concentration in the deposition solution [29,34,35] or with longer deposition time [25,28,29,[33][34][35]. Also, the polydopamine coating growth rate [34] and dopamine reaction rate [48] increase with dopamine concentration. Our results corroborate McCloskey et al's findings in that the pure water flux of polydopaminemodified XLE RO membranes decreased relative to that of unmodified XLE RO membranes as deposition time increased [25].…”

“…Prior publications report changes in surface characteristics (e.g., contact angle, coating thickness, roughness, etc.) of polymers modified with polydopamine applied at various dopamine concentrations, polydopamine deposition times, and dopamine solution pH values [25,[29][30][31][32][33][34][35]. Recently, Azari and Zou have reported that deposition of a compound structurally related to dopamine, L-dopa, onto reverse osmosis desalination membranes reduced the static adhesion of bovine serum albumin (BSA) to the membrane surface and improved the fouling resistance of these desalination membranes when filtering water containing foulants such as BSA, alginic acid sodium salt, or dodecyltrimethyl ammonium bromide (DTAB) surfactant [36].…”

Deposition Mechanism and Properties of Thin Polydopamine Films for High Added Value Applications in Surface Science at the Nanoscale

“…A great part of the corrosion inhibition in the presence of 3.5% NaCl (w/v) solutions may hence be due to a lack of direct contact between water and copper [69]. In a similar manner, silicon [84] and aluminum [85] were modified with (3-mercaptopropyl)trimethoxysilane before deposition of the polydopamine film and further modification with tetradecanoyl chloride. Significant improvement in the inhibition of corrosion was found on the surface of these materials.…”

Substrate-independent sequential deposition process to obtain the lotus effect based on mussel-inspired polydopamine

“…The thickness and morphology of the so-deposited PDA has been characterized elsewhere [5,6]. Herein, we aim to evaluate the adhesion between PDA and substrates by an ultrasonication treatment.…”
