Polydopamine film coating on polyurethane foams as efficient “sunscreen”. Application to photocatalysis under UV irradiation

Pd-functionalized polydopamine-coated polyurethane foam: a readily prepared and highly reusable structured catalyst for selective alkyne semi-hydrogenation and Suzuki coupling under air

“…Inspired by the mussel-like adhesive principle, 7 some of us recently reported the successful coating of PUFs with an adhesive layer of polydopamine (PDA) by simple immersion in a buffered aqueous solution of dopamine, their further functionalization with both inorganic and molecular catalysts, and application in catalysis or dye degradation. [8][9][10][11][12][13][14] The PDA strongly adhesive properties ensured the robust anchoring of the catalysts, leading to high activity and stability over a high number of cycling tests, as well as to the absence of catalyst leaching in the liquid medium. The high versatility of PDA, which can interact with virtually any kind of surfaces and can be easily functionalized is the critical point.…”

Stable and Flexible Polyurethane Membranes with WO3/Bi2MoO6 Nanoparticles for the Photocatalytic Degradation of 2,4-Dichlorophenol

“…Such breakage may exacerbate the hydrolysis process of the ester bonds, leading to the generation of acidic products. The aqueous environment’s high concentration of h + promotes polyester hydrolysis, increasing water absorption . The addition of a photocatalyst gradually increased the contact angle of the composite film, creating a hydrophobic surface that facilitates further adsorption of pollutant molecules.…”

A Study on the Preparation and Cavitation Erosion Mechanism of Polyether Polyurethane Coating

“…In order to improve the CE resistance of parts, coating their surface with good CEresistant materials is one of the most common and economical methods [9][10][11]. Due to its excellent impact resistance, wear resistance, energy absorption capacity and biocompatibility, polyurethane (PU) coatings have attracted increasing attention in recent years [12][13][14]. Chi et al studied the CE performance of epoxy resin coating, commercial epoxy resin coating, PU coating, glass-flake-reinforced epoxy resin coating and silicone resin coating [15] and found that the PU coating, with greater toughness and ductility, had better CE resistance than other coating materials.…”
