Preparation and characterization of dopamine-decorated hydrophilic carbon black

Design dopamine-modified polypropylene fibers towards removal of heavy metal ions from water

“…The peak situated at 1527 cm -1 corresponds to N-H shearing vibrations within polydopamine. 22 Moreover, the new absorption peak of dopaminemodified polypropylene at 3412 cm -1 , assigned to O-H shearing vibration of PDA, provides further evidence for the successful coating, consistent with the FTIR analyses of PDA homopolymer and dopamine monomer. Therefore, FTIR results confirm successful linkage of polydopamine onto the surface of the polypropylene fibers.…”

Flexible fiber-reinforced composites with improved interfacial adhesion by mussel-inspired polydopamine and poly(methyl methacrylate) coating

“…Briefly, substrates are simply soaked in a DA aqueous solution at room temperature, and a polydopamine (PDA) layer on the substrate surface is readily formed via the oxidative polymerization of DA [18]. Various substrates including hydroxyapatite, carbon nanotube, glass, polytetraethylene (PTFE), polyester, silicon rubber, etc., have all been surface-coated with PDA in a similar manner [19][20][21][22][23][24][25][26][27]. The method would not ruin any structure of the original substrate, and it is extremely useful for biomedical applications because it does not require the time-consuming synthesis of complex linkers and the process is solvent-free and nontoxic.…”

Facile immobilization of polyaspartate onto silica gels via poly(dopamine) for the removal of methylene blue from aqueous solution

“…The intense bands at 1086 and 798 cm −1 were related to the unsymmetrical stretching vibration and symmetrical stretching vibrations of Si O Si, respectively. For SG-pD, in addition to the weaken peak at 3437 cm −1 , a new weak peak at 1512 cm −1 appeared, which should be in correspondence to the N H stretching vibration [35], resulted from the structures of indole or indolone in polydopamine [36,37]. After treatment of SGpD with pA, a new sharp peak at 1581 cm −1 was observed, which was attributed to the stretching vibration of amide II band from pA. Additionally, the strong peak at 1399 cm −1 ascribed to COO −1 in pA shifted to a shoulder peak at 1452 cm −1 , which was assigned to the carboxylic group COOH.…”
