Biomimetically modified chitosan for electrophoretic deposition of composites

Dispersant Molecules with Functional Catechol Groups for Supercapacitor Fabrication

“…Significant interest has been generated in the synthesis of polymer adhesives, containing catecholate monomers [ 16 , 17 , 18 ] and modification of polymers with catechol molecules [ 19 , 20 ]. The adsorption of catecholates on semiconductors allowed for enhanced charge transfer, advanced optical and photovoltaic properties, which were used for the development of various photovoltaic devices and sensors [ 21 , 22 , 23 ].…”

“…Many applications of catecholates are based on their interesting redox properties [ 32 , 33 , 34 ]. Catecholate molecules were used as reducing agents for the synthesis of inorganic nanoparticles by chemical precipitation methods [ 20 , 32 ]. Moreover, there is a growing interest in the applications of redox active catecholates for the fabrication of electrochemical sensors [ 19 , 20 ] and supercapacitors [ 35 ].…”

Biomineralization of 2304 duplex stainless steel with surface modification by electrophoretic deposition

“…Iodine (99.9% purity, AnalaR, England) was also used as a dispersant and to enhance the surface charge (this resulted in positively charged particles). 36 The 2304 DSS plate (OutoKumpu, Sweden) was utilized as a material of substrate and was used as the counter electrode in the EPD cell.…”

Micelle-embedded coating with ebselen for nitric oxide generation

“…Catechol-conjugated chitosan (CS-C) was synthesized using chitosan ( M w 100 kDa, 80% deacetylated; Sigma-Aldrich) and 3,4-dihydroxybenzaldehyde (3,4-DHB; Sigma-Aldrich) following previously published method by Clifford et al 26 The catechol was conjugated to the amine groups of chitosan by Schiff base reaction. Methanol was used to dissolve 3,4-DHB, NaBH4 (Sigma-Aldrich) as a reductant was used to reduce the C=N to C-N, and the degree of catechol substitution on the backbone of chitosan was determined by proton nuclear magnetic resonance.…”
