Silver(I) complex with a Schiff base ligand extended waterborne polyurethane: A developed strategy to obtain a highly stable antibacterial dispersion impregnated with in situ formed silver nanoparticles

Waterborne polyurethane nanocomposite incorporated with phytic acid intercalated layered double hydroxides: A highly stable aqueous dispersion with desired corrosion protection capability

“…The zeta potentials of WPU, WPU/LDH, and WPU/PA-LDH samples were obtained À74.5, À78.6, and À82.3 mV, respectively (Figure 7(C)), which confirm their high stability for a long time. 35 The effect of the incorporated nanosheets on the morphology and microstructure of WPU, WPU/LDH, and WPU/PA-LDH films were inspected by XRD measurement (Figure 9(A)). Commonly, in polyurethanes, the microphase separation degree of soft segment and hard segment domains significantly affects crystallinity.…”

Mechanically robust, creep-resistant, intrinsic antibacterial and reprocessable dynamic polyurethane networks based on azine moieties

“…37 Azines are a special representative of Schiff bases, 38 which can exchange at elevated temperatures 30,39 and possess antibacterial properties. 40,41 Ma's group have synthesized an epoxy monomer containing azine moiety and prepared dihydrazone CANs with excellent mechanical properties, creep resistance, controlled degradability, and inherent antibacterial properties. 42 However, the azine groups have not been applied in dynamic crosslinked polyurethane networks to the best of our knowledge.…”

Effect of Cellulose Nanofibrils on the Properties of Jatropha Oil-Based Waterborne Polyurethane Nanocomposite Film

“…There are a number of nanofillers that can be used to produce nanocomposites. These nanofillers are carbon nanotube [ 7 , 8 , 9 ], nano-silica [ 10 , 11 ], graphite and its derivatives [ 12 , 13 , 14 ], nanosilver [ 15 , 16 , 17 ], and nanoclay [ 18 ]. However, these nanofillers are not preferred due to their tendency to sediment easily during the mixing and curing process of the nanocomposite.…”
