WebPublication Polymers (20734360) Volume 14, Issue 20, ... In this paper, we present a detailed hydrodynamic study of six commercial diblock copolymers featuring the same hydrophilic block (poly(ethylene glycol), PEG; degree of polymerization is ca. 110 ± 25) and the following hydrophobic blocks: polystyrene, PS35-b-PEG115; ... Web8 apr. 2024 · The intensity of the absorption from 3307 to 3315 cm −1 (stretching of the -NH in the urethane group) decreases as the molecular weight of PEG increases because the number of urethane segments decreases proportionally within the total molecular weight of the polymer. It was found that the increase in PEG weight leads to a decrease in the …

WebSequential interpenetrating polymer networks (SIPNs) composed of poly(2-hydroxyethyl methacrylate) (PHEMA) and polystyrene (PS) were synthesized by photopolymerization at room temperature. A common solvent, N,N-dimethylformamide, was used to impregnate the styrene monomer into the PHEMA network. WebHybrid organic-inorganic (dendritic polymer-silica) xerogels containing silver nanoparticles (Ag Nps) were developed as antibacterial leather coatings. The preparation method is environmentally friendly and is based on two biomimetic reactions. Silica gelation and spontaneous Ag Nps formation were both mediated by hyperbranched poly (ethylene …
