Water-soluble stable polymer nanocomposites with AuNPs based on the functional poly(1-vinyl-1,2,4-triazole-co-N-vinylpyrrolidone)

New water-soluble polymer nanocomposites with gold nanoparticles (AuNPs) were synthesized using functional copolymer of 1-vinyl-1,2,4-triazole with N-vinylpyrrolidone (poly(VT-co-VP)) as a stabilizing matrix. The polymer AuNPs nanocomposites were studied by transmission electron microscopy, scanning electron microscopy, ultraviolet–visible spectroscopy, Fourier transform infrared spectroscopy, X-ray diffraction, atomic absorption and thermogravimetric analysis. The gold content in nanocomposites ranged from 4.4 to 25.7%wt (the gold content depends on the ratio of poly(VT-co-VP):Au (III)). The obtained polymer nanocomposites consist of isolated gold nanoparticles with a diameter of 1–12 nm having a predominately spherical shape, which are uniformly distributed throughout the bulk of the polymer matrix. Nanocomposites contain AuNPs of various sizes, which is determined by the ability of the polymer matrix to stabilize the different metal contents. The resulting AuNPs nanocomposites are promising materials for the design of novel hydrophilic antiseptics and antimicrobial components for medical purposes.

Synthesis of 1,2,4-triazolium salt-based polymers and block copolymers by RAFT polymerization: Ion conductivity and assembled structures

Well-defined 1,2,4-triazolium-based polymers were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of N-vinyl-1,2,4-triazolium salts, i.e., N-vinyl-4-ethyl-1,2,4-triazolium bromide (NVETri-Br) and N-vinyl-(4-ethoxyethyl)-1,2,4-triazolium bromide (NVEtOETri-Br). Reasonable control of the polymerization of these monomers was attained using a trithiocarbonate-type chain transfer agent (CTA), producing poly(N-vinyl-1,2,4-triazolium bromide)s with controlled molecular weights (Mn,SEC > 20000) and low values (Mw/Mn 2) proceeded selectively to afford amphiphilic block copolymers composed of hydrophobic poly(NVETri-NTf2) and hydrophilic nonionic segment, poly(NVP) or poly(NVTri). The ionic conductivity of poly(NVP)33-b-poly(NVETri-NTf2)67 was 4.3 × 10-5 S/cm at 25 °C, which was remarkably higher than that of poly(NVETri-NTf2) (1.7 × 10-5 S/cm). At 90 °C, poly(NVP)-b-poly(NVETri-NTf2) exhibited high ionic conductivities of 3.1-2.3 × 10-4 S/cm under the ambient humidity conditions, depending on the comonomer composition (NVP content = 12-33%). We believe that this represents the first report on controlled synthesis of 1,2,4-triazolium-based polymers and block copolymers that exhibit high characteristic ion-conducting properties, depending on the structure of the substituent group, counter anion, comonomer structure, and composition.
