The low electrical conductivity of silk textile structures is a crucial factor limiting their practical applications. Silk-based materials need modifications with different electroconductive compounds and structures. This report presents functionalization with silver nanowires (AgNWs) using polydopamine (PDA) as a linker. AgNWs create 3 and 10 g/m 2 conductive networks on silk fabric. The surface resistance is estimated to be 1.5 Â 10 5 Ω and 1.0 Â 10 3 Ω, while volume resistance is 2.3 Â 10 3 Ω and 6.8 Â 10 2 Ω respectively to less and more developed AgNWs networks. AgNWs-coated silk fabric is more thermally stable and provides thermal shielding. AgNWs functionalization makes silk fabric more hydrophilic due to PDA and polyvinylpyrrolidone (PVP) influence.PVP acts as a capping agent during AgNWs synthesis and remains on their surface. Silk fabric functionalized with AgNWs reveals above 99.94% reduction of bacterial growth against Gram-positive and -negative bacteria Staphylococcus aureus and Klebsiella pneumoniae, respectively. The bacteriostatic and biocidal coefficients are respectively above 7.2 and 3.3 for both bacteria types. AgNWs do not harmfully influence excellent silk mechanical properties. The specific strength does not change significantly and the elongation at break is even improved. The presented AgNWs functionalized silk fabric has useful physical, antimicrobial, and electronic properties for designing multimodal textile products.

“…Notably, several new peaks at 725 to 500 cm −1 for C-PDA-1.0% PVP-6h confirmed the existence of hydrogen bonds between the γ-lactam and catechol group on PDA. 33 Figure 5c 34,35 However, the surface C−N/C−O ratio of C-PDA-1.0% PVP-6h was notably higher than that of C-PDA-6h, increasing from 18.91 to 24.07%, which confirms the presence of PVP-containing γ-lactam in the structural colored film of the cotton fabric. The O−CO ratio drops of C-PDA-1.0% PVP-6h, which may be attributed to the cotton fabric surface, is more tightly covered by the PDA film.…”

“…The strong peak at 1290 cm –1 can be assigned to the C–N stretching vibration, while the characteristic peak near 1050 cm –1 can be assigned to the C–O–C stretching vibration of cotton fabrics. Notably, several new peaks at 725 to 500 cm –1 for C-PDA-1.0% PVP-6h confirmed the existence of hydrogen bonds between the γ-lactam and catechol group on PDA …”

Structural coloration is an important way to realize eco-friendly dyeing of textiles. Structural colored cotton fabric was obtained by fabricating a polydopamine (PDA) film on the white cotton fabric at different polymerization reaction times. PDA is prone to generate capillary tension during film formation, which damages the uniformity and interfacial bonding force of the film. Multiple hydrogen bonds will form between the lactam group of polyvinylpyrrolidone (PVP) and the phenolic hydroxyl group of PDA. The introduced hydrogen bonds will effectively enhance the interfacial bond strength and lead to structural color with high color fastness. The surface morphology of double-layer aggregates of the PDA film on structural colored cotton fabric was revealed by scanning electron microscopy. The chemical constitution of the PDA film and PVP was investigated by Fourier transform infrared spectroscopy and X-ray diffraction. The color characteristics of structural colored cotton fabrics were analyzed by UV–vis reflectance spectroscopy and spectrophotometry.

“…Poly( N -vinyl-2-pyrrolidone) is one of the water-soluble polymers promising for the creation of adhesive compositions [ 1 ], wastewater treatment systems [ 2 , 3 ] and drug delivery [ 4 , 5 , 6 ]. Poly( N -vinyl-2-pyrrolidone) is also used to impart hydrophilic properties to fibers [ 7 , 8 ], as a modifier and pore-forming agent in the preparation of membranes [ 8 , 9 , 10 , 11 ], as well as for the formation of nanoparticles [ 12 , 13 ] and hydrogels [ 14 ]. Although poly( N -vinyl-2-pyrrolidone)-based hydrogels are promising for the inclusion of drugs and water treatment [ 6 ], the chemical inertia of N -vinyl-2-pyrrolidone residues [ 5 , 6 ] creates impediments for crosslinking chains in one stage under mild conditions.…”

The aim of the study is to search for a reaction that provides the possibility of tandem “one-pot” formation of polymer networks during radical copolymerization of N-vinyl-2-pyrrolidone and glycidyl methacrylate. It was shown that the addition of recently synthesized 1,3-dimethylimidazolium (phosphonooxy-)oligosulfanide makes it possible to obtain a cross-linked copolymer in one stage as a result of radical copolymerization of N-vinyl-2-pyrrolidone and glycidyl methacrylate with a molar ratio of monomers less than 1.4. The structure of the copolymerization products of N-vinyl-2-pyrroldione and glycidyl methacrylate formed in the presence of 1,3-dimethylimidazolium (phosphonooxy-)oligosulfanide was characterized by 1H NMR, FTIR and MALDI spectroscopy. 1H NMR spectroscopy revealed an interaction under moderate heating between glycidyl methacrylate and 1,3-dimethylimidazolium (phosphonooxy-)oligosulfanide, accompanied by the formation of a mixture of unsaturated products of complex structure, presumably acting as crosslinking agents. It is shown that when the molar ratio of N-vinyl-2-pyrroldione/glycidyl methacrylate comonomers is 0.89, a densely crosslinked copolymer is formed, capable of limited swelling in water with a velocity constant of 5.06 × 10−2 min−1 and an equilibrium degree of swelling of about 227%.
