“…However, increasing the concentration of Cu(II), it was possible to obtain a low formation of CuNPs in accordance with previous reports on the literature 36,37 . Other kind of methods to obtain CuNPs are liquid–liquid extraction, 38 co‐precipitation, 39 NPs 40–42 or solid‐phase extraction with relatively simple to perform 42 …”

This paper presents two modified copolymeric hydrogel films with thermo‐responsiveness. The final films are hydrogels containing N‐isopropylacrylamide, N‐N‐dimethylacrylamide, methyl methacrylate, and ethoxyethyl methacrylate. The incorporation of Ag and Cu in the smart hydrogel films endowed them with specific properties that could be useful in developing biological sensors, smart membranes, or flexible electronic components, which are proper for design and improvement on technology and biomedical applications. The films were synthesized in solution by gamma radiation at a dose rate of 10 kGy h−1, and an absorbed dose of 50 kGy. The characterization was realized by different spectroscopic and microscopic techniques as FTIR‐ATR, atomic force microscopy, SEM–EDX, TGA, and DSC. The hydrogel films were grafted with glycidyl methacrylate showing high resistance, biocompatibility, adequate adaptability, flexibility, in addition to the capacity of metal doping with silver and copper.

“…In this work, copper NPs stabilized by surfactant anionic type sodium dodecyl sulfate (SDS) were investigated. The particles were obtained by using the chemical reduction method in micellar solutions of surfactants according to the previously developed procedure [18] at a pH of 11.0 and the molar ratio of the precursor (copper chloride Before depositing the solution of copper NPs on glass substrates with ITO (Indium Tin Oxide) layer in the form of electrodes sample preparation of the suspension obtained by centrifugation on an Elmi CM 70M centrifuge (Latvia) and decanting the solution to remove excess surfactant was carried out. For this purpose in an eppendorf volume of 2.0 ml, 1.5 ml of a suspension of copper NPs and 0.5 ml of distilled water were placed.…”

This work is devoted to the study of the influence of the additional processing at 100, 200 and 300 • C on the morphology, microrelief, elemental composition of the surface and the electrophysical properties of glass/ITO/copper nanoparticle film structures. Studies have shown that with an increase in the processing temperature of the investigating samples reduces the amount of organic matter protecting the copper particles from oxidation. The conductivity of copper nanoparticles increases. The morphology of the surface and the elemental composition of the samples were studied by scanning electron microscopy. The microrelief of the surface and the measurement of the copper nanoparticles current-voltage characteristics were carried out using a scanning probe microscope in atomic force and scanning tunneling microscopy modes.

“…Sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB) are among the most widely-applied surfactants. SDS is an anionic, 32 while CTAB is a cationic surfactant, both with broad applicability spectra, which have already been used simultaneously. 33 Differently shaped AgBr microcrystals have already been synthesized using different surfactants/shape-tailoring agents, such as PVP 34,35 and CTAB (which can act as a shape-tailoring agent and can be used as bromide source as well 28,36 ).…”
