Special Issue Information

Dear Colleagues,

The last three decades have been marked by fundamental and technological breakthroughs in the production and use of nanomaterials. At the same time, the establishment of laws governing the synthesis of nanoparticles, the regulation of their structure and properties, as well as the search for new areas of their application remain priority areas for research into their development. The present Special Issue aims to create a collection of high-quality original articles and reviews on the synthesis, properties and applications of polymer-containing nanoparticles and polymer nanocomposites. Priority will be provided to manuscripts describing new methods for obtaining polymer-containing nanoparticles, nanocomposites and other nanomaterials for their use in the creation of structural materials and materials with special properties, including those for use in medicine and biology. Manuscripts dedicated to nanomaterials for molecular electronics, creating sensor systems, monitoring the composition of mixtures and determining the concentrations of individual substances, including metabolites, are welcome. For this Special Issue, research in the field of catalysis and green technologies associated with the use of polymer-containing nanoparticles, as well as catalysis by nanoscale systems of the processes of the synthesis and destruction of macromolecules, will be of considerable interest. Special attention will be paid to manuscripts devoted to aspects of the stabilization of nanoparticles by polymers. The subject of this Special Issue is the results of any fundamental and applied research related to the consideration of the properties of polymer-containing nanoparticles and their use in various industries.

Microheaters are used in several applications, including medical diagnostics, synthesis, environmental monitoring, and actuation. Conventional microheaters rely on thin-film electrodes microfabricated in a clean-room environment. However, low-cost alternatives based on conductive paste electrodes fabricated using printing techniques have started to emerge over the years. Here, we report a surprising effect that leads to significant electrode performance improvement as confirmed by the thorough characterization of bulk, processed, and conditioned samples. Mixing silver ink and PVA results in the solubilization of performance-hindering organic compounds. These compounds evaporate during heating cycles. The new electrodes, which reach a temperature of 80 °C within 5 min using a current of 7.0 A, display an overall 42% and 35% improvement in the mechanical (hardness) and electrical (resistivity) properties compared to pristine silver ink electrodes. To validate our results, we use the composite heater to amplify and detect parasite DNA from Trypanosoma brucei, associated with African sleeping sickness. Our LAMP test compares well with commercially available systems, confirming the excellent performance of our nanocomposite heaters. Since their fabrication relies on well-established techniques, we anticipate they will find use in a range of applications. Full article

The inclusion of particles in a polymeric substrate to achieve certain properties is a well-known practice. In the case of textile substrates, this practice may deeply affect the structure of the produced yarns, as even a filament with no textile applications can be obtained. In this manuscript, titanium dioxide (TiO2) particles were incorporated into polyester (PET) chips and the influence of these fillers on the properties of yarn and fabric, and the ultraviolet protection factor (UPF) was assessed. For this purpose, rutile and anatase crystalline forms of TiO2, as well as the size of the particles, were evaluated. Moreover, parameters such as mechanical properties, orientation of the macromolecules and thermal behavior were analyzed to ensure that the textile grade is maintained throughout the production process. The results showed that the inclusion of micro- and nanoparticles of TiO2 decreases the molecular weight and tenacity of PET. Also, although orientation and crystallinity varied during the textile process, the resulting heatset fabrics did not present important differences in those parameters. Finally, the attainment of textile-grade PET-TiO2 fabrics with UPF indexes of 50+ with both rutile and anatase and micro- and nano-sized TiO2 forms was demonstrated. Full article

The controllable delivery of drugs is a key task of pharmacology. For this purpose, a series of polymer composites was synthesized via the cross-linking of hyaluronate and a hyaluronate/polyacrylate mixture with Fe2O3 nanoparticles. The cross-linking imparts magnetic properties to the composites, which are more pronounced for the ternary hyaluronate/polyacrylate/γ-Fe2O3 composites compared with the binary hyaluronate/Fe2O3 composites. When dispersed in water, the composites produce microsized hydrogel particles. Circulation of the ternary microgels in an aqueous solution at a speed of 1.84 cm/s can be stopped using a permanent external magnet with a magnetic flux density of 400 T. The composite hydrogels can absorb the antitumor antibiotic doxorubicin (Dox); the resulting constructs show their cytotoxicity to tumor cells to be comparable to the cytotoxicity of Dox itself. The addition of the hyaluronidase enzyme induces degradation of the binary and ternary microgels down to smaller particles. This study presents prospectives for the preparation of magnetically controlled biodegradable polymer carriers for the encapsulation of bioactive substances. Full article

In order to expand the range of materials that can be used in outer space and in development of small spacecraft, ladder polyphenylsilsesquioxanes with different molar weights and the Nb-siloxane composites based on them were studied. The properties of the polymer films were studied, including tests in an oxygen plasma flow. Both initial and filled ladder polymers feature extremely low erosion coefficients in the region of 10–26 cm3/atom O at a high fluence of atomic oxygen of 1.0 × 1021 atom O/cm2. Ladder polyphenylsilsesquioxane films irradiated with atomic oxygen (AO) retain their integrity, do not crack, and exhibit good optical properties, in particular, a high transmittance. The latter slightly decreases during AO exposure. The Nb-siloxane filling retains the AO resistance and slight decrease in optical transmission due to diffuse scattering on the formed Nb-[(SiO)x] nanoparticles. Ladder polyphenylsilsesquioxanes demonstrate their suitability for creating protective, optically transparent coatings for small spacecraft that are resistant to the erosive effects of incoming oxygen plasma.

Abstract: In this study, we report an easy approach for production of aqueous dispersions of C60 fullerene with good stability. Maleic acid copolymers: poly(styrene-alt-maleic acid) (SM), poly(N-vinyl-2-pyrrolidone-alt-maleic acid) (VM) or poly(ethylene-alt-maleic acid) (EM) have been used to C60 stabilize and introduce carboxyl groups into the complex. Polymer conjugates were prepared by mixing a solution of fullerene in N-methylpyrrolidone (NMP) with an aqueous solution of the copolymer followed by exhaustive dialysis against water. The molar ratio of monomer units of maleic acid of the copolymer and C60 was 5/1 for SM and VM and 10/1 for EM. The volume ratio of NMP and water used was 1:1.2-1.6. The obtained structures can be converted to a solid state, and the C60 conjugates are soluble in NMP and water, but are practically insoluble and do not dissociate in non-polar solvents. The optical and physical properties of the preparations were characterized by UV-Vis spectroscopy, FTIR, DLS, TGA and XPS. Average diameter of the conjugates in water was 120-200 nm, and ξ-potential ranged from –16 to –20 mV. The bactericidal properties of the obtained nanostructures were studied in relation to the planktonic form of a number of conditionally pathogenic microorganisms. These fullerene conjugates were obtained under mild conditions and are easily produced; the functional groups of the polymer shell of fullerene can be easily modified.
