Embedded copper mesh coatings with low sheet resistance and high transparency were formed using a low-cost Cu seed obtained magnetron sputtering on cracked template, subsequent operations electroplating embedding in photocurable resin layer. The influence of the size optoelectric characteristics electromagnetic shielding efficiency wide frequency range is considered. In optimizing coating properties, 49.38 dB at 1 GHz, integral optical visible 84.3%, was obtained. meshes have been shown to...
The modern pace of scientific and technological development dictates unprecedented requirements for the speed information transfer. THz range is considered one most promising has been actively developing in recent years. Along with need to develop transmitting devices, demand shielding materials this range, including transparent ones, also growing. In work, we present two types composite films based on silver nanowires PEDOT:PSS. We characterized these terms optoelectrical parameters, as...
The paper considers the uniaxial orientation effect on structure and piezoelectric properties of vinylidene fluoride-tetrafluoroethylene copolymer ferroelectric films. films were exposed to stretching in temperature range from 20°C 60°C; then, they contact polarized under normal conditions. Temperature dependence electric strength was determined. longitudinal coefficient d33 values measured by quasi-static Berlincourt method. piezoresponse force microscopy (PFM) method used investigate film...
Nowadays, the Internet of Things (IOT), electronics, and neural interfaces are becoming an integral part our life. These technologies place unprecedentedly high demands on materials in terms their mechanical electrical properties. There several strategies for forming conductive layers such composites, e.g., volume blending to achieve a percolation threshold, inkjet printing, lithography, laser processing. The latter is low-cost, environmentally friendly, scalable way produce composites. In...
Composite nanomaterials have been prepared through thermal decomposition of palladium diacetate. The composite contains nanoparticles embedded in high-pressure polyethylene. materials were studied by a number different physico-chemical methods, such as transmission electron microscopy, X-ray diffraction, absorption spectroscopy, paramagnetic resonance, and EXAFS. average size the is 7.0 ± 0.5 nm. It shown that with decrease metal content polymer matrix decreased from 7 to 6 nm, coordination...
The study was devoted to the creation of transparent electrodes based on highly conductive mesh structures. analysis and reasonable choice technological approaches production such materials with a high Q factor (the ratio transparency electrical conductivity) were carried out. developed manufacturing technology consists formation grooves in substrate by photolithography methods, followed reactive ion plasma etching their metallization chemical deposition using silver mirror reaction....
The values of the surface potentials two sides films polyvinylidene fluoride, and its copolymers with tetrafluoroethylene hexafluoropropylene, were measured by Kelvin probe method. microstructures chains in surfaces on these evaluated ATR IR spectroscopy. It was found that observed differed studied films. Simultaneously, it from spectroscopy data both also differed. is concluded formation potential (self-polarized) ferroelectric polymers controlled microstructure layer. reasons for a...
Abstract Correlation between hardness and optical properties of diamond-like carbon (DLC) coatings is considered. Various methods for the characterization mechanical, chemical DLC are used; however, some these destructive, others non-destructive. It was found that proportional to their hardness. The mathematical expression allows calculate a coating according its refractive index proposed. Therefore, it possible avoid use destructive (such as nano-indentation technique) characterize coatings.
The purpose of this work was to research the resistance thin coatings effects corpuscular radiation, as well evaluation speed etching diamond-like films with different content diamond phase. There were two samples monocrystalline silicon DLC coating. To evaluate resistance, groups grooves etched on each sample. depth then measured calculate a relative ratio determined be four times that silicon.
For the first time, an environmentally friendly waste-free closed cycle for formation of EMI shielding materials that are promising 5G communications is considered. Based on proposed technological cycle, two types have been obtained; both significant prospects signal in all ranges allocated different countries communication. The type transparent conductive meshes with a transparency more than 80% and efficiency 40 dB S L bands about 30 K Ka bands. study reflection characteristics S, L, C,...
