“…The acrylate primer coatings, which can be effective to improve the adhesion of ITO films, were curtaincoated on PMMA sheets and cured at 85 • C for 2 h. The thickness of the acrylate primer coatings used in our experiment was approximately 3 µm. More details of preparation can be found elsewhere [21]. Deposition of the ITO thin films was performed by a direct current magnetron sputtering method at room temperature from a sintered conducting indium tin oxide ceramic target (In 2 O 3 :SnO 2 = 90:10 wt.%, Φ70 mm × 5 mm).…”

“…Transparent acrylic coatings present a good compatibility with conductive films and PMMA substrates, but have worse anti-scratch properties [20]. Different to PU and acrylic coatings, silicone-based coatings with hard Si-O-Si net structures, provide higher hardness and impact resistance, which enhances crack prevention and scratch resistance [21]. The mechanical properties and scratch resistance of organic transparent coatings directly deposited on polyester substrates (PC, PMMA, PET, etc.)…”

Transparent conductive films (TCFs) have received much research attention in the area of aeronautical canopies. However, bad wear, corrosion resistance and weak erosion performance of TCFs dramatically limit their scalable application in the next-generation aeronautical and optoelectronic devices. To address these drawbacks, three types of optically transparent coatings, including acrylic, silicone and polyurethane (PU) coatings were developed and comparatively investigated ex situ in terms of Taber abrasion, nanoindentation and sand erosion tests to improve the wear-resistance and sand erosion abilities of ITO-coated PMMA substrates. To elucidate the sand erosion failure of the coatings, the nanoindentation technique was employed for quantitative assessment of the shape recovery abilities under probe indentation. Results show that the PU topcoats can greatly enhance the sand erosion properties, which were superior to those of acrylic and silicone topcoats. This result can be attributed to the good toughness and self-healing properties of PU topcoats. Additionally, high hardness and good Taber abrasion properties of the ITO films and silicone topcoats did not have an obvious or affirmatory effect on the sand erosion abilities, based on their brittleness and irreparable properties under sand erosion.

“…Indium-tin oxide (ITO), a heavily doped and highly degenerated n-type semiconductor with high carrier concentration (~10 21 cm −3 ) [ 4 , 5 , 6 ], is one of the most widely used transparent conductive oxides (TCO) due to unique combination of excellent electrical conductivity, optical transparency and good mechanical properties and relatively good chemical stability [ 7 , 8 , 9 ]. Although various new materials, such as tin dioxide (SnO 2 ) [ 10 ], zinc oxide (ZnO) [ 11 , 12 ], indium zinc oxide (IZO) [ 13 ], conductive nano-silver wire [ 14 ], have been applied in industry, ITO is still the main choice for conductive optical [ 15 ]. Its excellent photoelectric performance demonstrate potential in high efficiency optoelectronic devices including solar cells [ 16 ], touch screens [ 17 ], panel displays [ 17 ], organic light emitting diodes [ 18 ], electro-optic switches [ 19 ], liquid crystal devices (LCDs) [ 20 ], but also sensors for electronic skins [ 12 ] or thin film photovoltaics [ 21 ].…”

High Power Impulse Magnetron Sputtering of In2O3/Sn Cold Sprayed Composite Target

High Power Impulse Magnetron Sputtering (HiPIMS) was used for deposition of indium tin oxide (ITO) transparent thin films at low substrate temperature. A hybrid-type composite target was self-prepared by low-pressure cold spraying process. Prior to spraying In2O3 and oxidized Sn powders were mixed in a volume ratio of 3:1. Composite In2O3/Sn coating had a mean thickness of 900 µm. HiPIMS process was performed in various mixtures of Ar:O2: (i) 100:0 vol.%, (ii) 90:10 vol.%, (iii) 75:25 vol.%, (iv) 50:50 vol.%, and (v) 0:100 vol.%. Oxygen rich atmosphere was necessary to oxidize tin atoms. Self-design, simple high voltage power switch capable of charging the 20 µF capacitor bank from external high voltage power supply worked as a power supply for an unbalanced magnetron source. ITO thin films with thickness in the range of 30–40 nm were obtained after 300 deposition pulses of 900 V and deposition time of 900 s. The highest transmission of 88% at λ = 550 nm provided 0:100 vol. % Ar:O2 mixture, together with the lowest resistivity of 0.03 Ω·cm.

“…In general, the systems use high concentrations of particles, 21,22 doping the polymer by metal oxides 23 or obtaining nanoparticles in situ. 14,24 Although such routes are promising, they lead to higher costs of obtaining the materials, which encourages new routes for obtaining them. Thus, the evaluation of the impact of hybrid systems of nanocomposites obtained via solution can represent an easier, faster, and less costly way to obtain these materials.…”

The development of new materials for obtaining ophthalmic lenses is a subject of great interest due to the great necessity of corrective lenses uses. The application of the lenses based on polymeric material that guarantees greater lightness and less risk of breakage, ensuring greater comfort to users of glasses. The use of nanoparticles in polymer nanocomposites can generate different properties in the final material, mainly when used in hybrid systems in which synergistic effects can be produced. Thus, the present work aimed to evaluate the optical properties of systems with poly(methyl methacrylate) and oxide nanoparticles (silica, zinc, zirconium, and titanium). The systems were characterized in terms of their optical behaviors (refractive index, transmittance, and color change) and mechanical behaviors (nanoindentation, and tensile strength). The results showed that silica-based systems tended to have greater transparency but generate lower refractive indexes. Systems containing zirconia, titanium, and zinc have a higher refractive index and smaller transparency than systems containing silica. Besides, the use of zirconia and titanium increases the nano-hardness and elastic modulus. The results showed that the use of these nanoparticles in binary systems leads to obtaining materials with higher refractive index, greater transparency, and best mechanical behavior. The combination of the nanoparticles also led to a better dispersion, reducing the impact on the color system and improve transparency. In this way, the materials developed using small amounts of fillers and present highly promising for the development of thinner, more resistant to scratching due to high hardness and higher transparent lenses.
