“…The simultaneous processing allowed effective intermixing of inorganic and polymer matrices, while the presence of MAPTMS in reaction mixture enabled formation of covalent linkage between inorganic and polymeric phases. [ 36,37 ] As result, structurally and compositionally homogeneous hybrid membranes consisting of interpenetrated networks of inorganic and polymeric phases being covalently linked with each other were obtained under optimized conditions. Present work provides a systematic analysis of physico–chemical behavior of a series of polymeric and hybrid membranes with respect to 1) varied composition of the monomer mixture (AN:AA:AMPS ratio); 2) varied composition of sol–gel precursors (TEOS:MAPTMS ratio); and 3) varied fraction of the sol–gel component in reaction mixture (see Table 1).…”

“…It should be pointed out that the MAPTMS is frequently used as a bonding agent in various mixtures which are cured via a free radical mechanism. [ 37,43,44 ] Moreover, the fabrication of UV‐cross‐linkable hybrid coatings made of a two‐component sol–gel mixture consisting of MAPTMS and TEOS has been reported as well. [ 45 ] Therefore, formation of covalent linkage between organic and silica component is also expected in present system.…”

The preparation of hybrid proton conductive membranes that comprise of covalently linked interpenetrating polymer and inorganic networks is reported. The hybrid membranes are synthesized via simultaneous photo‐initiated polymerization and sol–gel processing. The simultaneous processing permeates fabrication of the membranes that comprises covalently cross‐linked polymeric and inorganic networks. The membranes are characterized by attenuated total reflectance‐Fourier transform infrared spectroscopy, scaning electron microsopy, thermogravimetric analysis, differential scanning calorimetry, in order to confirm their chemical composition, structure, and morphology. An addition of 3‐methacryloxypropyl trimethoxysilane into the sol–gel composition allows the formation of covalent linkages between polymeric and inorganic networks, which facilitates a uniform distribution of the molecular components across the fabricated membranes. The incorporation of the silica network leads to an increase in water retention and proton conductivity of hybrid membranes as compared to their purely polymeric analogues.

“…Most of these HCs are based on the dispersion of dense, inorganic fillers into a polymeric host matrix. Their mechanical, optical, and chemical properties can be tuned depending on the chemical nature, quantity, and dispersion of the constitutive elements, as this has been described in Vlassak et al 18 In the framework of the LOMID project, two dedicated HC formulations, called HC1 and HC2, have been developed with the aim of providing the coating an excellent processability and a good scratch resistance once hardened by UV light exposure and annealing. HC1 and HC2 differ in their composition: HC1 is based on a silica polymeric network, whereas HC2 is based on a dispersion of dense silica nanoparticles, Figure 4.…”

Technical background for CMOS substrate thinning of CEA‐LETI (historically developed for through silicon via technology as well as for more recent activity to provide curved image sensors, for IR as well as for visible spectra) has been applied to realize curved OLED‐based microdisplays. It will be shown that test OLEDs made onto silicon wafers as well as 873 × 500 WVGA, 0.38″ diagonal, and an innovative 1920 × 1200 WUXGA, 1″diagonal, CMOS‐based microdisplays can be curved at R = 45 mm radius of curvature (1D) with no negative impact onto the circuit electrical characteristics. This feature can allow significant innovation on the system and application because it can help to redesign simpler and lighter optical engine systems, in the same manner as for curved image sensors. These results can be obtained owing to the integration of a new protective hard coat layer that has been used in conjunction with a robust thin‐film encapsulation to protect OLEDs from mechanical ingress (from process steps and handling) and oxidizing gas of the atmosphere, respectively. Results have been produced within the framework of the EU‐funded, H2020 project, called Large cost‐effective OLED MIcroDisplays (LOMID and their applications).

“…Among these methods, coating with nano-SiO 2 has gained much attention due to its attractive features of high absorption of ultraviolet light, transparency in the visible region, a stable mesoporous structure, eco-friendliness, low cost, excellent biocompatibility, and nontoxicity in nature [18,19,20]. As a versatile liquid-based method for synthesizing nanoparticles and oligomers inorganic networks [21], the sol-gel process has shown great advantages in obtaining nano-SiO 2 from the hydrolysis and condensation of alkoxide precursors [22] and has a wide range of applications in hybrid coating materials [23]. Since the sol-gel method is a simple procedure, it has attracted great interest in the fields of material synthesis and polymeric modification.…”

Aramid fibers (AFs) with their high Young′s modulus and tenacity are easy to degrade seriously with ultraviolet (UV) radiation that leads to reduction in their performance, causing premature failure and limiting their outdoor end use. Herein, we report a method to synthesize nano-SiO2 on AFs surfaces in supercritical carbon dioxide (Sc-CO2) to simultaneously improve their UV resistance, thermal stability, and interfacial shear strength (IFSS). The effects of different pressures (10, 12, 14, 16 MPa) on the growth of nanoparticles were investigated. The untreated and modified fibers were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). It was found that the nano-SiO2-decorated fibers exhibited improvement of thermal stability and mechanical properties, and the IFSS of the nano-SiO2 modified fibers increases by up to 64% compared with the untreated fibers. After exposure to 216 h of UV radiation, the AFs-UV shows a less decrease in tensile strength, elongation to break and tensile modulus, retaining only 73%, 91%, and 85% of the pristine AFs, respectively, while those of AFs-SiO2-14MPa-UV retain 91.5%, 98%, and 95.5%. In short, this study presents a green method for growing nano-SiO2 on the surface of AFs by Sc-CO2 to enhance the thermal stability, IFSS, and UV resistance.
