“…Similarly, the PMMA/CeO2 hybrid systems were prepared using conventional single-screw melt compounding and were systematically investigated as a function of the amount and thermal treatment temperature of inorganic nanoparticles. 1 H NMR spectra revealed only the presence of electrostatic interactions between the PMMA and CeO2 nanoparticles. The XRD analysis showed that the incorporation of CeO2 into the polymer did not change the amorphous structure of the PMMA.…”

“…Transmission IR experiments were carried out under environmental conditions with 10 scans at a resolution of 4 cm´1. To determinate the interaction between the organic and inorganic phases, 1 Crystalline phase identification of the CeO 2 powders and nanocomposites was performed using a D8 Advance Bruker X-ray diffractometer (Bruker AXS GmbH, Berlin, Germany) with Cu-Kα monochromatic radiation (Bruker AXS GmbH, Berlin, Germany). The XRD patterns were collected in the 2θ range from 10 to 90˝at room temperature.…”

“…In the last years, there has been an increased tendency to use thermoplastic polymers such as polycarbonate (PC), polymethylmethacrylate (PMMA) and polyethylene-tetrafluoroethylene (PTFE) in diverse industrial applications due to their low weight and high transparency [1,2]. PMMA is one of the most commonly used thermoplastic polymers in the construction industry because of its excellent optical properties (it transmits light in the 360-1000 nm range almost without loss [3]), impact and shatter properties (compared to inorganic glass), and relatively high weathering resistances.…”

Thick and homogeneous hybrid film systems based on poly(methyl methacrylate) (PMMA) and CeO2 nanoparticles were synthesized using the melt compounding method to improve thermal stability, mechanical and UV-shielding properties, as well as to propose them for use in the multifunctional materials industry. The effect of the inorganic phase on these properties was assessed by using two different weight percentages of synthesized CeO2 nanoparticles (0.5 and 1.0 wt %) with the sol–gel method and thermal treatment at different temperatures (120, 235, 400, 600 and 800 °C). Thereafter, the nanoceria powders were added to the polymer matrix by single screw extrusion. The absorption in the UV region was increased with the crystallite size of the CeO2 nanoparticles and the PMMA/CeO2 weight ratio. Due to the crystallinity of CeO2 nanoparticles, the thermal, mechanical and UV-shielding properties of the PMMA matrix were improved. The presence of CeO2 nanostructures exerts an influence on the mobility of PMMA chain segments, leading to a different glass transition temperature.

“…Therefore, the design of new energy efficient materials and technologies is crucial to meet goals such as the Net‐Zero Energy Commercial Building Initiative (CBI) put forward by the U.S. Department of Energy (DOE). There has been tremendous interest in economizing energy uses in buildings through house roofing, skylights, and architectural windows . For example, smart windows have been developed, which become opaque to block or reflect sunlight on scorching days to save air conditioning costs, and return to a transparent state at a low lighting condition to improve light harvesting and capture free heat from the sun .…”

A Robust Smart Window: Reversibly Switching from High Transparency to Angle‐Independent Structural Color Display

et al. 2015

View full text Add to dashboard Cite

A smart window is fabricated from a composite consisting of elastomeric poly(dimethylsiloxane) embedded with a thin layer of quasi-amorphous silica nanoparticles. The smart window can be switched from the initial highly transparent state to opaqueness and displays angle-independent structural color via mechanical stretching. The switchable optical property can be fully recovered after 1000 stretching/releasing cycles.

“…The term metha indicates an additional methyl group attached to the α-carbon of acrylic acid with the formula CH 2 =C(CH 3 )COOCH 3 . MMA is a monomer used to produce poly(methyl methacrylate) (PMMA), which has been used in various research and applications such as undissolved surface coatings, adhesives, sealants, impact modifiers, emulsion polymers, surgical bone cements, packaging applications and other construction materials [19][20][21][22][23][24]. MMA is an organic compound with the formula CH 2 =C(CH 3 )COOCH 3 .…”

A liquid electrolyte based on binary solvent systems of ethylene carbonate (EC), dimethyl carbonate (DMC) and lithium bis(trifluoromethane)sulfonimide (LiTFSI) incorporated with methyl methacrylate (MMA) monomer is synthesized. The ionic conductivity (σ) ∼2.16×10 −3 S cm −1 at room temperature is found for the 0.058 mol kg −1 of LiTFSI. Viscosity measurements are carried out within temperature ranges 25-40°C. The activation energy E a of the flow process (viscous flow) is calculated using Arrhenius equation. Structural properties of the liquid electrolyte are studied using Fourier transform infrared (FTIR) spectroscopy. Electrochemical supercapacitors are then assembled using the liquid electrolyte and activated carbons as electrode materials. The electrochemical properties of the supercapacitors are investigated using cyclic voltammetry, cyclic charge-discharge and electrochemical impedance spectroscopy techniques. It is found that the supercapacitors exhibited specific capacitance ∼46.5 F g −1 at 10 mV s −1 . The long cycling stability of the supercapacitor containing monomer-based liquid electrolyte confirms the electrochemical stability of the electrolyte.
