“…The addition of inorganic particles such as hectorite, 27,28 smectite, 29 fumed silica, 30,31 and montmorillonite clay (MMT) [32][33][34] provides both an increase in the ionic conductivity and an improvement in the mechanical properties. Electrolytes containing silica nanoparticles have also been used to assemble dye-sensitized solar cells, leading to remarkable performances.…”

Neste trabalho um eletrólito polimérico nanocompósito baseado em uma argila do tipo montmorilonita e um polímero derivado do poli(óxido de etileno) plastificado com -butirolactona foi preparado e caracterizado. Apesar da adição de plastificantes à matriz polimérica aumentar a condutividade iônica de eletrólitos poliméricos, a adição de grande quantidade desses aditivos compromete as propriedades mecânicas do sistema, de tal maneira que o ganho em condutividade não compense a perda na natureza "sólida" do meio eletrolítico. Filmes do eletrólito nanocompósito contendo diferentes concentrações de argila foram caracterizados por análise térmica e mecânica e por espectroscopia de impedância eletroquímica. A adição de montmorilonita resultou numa melhora das propriedades mecânicas do eletrólito, além de contribuir para um aumento da condutividade iônica do sistema. O eletrólito compósito foi aplicado em uma célula solar de TiO 2 /corante pela primeira vez, resultando em um dispositivo com eficiência superior a 3% sob irradiação de 10 mW cm -2 .In this work we report for the first time the preparation and characterization of a novel composite polymer electrolyte based on montmorillonite clay and a poly(ethylene oxide) derivative plasticized with -butyrolactone and its application in dye sensitized solar cells. Although the plasticizers enhance the ionic conductivity of the polymer electrolytes, they compromise the mechanical stability of the whole system and make the practical application of these devices difficult. Films with composite polymer electrolytes containing different clay content were analyzed by thermal and mechanical analysis and electrochemical impedance spectroscopy. We observed that the addition of the inorganic particles to the polymer matrix promotes not only an enhancement in the mechanical properties but also contributes to the increase the of ionic conductivity of the system. A solid-state dye-sensitized solar cell was assembled for this first time with the electrolyte containing montmorillonite clay, displaying efficiencies higher than 3% at 10 mW cm -2 .Keywords: MMT clay, composite polymer electrolyte, ionic conductivity, dye sensitized solar cells IntroductionSince Grätzel's announcement of the first dye-sensitized nanocrystalline solar cells (DSSC) 1 as promising, low cost, clean, and highly efficient devices for solar energy conversion, many groups have focused their efforts on improving and comprehending this technology in its different aspects. The liquid electrolyte usually employed in this cell is still a drawback for long-term practical operation due to electrolyte leakage or evaporation. It makes the large scale production difficult and causes substantial problems to bring DSSC onto the market. To overcome these problems, many research groups have been searching for alternatives to replace the liquid electrolytes, such as inorganic or organic hole conductors, 2-4 ionic liquids, 5,6 polymer 7-9 and gel electrolytes. [10][11][12][13][14] Our group has been working on DSSC using polymer el...

Ultra-lightweight heat resisting poly(methyl methacrylate) (PMMA)/graphite microspheres were successfully prepared via in situ suspension polymerization. The Fourier transform infrared and X-ray powder diffraction results confirmed the successful preparation of the composite microspheres. Field emission scanning electron microscope analysis illustrated that the graphite particles were dispersed in microspheres and the PMMA/graphite composite microspheres had good sphericity and roundness. Furthermore, density analysis indicated that the apparent density of composites microspheres was about 1.055-1.135g/cm 3 which was suitable for the transmission with water carrying. The results from thermodynamic test revealed that the thermal stability of the composite was significantly improved with increasing graphite content, which could be used as ultra-lightweight proppant in deep underground. In addition, the crushing rate decreased to 0.5% with graphite ratio of 3.0% at the pressure of 69 MPa. Therefore, PMMA/Graphite composite microspheres exhibit a promising application in petroleum or gas exploitation as water carrying fracturing proppants.
