The GPC and NMR spectroscopic data confirmed a moderate to high degree of polymerization while microscopic pictures showed well-defined arrangements of fullerenes. The FTIR studies indicated that the product is free from starting azide materials, whereas thermogravimetric analysis data suggested a good stability. Band gap of the material was determined using UV-Vis spectroscopy, cyclic voltammetric techniques and compared with computational investigation. The fullerene copolymer was fabricated as acceptor material in a bulk heterojunction photovoltaic cell. (C) 2016 Elsevier Ltd.

The effective incorporation of amine modified bentonite nanoclays (AMB) in the PVA matrix leads to increase in thermal stability, stress-strain properties. The effect of addition of functionalized nanoclays in PVA matrix exhibits intercalated nanocomposite structure. The thermal decomposition (Td) temperature of the composites increases up to 30 °C, than pristine PVA. The morphology influences were studied by TEM. These clay nanocomposite films could be useful for wound dressing material and for enhancing the moisture absorbance properties.1 aRajeswari, B.1 aMalarvizhi, N.1 aElumalai, Deenadayalan1 aJaisankar, Sellamuthu, N.  uhttps://library.ncl.res.in/content/influences-functionalized-nanoclays-morphology-and-mechanical-properties-polyvinyl-alcohol
