Investigators from Indian Institute of Science Target Composite Materials

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Composite Materials. According to news reporting originating in Bangalore, India, by VerticalNews journalists, research stated, "In this study, mesoporous silica-cyclic olefin copolymer nanocomposite films were fabricated by solution casting. With an increase in silica loading, the stiffness of the matrix increased."

The news reporters obtained a quote from the research from the Indian Institute of Science, "The nanocomposite film shows increased strain to failure with moisture after aging by matrix plasticization. The storage modulus and loss factor for samples with silica content show better results compared with pristine polymer, as indicated by dynamic mechanical analysis. The interaction between filler-polymer chain exhibit hydrophobicity compared to the neat polymer. Water absorption studies at room temperature and near the T-g of the polymer (similar to 64 degrees C) were carried out. The nanocomposites up to 4 wt% filler reduces the water diffusion by forming hydrogen and chemical bonding."

According to the news reporters, the research concluded: "The result by calcium degradation test method for moisture permeability and Schottky structured organic device encapsulation under weathering condition confirms the effective reinforcement effect of silica particles in the matrix."
