Abstract Our work aims to investigate the morphology and properties of natural rubber (NR) dispersed in a polystyrene/silica hybrid nanomatrix. The nanomatrix structure was formed by graft copolymerization vinyltriethoxysilane onto NR grafted with styrene. This composed nanosilica size less than 100 nm, incorporation polystyrene resulted outstanding mechanical viscoelastic properties. tensile s...

In this study a series of epoxy/silica nanocomposites were prepared by using nano silica particles which had different surface modifications. The morphology of the nanocomposite coatings was characterized by scanning electron microscopy SEM. The effects of the hydrophilic and hydrophobic feature of the nano particles on the Tg and anticorrosive properties of nanocomposite coatings were evaluate...

In the synthesis of nanoparticles, phenomenon agglomeration is an undesirable condition because particles formed can be larger. The use surfactants prevent occurrence this phenomenon. study, was studied in nanosilica from geothermal sludge. method applied sol-gel method. A 1 M sodium hydroxide (NaOH) solution used to prepare sol phase, while gel phase prepared at pH 5 using a 1.5 hydrochloric a...
