Voltage Insulator

<p>Research work of polymer nanocomposites in high voltage insulator becomes interest nowadays. Polymer based and nanofillers are the core components in polymer nanocomposites. By adding such a big amount of nanofiller it would enhance the electrical and mechanical properties of polymers.  However as for today, a little percentage of nanofiller concentration could dramatically enhanced the properties of the polymeric material. Recent research of graphene oxide (GO) nanofiller has brought to this project interest.  This paper presents several methods that have been published to development PMMA (poly methyl methacrylate)/GO nanocomposites and a simulation of PMMA/GO in order to investigate the potential distribution. </p>

Polymer nanocomposites reinforced by graphene oxide is one of the new research and developed from 2005 up to date. In this study, we had successfully fabricated polystyrene/graphene oxide nanocomposite by solution-based method. Graphite oxide was synthesized by the method of Hummers and exfoliated in solvent under the effect of ultrasound. The thermal and mechanical properties of PS/RGO nanocomposites were superitor to original polystyrene. In addition, our research has focused on the effect of graphene oxide to the rheological properties of polystyrene – one of the most important properties of polymer materials.

This work reports on the incorporation of Flint and Kaolin rocks powders in the cement mortar in an attempt to improve its mechanical properties and produce an eco-friendly mortar. Flint and Kaolin powders are prepared by dry mechanical milling. The two powders are added separately to the mortars substituting cement partially. The two powders are found to improve the mechanical properties of the mortars. Hardness and compressive strength are found to increase with the increase of powders constituents in the cement mortars. In addition, the two powders affect water absorption and thermal conductivity of the mortar specimens which are desirable for construction applications. Kaolin is found to have a greater effect on the mechanical properties, water absorption, and thermal conductivity of the mortars than Flint. This behavior is discussed and analyzed based on the compositional and structural properties of the rocks powders.
