Abstract
: Carbon nanotubes (CNT) and graphene nanoparticles (GNP) have been used as carbonaceous filler in epoxy composites based on the diglycidyl ether of bisphenol A (DGEBA) cured with tetra methyl diamine (TMD). Both CNT/epoxy and GNP/epoxy nanocomposites were subjected to ageing at 0%, 30%, 50%, 70% and 100% of relative humidity at room temperature for three weeks. Both composites show increasing water absorption percentage at higher relative humidity. Moreover, the GNP/epoxy nanocomposites showed a higher water absorption compared to CNT/epoxy nanocomposites. The dielectric constant increment of both nanocomposites is parallel to the water absorption properties. It is concluded that water absorption leads both to increase the dielectric constant of the epoxy resin.
期刊介绍：
The aim of the journal is to disseminate latest scientific ideas and findings in the field of physical sciences among scientists in Malaysia and international regions. This journal is devoted to the publication of articles dealing with research works in Chemistry, Physics and Engineering. Review articles will also be considered. Manuscripts must be of scientific value and will be submitted to independent referees for review. Contributions must be written in English and must not have been published elsewhere.
