چکیده انگلیسی
In this study, exfoliated graphite (EG) was used as filler to enhance the dielectric properties of composites, which are processed through microwave (MW) curing. EG was synthesized through MW irradiation technique. The detailed characterizations of as-synthesized EG were first carried out. Afterwards, the EG reinforced epoxy composites have been synthesized. The dielectric properties of composites as a function of EG content with and without MW heating were measured at a frequency of 2.45â¯GHz. The 3â¯wt% EG/epoxy composite shows an increase of about 43 and 81% in dielectric constant and loss factor, respectively. The dielectric properties are found to decrease after MW curing. Finally, the dynamical mechanical analysis was performed for MW cured samples including thermally cured samples. The glass transition temperature and storage modulus are found to improve by about 24â¯Â°C and 58%, respectively for MW cured 3â¯wt% EG/epoxy composite as compared to neat epoxy counterpart.
