| description |
The discovery of graphene composites has driven changes among researchers because
of their unique properties. The aim of the present study is to synthesize graphene and
used as a filler in epoxy composites. The performance of synthesize graphene in epoxy
was compared with commercialize graphene. Graphene was synthesized using
modified Hummer’s method and spin coating was used to produce epoxy composites
with varying amount of filler loading. Analysis from Raman spectrum of synthesize
graphene showed an increase in intensity ratio (ID/IG) which indicates the decrease of
average size of the sp2 domains upon reduction of the GO. This is due to the loss of
carbon formation. Besides that, FTIR spectra showed that the graphite has been
successfully oxidized due to the presence of peak which referring to oxygencontaining
groups. The best graphene filler loading in epoxy composites was obtained
at 0.4vol% based on thermal conductivity measurement which indicate 37.5%
increment compared to unfilled epoxy. Additionally, graphene/epoxy composites
shows that the addition of filler in epoxy generally increase the electrical conductivity
value from 7.38 x 10-6 to 7.19 x 10-5 S/cm, which is two order of magnitude higher
than unfilled epoxy. Graphene/PEDOT:PSS with 1.0vol% loading exhibits 90% and
81% improvement in electrical and thermal conductivities, respectively compared to
graphene/epoxy composite. |
