dc.description.abstractBiochar (BC) from pine leaves was derived through slight modification in temperature and time as prescribed. After that graphene oxide (GO) was prepared from BC through slight modifications in stirring time, speed and concentrations of ingredients as prescribed in Hummer's method. A series of epoxy composites (ECs) were fabricated by dispersing carbonaceous fillers (CFs) with concentrations ranging 0-5% weight into a commercially available epoxy resin (CY-230) followed by curing with triethylene tetramine (TETA, HY-951). The CFs are nanographite (NG), BC, GO. The qualitative dispersion of CFs into cured epoxy was ascertained through atomic force microscopy (AFM) and scanning electron microscopy (SEM). The ECs were converted into different dimensions according to ASTM D specifications. The effect of CFs on their mechanical and thermal properties has been evaluated. With CFs concentration, a regular increase in hardness, tensile, flexural and compressive properties has been observed when CFs added up to 3% (w/w). This is attributed to homogeneous dispersion and good bonding between epoxy resin and CFs. The effect of CFs on thermo-oxidative stability of cured epoxy as well as ECs was investigated through simultaneous thermogravimetric-differential thermal analysisdifferential thermogravimetry (TG-DTA-DTG). The visco-elastic behaviour of epoxy composites was observed through dynamic mechanical analysis. This shows that the viscoelastic behaviour was enhanced with the addition of CFs and increase in frequency.
