This research was done to study the effects of graphene nanoplatlet (GNP) hybridization on the mechanical, morphological and thermal properties of Sansevieria trifasciata-natural rubber-high density polyethylene (STF-NR-HDPE) composite. Processing Of STF-NR-HDPE with modification Of GNP was done by using an internal mixer. Filler loading of 20 % STF into the matrix (NR/HDPE) was introduced in this study with variation of GNP composition used was around 1-10 wt. %. Composite blends obtained were pressed with a hot-press machine to produce samples with 1 mm and 3 mm of thickness. Samples were evaluated via tensile test, Izod impact test, X-Ray Diffraction (XRD) and differential scanning calorimeter (DSC). Morphological study was done by using afield emission scanning electron microscope (FESEM). The results showed that tensile strength and impact strength had decreased at the early stage Of GNP addition but the values keep increasing after more than 5 wt. % of GNP were added to the system. Generally, tensile modulus showed an increasing trend with the increment of filler loading. Thermal analysis with DSC did not show any obvious trend towards materials' thermal behavior. This is due to the good thermal stability characteristic of STF.
