Graphite intercalation compounds (GIC) and exfoliated graphite (EG) as rawmaterialswere preparedwith flake graphite, concentrated sulphuric acid (H2SO4), potassium bichromate (K2Cr2O7) and peracetic acid (CH3CO3H) and characterized.Then, highdensity polyethylene-exfoliated graphite (HDPE-EG) compositeswere fabricatedwithHDPE andEGvia in situ synthesis technique in the differentmass ratio, and their resistivityvalues (ohms/sq)weremeasured.Based on the resistivityvalues, itwas discovered thatHDPEEGcompositewith the antistatic propertycould be fabricated while the mass ratio was 5.00 : 0.30. Last, HDPE-EG-aluminiumhydroxide(HDPE-EG-Al(OH)3) compositesweremanufacturedwithHDPE,GIC and Al(OH)3viatheinsitusynthesis-thermal expansiontechnique, andtheir resistivityvalues andlimitingoxygenindex (LOI) valuesweremeasured. Based on the resistivity values and LOI values, it was discovered that HDPE-EG-Al(OH)3 compositewith the antistatic and fireproof propertycouldbemanufacturedwhileHDPE, GICs andAl(OH)3 ofmass ratiowas 5.00 : 0.30 : 1.00. Otherwise, the the petal-likemorphologyand structure ofHDPE-EG-Al(OH)3 compositewere characterized, which consisted ofEG,HDPEandAl(OH)3.
