AbstractGraphite intercalation compounds (GIC) and exfoliated graphite (EG) as raw materials were prepared with flake graphite, concentrated sulphuric acid (H2SO4), potassium bichromate (K2Cr2O7) and peracetic acid (CH3CO3H) and characterized. Then, high-density polyethylene-exfoliated graphite (HDPE-EG) composites were fabricated with HDPE and EG via in situ synthesis technique in the different mass ratio, and their resistivity values (ohms/sq) were measured. Based on the resistivity values, it was discovered that HDPE-EG composite with the antistatic property could be fabricated while the mass ratio was 5.00 : 0.30. Last, HDPE-EG-aluminium hydroxide (HDPE-EG-Al(OH)3) composites were manufactured with HDPE, GIC and Al(OH)3 via the in situ synthesis-thermal expansion technique, and their resistivity values and limiting oxygen index (LOI) values were measured. Based on the resistivity values and LOI values, it was discovered that HDPE-EG-Al(OH)3 composite with the antistatic and fireproof property could be manufactured while HDPE, GICs and Al(OH)3 of mass ratio was 5.00 : 0.30 : 1.00. Otherwise, the petal-like morphology and structure of HDPE-EG-Al(OH)3 composite were characterized, which consisted of EG, HDPE and Al(OH)3.
