The antistatic functional material of HDPE/Shenfu coal were prepared. The physical and mechanical properties, compatibility, structure of interfacial interaction, and phase morphology of the polymeric alloy material were studied by differential scanning calorimetry, scanning electron microscopy and FTIR. The polymeric alloy materials have higher tensile strength, higher heat resistance and thermal stability, and more importantly, they have an antistatic function. The tensile properties exhibited positive deviation from linear additivity of properties, which is characteristic of partial compatible blends. Furthermore, the FTIR and DSC analysis show that the blends have some interfacial interaction. Observation of tear fracture surfaces of the blends showed fibril structure when the coal content was lower than 15% in the blends. This is attributed to a network-like structure of the HDPE phase of the blends and the interfacial interaction between coal surface functional groups and HDPE macromolecule chain.
