Abstract: The ionic liquid was combined with a starch-based antistatic agent for use in antistatic modification of PE-HD, and the effect of two additives on the antistatic effect and mechanical properties of PE-HD-based compounds were investigated. The results indicated that a combination of ionic liquid and starch-based antistatic agent generated a good antistatic effect and long-term durability on the PE-HD compounds, and there was no reduction of tensile strength and notched impact strength found in the PE-HD compounds at a certain amount of ionic liquid and starch-based antistatic agent.

Key words: ionie liquid, starch-based antistatic agent, durability, mechanical property
