Comparison of rheological, mechanical, electrical properties of HDPE filled with BaTiO3 with different polar surface tension

- The non-polar and short vinyl groups can greatly reduce G′ of HDPE composites.
- Long chains on BaTiO3 surface enhance the interaction of BaTiO3 with HDPE.
- Polar amino groups on BaTiO3 surface raise the interaction of BaTiO3 with HDPE.
- Polar amino groups can boost the dielectric constant of HDPE composites.
- The potential use in electronic equipment of the KH550 composites is obtained.
