Local Dielectric Property Detection of the Interface between Nanoparticle and Polymer in Nanocomposite Dielectrics.

ABSTRACT: The interface between nanoparticles and polymer matrix is considered to have an important effect on the properties of nanocomposites. In this experimental study, electrostatic force microscopy (EFM) is used to study the local dielectric property of the interface of low density polyethylene (LDPE)/TiO₂ nanocomposites at nanometer scale. The results show that the addition of TiO₂ nanoparticles leads to a decrease in local permittivity. We then carry out the finite element simulation and confirm that the decrease of local permittivity is related to the effect of interface. According to the results, we propose several models and validate the dielectric effect and range effect of interface. Through the analysis of DSC and solid-state NMR results, we find TiO₂ na
