Abstract EN
Nanocomposites physical properties unexplainable by general mixture laws are usually supposed to be related to interphases, highly present at the nanoscale.
The intrinsic dielectric constant of the interphase and its volume need to be considered in the prediction of the effective permittivity of nanodielectrics, for example.
The electrostatic force microscope (EFM) constitutes a promising technique to probe interphases locally.
This work reports theoretical finite-elements simulations and experimental measurements to interpret EFM signals in front of nanocomposites with the aim of detecting and characterizing interphases.
According to simulations, we designed and synthesized appropriate samples to verify experimentally the ability of EFM to characterize a nanoshell covering nanoparticles, for different shell thicknesses.
This type of samples constitutes a simplified electrostatic model of a nanodielectric.
Experiments were conducted using either DC or AC-EFM polarization, with force gradient detection method.
A comparison between our numerical model and experimental results was performed in order to validate our predictions for general EFM-interphase interactions.
