Investigation of graphene flake dispersion inside a polymer matrix

Oana Istrate

Scientific Case

The properties of a polymer nanocomposite depend on the dispersion degree of the nanofillers inside the polymer matrix. The dispersion, exfoliation and flake size of the nanofillers become of greater importance when barrier and corrosion properties are evaluated. In this work we are investigating the barrier and anti-corrosion properties of polymer/graphene nanocomposite formulations manufactured with different flake sizes and how the dispersion of the graphene flakes influences the aforementioned properties.

Experiment Design

For this project Carl Zeiss Versa XRM 520 HMXIF should be used. The features required to be identified are between a few microns and a few tens of microns or even larger if agglomerations are present. In order to be able to identify the aforementioned features phase contrast will have to be used.

Sample & Safety

The samples are films with a thickness varying from a few microns to approximately 100 ┬Ám. They include a polyester based polymer matrix and graphene nanoplatelets (XGnP 5M, 15M and 25M).
