Abstract

In this study, aqueous dispersions of partially crystalline PVDF nanoparticles (NPs) were obtained employing hydrophobin (HFB), an amphiphilic film-forming protein able to film hydrophobic surfaces. Dynamic Light Scattering (DLS) and Transmission Electron Microscopy (TEM) analysis of PVDF-HFBII aqueous dispersions confirmed the HPBII ability to film PVDF hydrophobic NPs. Freeze-dried PVDF-HFBII bio-nanocomposites were shown to be effectively re-dispersible in water. An aqueous dispersion of PVDF NPs may have an impact on the applications of this polymer in the perspective of the development of environmentally friendly coating methods.
