Electrophoretic Deposition of Lignin Reinforced Polymer Coatings

Summary:Composite coatings based on PEEK and Lignin were obtained by EPD. The addition of Lignin had some beneficial effects, the most relevant being an increased coating adhesion on conductive substrates. Before using in EPD suspensions, Lignin was functionalised by a carbonyl group. This functionalisation produced chemical interactions between PEEK powder and Lignin, and, as a consequence, better results in terms of both EPD efficiency and adhesion coating. Moreover, the addition of Lignin increased the hydrophobicity of PEEK coatings when they were thermally treated at temperature lower than the melting point of PEEK.
