| Abstract: |
Polyimide-copper composite coatings were fabricated by solution precursor flame spray through controlling the reaction of dianhydride with diamine dissolved in dimethylformamide solvent. Copper nanoparticles (<300 nm) were added in the starting polyimide precursor for the coating deposition. Microstructure, surface characteristics, corrosion resistance and biological properties of the coatings were examined. Antifouling performances of the constructed layers were assessed by measuring adhesion behaviors of typical proteins, bacteria, and marine algae on their surfaces. Even distribution of the inorganic nano particles endows the polyimide coatings with special capsular structure, exciting hydrophobicity and antimicrobial antifouling performances. The strategy of depositing the composites on any engineering surfaces by utilizing the inert properties of polyimide and antifouling nature of copper gives a new insight into design and construction of environment-friendly marine antifouling coatings for long-term versatile applications.
