Dear Gedvidas Bikulcius,

Try to coat polypyrrole on aluminium, check for the desired output.

Thanks

Dr. Anamika

Pierluigi Traverso

Dear Dr. Gedvidas Bikulcius ,

in general - as I don't know the specific application - you can obtain a black anodization directly (e.g. Hard Anodization) or through a subsequent "sealing" and pigmentation treatment. This second step could direct your choice taking into account the limitation of reflected light.

The processes are almost all patented and guarantee high-level technical specifications that can only be obtained by knowing in detail the type of aluminum and its use.

Useful indications could come from those who carry out surface treatments e.g. the MICRON COATINGS Group of which I am attaching the link: https://www.microncoatings.it/en/anodizing/

Good luck and my best regards, Pierluigi Traverso.
