Dear Swapnil Narkhede thank you for asking this very interesting technical question. In addition to the useful links recommended by Carlos Araújo Queiroz and Abdelkader BOUAZIZ my suggestion would be to avoid the use of chromic acid due to the high toxicity of hexavalent chromium. In this context please have a look at the following potentially useful article entitled:

Chromium-free Etching and Palladium-free Plating of Plastics

https://www.pfonline.com/cdn/cms/1405%20Printable%20Version.pdf

This paper is freely available as public full text (see attached pdf file). A chromium-free etching process has also been eescribed in the following patent:

CHROME-FREE ETCH SOLUTIONS FOR CHEMICALLY RESISTANT POLYMER MATERIALS

Good luck with your research and best wishes, Frank Edelmann
