How to make mylar conductive [Singapore] 

+++

Dear All,

I'm thinking of building a pair of electrostatic loudspeaker and is having problem the conductive mylar. Could anybody advice me how to coat the mylar sheet so that it can be conductive?
I'm thinking of conductive paint, but worries that it might be too heavy on the mylar.

Thank you very much

Activate it in a mixtrure of 41g sodium dichromate dissolved in 210mls of water with 770mls of concentrated sulphuric acid. Dip it in for between 5 and 30 seconds at 75-80C. The Mylar can then be activated for electroless metallisation and subsequent thickening as required.
