hello

sorry my english is not very well!

i make a training course on a loboratory working on thin film (GCM
Polytechniques Montreal)
i work on treatment by corona gas discharge on polymer layer
(PC,PE,PMMA)

i am looking for some information about:

1)what is doing on the polymer layer during the treatment?

2)there is structural modification?(it is like static electricity)

3)what is the best way to analyse the layer? (X-ray diffractometer,
IR-spectroscopy, AFM, xps, ...)

4)how i can "clean" the layer from static charge?
(i knwon i can use a ionizer but i already have a corona system and i
don t want to buy a other device.)
(someone told me about vapor but i find that strange)

I'm looking forward to receive the information or web site link's.
Thanks.
