Hey Guys,
I am trying to sonicate Multiwall Carbon Nantoubes in Isopropyl Alcohol.
My current mixing ratio is 1mg of CNT /100 ml of IPA for about 2 hours.
The problem with my current method is that the CNTs coagulate very quickly
after I stop the sonication, I have tried to sonicate for a longer duration
but to no avail.

I am wondering if there is a problem with my concentration ratio, or if I
should  switch to some other solvent?
Alternately please suggest sonication recipies of your own.

Thanking you in anticpation,

Sincerely,
Husein Rokadia
