I want no agglomeration of metal particles in the PLA- chlorofrom solvent solution. I am using solvent casting method to make the composite and finding the composite is not electrically conductive.
I want the composite to be electrically conductive. Any suggestions
I think that the non- ionic surfactants are suitable for dispersing metal particles in these two polar solvents.
For electrical conductivity you will need to match percolation conditions, i.e., in a 3D system a concentration above 26 % (volume). The surfactant won't affect this consideration.
Dear Krish,
In addition to these suggestions, don't forget to consider dispersing polymers created for engine oil additives. These have to disperse soot particles and metal wear particles. I suggested one such material (Chevron OLOA 11000) on ResearchGate many months ago. Perhaps if you search for that answer I posted, or look at the types of chemical functionalities that the internet shows you when you query it about OLOA 11000 then you may get some good ideas about other dispersants to try.
To also echo Dr. Goya, please be certain your system exceeds the percolation conditions for the morphology of particle and volume packing fraction in your application.
Best regards,
Mike Bender
