I am an electrical engineer which is why my chemical knowledge is limited. I am working with an electrohydrodynamic printer and it seems so far that inks based on nonpolar solvents are more suitable for this technology. Unfortunately there are not so many inks based on nonpolar solvents commercially available. That's why I had the question in mind, if it is possible to reduce the relative polarity of a e.g. water based nanoparticle suspension?
Thank you for your help in advance!
