Hello,

As PVA is a water-soluble polymer, it is recommended to use water to disperse the CNT. You can use ultrasonication to assist the dispersion of the nanoparticles in the water (There are several papers about that in the scientific literature). So, it will be possible to mix the CNT/water dispersion in a PVA/water solution without degrading the polymer (You can find some works about this in the scientific literature, too).

If the distribution and dispersion of the CNT on PVA matrix are important to you, I recommend characterizing the obtained nanocomposite with electronic microscopy techniques like Transmission Electronic Microscopy or Scanning Electronic Microscopy (of the fracture).

Good luck with your project!

Sincerely.
