Thank you very much for your reply. Would you please tell me how much PVA has to be added in how much water to make the perfect solution? Besides, can the stirring be done at room temperature? When shall I add my nanoparticles? Shall I add PVA and the nanoparticles together or I will add the nanoparticles after PVA gets dissolved completely?
You take PVA in in distilled water depending upon your requirement. Then heat this solution with stirring at arount 90 degree for complete dissolution of PVA . Then cool it to the room temperature.
Simultaneously you prepared you dispersed your nanoparticle in methanol then mixed it with PVA solution .
