Preparing the Solution - Dissolve PVA and PVP: Combine the PVA and PVP with distilled water in a beaker. The amount of water remains the same (100ml) to ensure the solution is not too dilute. Heat the mixture while stirring continuously. Use a water bath or a microwave for controlled heating. The goal is to dissolve both the PVA and PVP completely without boiling the water. This process might take some time, so patience is key. Heating should be done until you reach a homogeneous, clear solution, typically around 90°C. - 2. Adding Graphite and Boric Acid - Cool Down the Solution: Allow the solution to cool to about 50°C to prevent the premature reaction of boric acid. - Incorporate Graphite Powder: Gradually add the graphite powder to the solution, stirring continuously to avoid clumps and ensure even distribution. - Add Boric Acid: Slowly incorporate the boric acid into the mixture.
