Create an illustration depicting the step-by-step preparation of a polyvinyl alcohol (PVA) solution for electrospinning. The image should include the following elements:
Step 1: Measuring Ingredients
Show a laboratory scale with containers labeled 'PVA Powder' and 'Deionized Water'. Indicate the amounts being measured (e.g., 8g of PVA and 100mL of water).
Step 2: Mixing
Illustrate a beaker on a magnetic stirrer with a stir bar inside. The beaker should contain the PVA powder being added to the water. Label this step as 'Mixing at Room Temperature'.
Step 3: Heating
Depict a hot plate with the beaker on it, showing a thermometer indicating a temperature of around 85-95°C. Include steam rising from the beaker to indicate heating.
Step 4: Stirring
Show the magnetic stirrer in action, stirring the solution for approximately 30-60 minutes until fully dissolved. Include bubbles forming on the surface to indicate vigorous mixing.
Step 5: Cooling
Illustrate the beaker after heating, now cooling down to room temperature, with arrows indicating the cooling process.
Step 6: Final Solution
Display a clear PVA solution in the beaker, ready for electrospinning, with labels indicating 'Final PVA Solution' and 'Ready for Electrospinning'.
Technical Terms:
Include labels for each step with technical terms such as 'Hydration', 'Dissolution', 'Homogeneity', and 'Electrospinning Preparation', Illustration showing preparation of polyvinyl alcohol solution. Includes measuring ingredients PVA powder and deionized water. Mixing in a beaker on a stirrer. Heating on a hot plate with thermometer. Stirring for 30-60 minutes. Cooling to room temperature. Displaying final PVA solution ready for electrospinning. Labels for each step with technical terms
