Hi Dear Leila,

I suggest the following alternatives:

1-Let the solvent of the polymer solution partially evaporate. This will thicken your polymer solution.

2-Subject the polymer solution to multiple cooling and warming cycles while stirring. This helps increase the number of hydrogen bonds in the polymer solution.

3-Expose the polymer solution to UV radiation. Using medium-range UV radiation may enhance the formation of hydrogen bonds in the polymer solution.

Let me know if it was helpful.

Hello, You could accelerate aging by storing the solution at a higher temperature with controlled humidity, which enhances cross-linking and hydrogen bond formation.

Best regards.
