Hi All,
Im trying to increase the film porosity by adding PEG to the sol while preparation.
In this method, i first add the surfactant to ethanol & then add TTIP & acid to the same & then spin coat the sol. annealing of the same was done.
When i checked for the response, it reduced wrt without surfactant.
I expected the porosity to increase & hence the response.
Does the method of preparing the sol with surfactant need to be modified?

Hope to get inputs from you.
Thanks in advance!!
