i made several thin or thick films by using dip coating . The upper part of these films are homogeneous , but the lower part of these films are being evaporated after being annealing at 800 degree Celsius . so i am using resin to cover this lower part while i am testing photoelectrochemical test of these films .
So how can i get i good film so that i dont need to add resin to the lower part of these films ?
N.B. air dried of film was done about four and half hour after dip coating .
Have you every check the effect of speed and viscosity of your solvent on the morphology of films? If you are using low viscous solvent, you should very careful of dip out speed. High speed may disturb your film quality.
Hey Mr Morteza ,
Thanks for your response .
The solution is very highly viscous .
Hello Swagotom
You could once try by properly finishing the surface. I mean to say by surface texturing by sand paper.
I believe that you might find some useful information for Lawrence Livermore Laboratory, Dave Milam would be the author.
