Hi, do you know any references about controlling porosity in silica sol-gel films by controlling AGING OF SOLUTION?

My results, based on FTIR measurements, are that films dip-coated from aged sols (1 week) show less porosity than films deposited from fresh sols, however I cannot provide a precise reason for that.

Thanks

ste
