Hello all,
I'm making cellulose aerogel from pineapple fibers. I mix fibers and PVA in water to form gel. But in the end, the obtain aerogels were not unique form. The fibers were at the bottom of aerogel and the white soft solid (I guess PVA) was on the top. How can I mix these two ingredients well?
I agree with @Noridali S. Normakhamatov. You must make sure the colloidal suspension is stable before you freeze dry it. In addition, you may also control the concentration of PVA to get stable dispersion.
Dear Nga Hoang Do Nguyen , what are you planning to do with the aerogel, what properties must have it? You have at least two option: you should modify your cellulose before apply for aerogel or you should use dispersing agents (Dispersants) for your mixture.
