Hi...
I am making chitosan gel films for my further research. for that purpose I am solubilising chitosan (biopolymer) in acetic acid. Chitosan not dissoved 100% in acetic acid so next I am going for vaccume filtration to remove undissoved particles.But after filtration I found air bubbles in viscous gel. So can any one suggest me good and possible method or idea to remove air bubbles from chitosan gel.
Than you
