Hello,
leaving cellulose ( above , on the surface , in water ) for 20 hours would cause , bring any change ? will they stick together ?or not
Thank you
It depends the type of Cellulose. Nanocellulose will most probably agglomerate. However pure cellulose will not react with water in any how.
I think there won't be any agglomerations while cellulose is in (on) the water, neither in the case of cellulose fibers nor nanocellulose and water molecules simply diffuse into the cellulose bulk or between nanocelluse fibers or whiskers and form hydrogen bonds with them. But now if you dry this cellulose again, only nanocellulose will stick together due to the formation of irreversible hydrogen bonds.
Thank you very much Andile , Catherine
Caterine : "But now if you dry this cellulose again, only nanocellulose will stick together due to the formation of irreversible hydrogen bonds"
do you have a paper about that? because I am interested in cellulose after the drying
Thank you very Much
Dear Zouhir,
The effects of drying on the fibre structure of cellulose are usually referred to as hornification.The term is also used to describe the irreversible agglomeration which can occur during drying of aqueous suspensions of nanocellulose.
I hope the attached paper will help.
Dear Zouhir,
Keep celulose in water is usefull sometimes to give the effect of sweeling into the fibers to easly further process like hydrolysis. It´s very common used on celulose microcrystalline previous submit it to H2SO4 in some papers.
Best regards
