My goal is to uniformally functionalize cellulose membrane. However, I am aware
that cellulose is composed of crystaline and amorphous regions; each has
different chemical reactivity. Is there any pre-treatment method to convert
crystaline region into amorphous one? I try to use solvents (DMSO, acetone, DMF,
acetonitrile) with different wetting capacity, but I'm not sure if this is
sufficient. If possible, I do not want to totally dissolve the cellulose membrane.
