DOI: 10.1007/s10570-018-1899-8
Abstract: Cellulose nanofiber/chitin nanofiber (CCN) suspensions can be converted into uniform composite hydrogels under acidic condition, because the chitin nanofiber and cellulose nanofiber have C6 carboxylate groups on their surfaces, which form hydrogen bonds. However, the electrostatic repulsion caused… read more here.
