Chitin nanopaper from mushroom extract: natural composite of nanofibers and glucan from a single biobased source
An isolation method with mild mechanical agitation and no acidic extraction step from a mushroom substrate resulted in chitin nanofibers (ChNFs) with large shares of retained glucans (50−65%). The subsequent chitin nanopapers exhibited exceptionally high tensile strengths of >200 MPa and modul...

| Summary: | An isolation method with mild mechanical agitation
and no acidic extraction step from a mushroom substrate resulted in
chitin nanofibers (ChNFs) with large shares of retained glucans
(50−65%). The subsequent chitin nanopapers exhibited exceptionally high tensile strengths of >200 MPa and moduli of ca. 7 GPa,
which were largely attributed to the preserved glucans in the
mixture, imparting a composite nature to the nanopapers. The
isolation method for ChNFs is notably different from the
conventional process with crustacean chitin sources that do not
incorporate glucans and where an acidic extraction step for the
removal of minerals must always be included. |
