were investigated using synchrotron X-ray microdiffraction. The degradation of the up to
2100 year old fibres was found to depend on the climatic conditions at the place of storage.
The size and the lattice parameters of the cellulose nanocrystals (microfibrils) in the fibres
change upon degradation; these parameters are shown to be strongly correlated, leading to
a microscopic description of the degradation process in terms of molecular disorder. Artificial …
