These results suggest that the WG and amorphous cellulose components were intimately mixed with strong intermolecular interactions possibly through hydrogen-bonding.
It is interesting to note that these tanı maximum values of cellulose/WG systems are also lower than the value of the cellulose-only system produced at a higher temperature (150◦C). For cellulose/WG = 90/10 sample, the Tg was not distinct at all from both E’ and tan ı curves, indicating a pronounced motional restriction for WG and cellulose polymer chains and even chemical crosslinking between the two components under ECAP conditions.
