Different from the regenerated materials,
all of the composite films become quite amorphous after dissolved
and blended in IL, probably due to the strong dissolving effect of
AmimCl and the formation of inter-molecular hydrogen bond
among cellulose, starch and lignin. The three biopolymers can be
dispersed molecularly in AmimCl, and the molecular chains are
aggregated in rapid coagulation process, which hinders the crystallization
of cellulose and starch.
