C (Tmax =326 C) is lower than that of pure cellulose (Tmax = 345 C). This result
suggested that the strong intra- and inter-molecular hydrogen
bonds of cellulose were partially broken by IL during the solution
process, which is coincident with the result of the X-ray diffraction.
The maximum decomposition temperatures of the composite films
(Tmax = 331–335 C) are slightly lower than that of pure cellulose,
but higher than that of starch (Tmax = 309 C), lignin and RC, showing
relatively high thermal stability because of the enhancement of
inter-molec
