and differential thermogram curves of the raw materials(WNP and p-WNP) and the products (Film and f-Film) are almostentirely the same. The onset decomposition temperature (Tonset)and the temperature of maximum weight loss rate (Tmax) of allsamples are about 340◦C and 380◦C, respectively. That means theregenerated cellulose-based films exhibited high thermal stability,which was as good as that of native cellulose materials
