a FTIR spectra of sawdust with and without fusion with IL with varying sawdust:IL ratios. b 13C CP/MAS NMR spectra of sawdust before and after IL treatment with sawdust:IL weight ratios from 1:0.5 to 1:3. The NMR spectrum of sawdust treated with IL (1:3 weight ratio) in a micro extruder is also included. Arrows above and below the spectra indicate the characteristic peaks of cellulose I and II, where the main changes took place
