FTIR results suggest that Zn 2+ ions promote Zn···O3H interactions, which in-turn weaken the intrinsic O3H···O5 hydrogen bonds that are responsible for strengthening the cellulose chains.

The measurement results using FTIR and EDX are shown in Figure 5. Measurements were taken on both the sample surface and a cross section using FTIR. The results of FTIR measurement showed that, for ...
