The associated supplementary files consist of data visualisations and tabular representations that provide evidence and validate the debates and outcomes, as explained in the next section. Figure 1S to 3S display FT-IR spectra of cellulose extracted from reed (RC), cellulose aerogel derived from reed (RCA), and cellulose aerogel coated with MTMS (RCA_MTMS). Figures 4S to 6S display the differential thermal analysis (DTA) results of three different samples: isolated cellulose (RC), reed-based cellulose aerogel (RCA), and MTMS-coated cellulose aerogel (RCA_MTMS). Figures 7S to 8S display the BET results of two types of cellulose aerogel: reed-based cellulose aerogel (RCA) and MTMS-coated cellulose aerogel (RCA_MTMS). Figures 9S to 10S depict the water contact angle (WCA) of the cut surface and external surface of RCA (recycled concrete aggregate). Tables 1S to 4S display the impacts of parameters such as sulfidity, active alkali, L:W ratio, and boiling time on the isolation of cellulose fibres, respectively.
