FTIR, TGA/DSC, BET, and WCA analyses of materials, as well as effects of parameters on isolating cellulose fibers from reed

This study focused on fabricating a cellulose aerogel for oil spill cleanup, using common reed (Phragmites australis) as the cellulose source. The process involved isolating cellulose from reed via traditional Kraft pulping, considering the effects of key factors on the isolated cellulose content. After a two-stage HP bleaching sequence, the highest cellulose content achieved was 27.2%, with 80% ISO brightness and 1% ash content under mild Kraft pulping conditions of 30% sulfidity, 20% active alkali, sustained cooking at 165°C for 3 hours, and a liquor-to-reed ratio of 8:1. Subsequently, reed-based cellulose aerogel was fabricated via a freeze-drying method using an eco-friendly NaOH/PEG aqueous solvent system, which was then modified with methyltrimethoxysilane (MTMS). The resulting aerogel exhibited remarkable characteristics, including a low density of 0.04 g/cm³, high porosity of 96%, high hydrophobicity with a water contact angle (WAC) of 141°, and a superior crude oil adsorption c..., Conducted experimental chemistry at a scaled-up level, collected data, tested physical and chemical properties, and applied the results to crude oil absorption., , # FTIR, TGA/DSC, BET, and WCA analyses of materials, as well as effects of parameters on isolating cellulose fibers from reed

### Description of the data and file structure:

The associated supplementary files consist of data visualizations and tabular representations that provide evidence to validate the debates and outcomes, as explained in the following section. Figures 1S to 3S display the FTIR spectra of cellulose extracted from reed (RC), reed-derived cellulose aerogel (RCA), and MTMS-coated cellulose aerogel (RCA_MTMS). Figures 4S to 6S present the thermogravimetric analysis (TGA)/differential scanning calorimetry (DSC): isolated cellulose (RC), reed-based cellulose aerogel (RCA), and MTMS-coated cellulose aerogel (RCA_MTMS). Figures 7S to 8S show the BET results for 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 angles (WCA) for both the cut and external surfaces of RCA ...
