“…Considering the insolubility of natural cellulose, the effective utilization of cellulose is mainly through chemical modi cation to form cellulose derivatives (Mettu et al 2021) (e.g., carboxymethyl cellulose (CMC), methylcellulose (MC), hydroxypropyl methylcellulose (HPMC), cellulose acetate (CA), and hydroxyethyl cellulose (HEC) (Cho et al 2021)), or through micro/nano processing to form microcrystalline cellulose (MCC) or nanocellulose ). Among these, nanocellulose is gaining tremendous research attention due to its superior properties such as renewability, biodegradability, biocompatibility, high aspect ratio, high speci c surface area, easy availability, high mechanical strength, and good modi ability (Sun et al 2021).…”

In this study, the oxidized cellulose nano brils from pineapple peel (PP-TOCNF) were prepared by TEMPOmediated oxidation followed by ball milling. The in uence of oxidation degree on the structure and properties of PP-TOCNF were investigated, including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), atomic force microscope (AFM), X-ray photoelectron spectroscopy (XPS) and thermogravimetry (TG), as well as the potential application in aerogels. The results suggested that TEMPO oxidation facilitated the dispersion of PP-TOCNF due to the strong electrostatic repulsion between -COO − groups. Regulating oxidation degree by varying NaClO concentration could effectively adjust the -COO − content (0.167 ~ 0.550 mmol/g), zeta potential (-18 ~ -34 mV) and rheological properties. The obtained PP-TOCNF showed a long brillar structure, whose average diameter and CrI values gradually decreased with the increase of oxidation degree. The PP-TOCNF-based aerogels exhibited a light weight, good porosity, water absorption, and mechanical properties, which also can be easily adjusted by oxidation degree of PP-TOCNF. Furthermore, TEMPO oxidation improved the stability and shape recovery ability of aerogels in water.
