Cellulose is a versatile biopolymer increasingly applied in medicine and industry due to its biodegradability biocompatibility, along with the renewability large availability of source materials. However, finding simple, eco-friendly, effective methods modify cellulose provide it new functionalities remains challenge. This work presents new, inexpensive, eco-friendly method chemically microcrystalline (MCC) by submerged cold plasma treatment an aqueous suspension MCC containing different oxidizing agents, such as hydrogen peroxide (H2O2), sodium hypochlorite (NaClO), or periodate (NaIO4). Fourier-transform Infrared (FTIR) X-ray photoelectron spectroscopy (XPS) showed that intensified effect H2O2, NaClO, NaIO4, plasma-assisted NaClO yielding highest oxidation level. XPS indicated oxidations also resulted degrees chemical degradation MCC, further supported thermogravimetric analysis (TGA) results. diffraction (XRD) data revealed agents on crystalline amorphous regions MCC. Scanning electron microscopy (SEM) images combined led fragmentation varying defibrillation into nanofibers.
