Cellulose Nanofibers from Regenerated Cellulose fibers of Cigarette Butts and Application in Pickering Emulsion

Cellulose nanofibers (CNF) have been applied in various applications due to the abundant raw materials and excellent mechanical thermal properties. In this work, CNF from Cigarette butts (CNF-CB) was used as emulsion stabilized for oil water emulsion. prepared regenerated cellulose fibers that were produced by deacetylation of waste using autoclave then hydrolysis chemical treatment sulfuric acid. The FTIR spectra CNF-CB showed chemically convert waste, indicating removal acetyl group. TEM micrographs nanocellulose with diameters 8-32.30 nm. XRD analysis shows is a II allomorph crystallinity index about 88.04%. Thermogravimetric high char residue compared fibers. addition concentration 0.5% into oil-in-water (O/W) better stability than commercial surfactant. conclusion, approach offers promising strategy upcycling cigarette produce nanocellulose, which could be applications.
