Three active cellulose-based papers coated with chitosan (P–CH), chitosan–TiO2 nanocomposite (P–CH–TiO2) and chitosan–Ag/TiO2 nanocomposite (P–CH–Ag/TiO2), respectively, were subjected to real-time ageing for 6 months at 25 °C and 45% re humidity and characterized from a physical–chemical–antimicrobial perspective in relation to plain paper (P). Scanning electron microscopy pictures indicate a smooth...
A new carbon nanofibrous mat with necklace-like structures have been prepared by carbonization of cellulose/carbon black (CB) nanofibers through electrospinning of cellulose acetate/CB blend solution followed by deacetylation. The effect of carbon black on the thermal stability of the precursor and morphology of the CNFs were investigated using thermogravimetric analysis, field emission scanning electron...
The influence of enzymatic treatment on the thermal stability of cellulose nanofibrils (CNFs) was investigated. The unbleached bagasse pulp was treated with different dosages of xylanase, and samples were taken at different grinding stages. The produced CNF were characterized by Malvern Zetasizer, TEM, ATR-FTIR and XRD, and the thermal stability of the CNF was evaluated using TGA. The mechanism of...
