Dual functional jute fabric biocomposite with chitosan and phosphorylated nano-cellulose (antimicrobial and thermal stability).

In the present study, phosphorylated nanocellulose (P-NC) has been prepared from date palm sheath fibers by a solvent-free acid hydrolysis procedure. Eighteen different treatment procedures were employed for the composite treatment of jute fabric. Different fractions of phosphorylated nanocellulose (1-4%) and chitosan (0.5-2%) were used to examine the effects of treatment procedures on the resulting jute fabric composites. Weight uptake, phosphorus content and tensile properties of the treated jute fabrics have been reported. ATR-FTIR spectroscopy, X-ray diffractometer, transmission electron microscopy, environmental scanning electron microscopy, energy-dispersive X-ray spectroscopy and thermo-gravimetric analysis were used to gain insight into the mechanism of interaction between jute fabric, CS macromolecules, and P-NCs. In addition, the development of antimicrobial and thermal stability properties on jute fabric has been investigated.
