Abstract
The incorporation of nanoparticles into cellulose materials to form nanocomposite is an interesting way of improving the functions and applications of cellulose. The properties associated with the nanoparticles contribute immensely to the overall behavior of the nanocomposites, which determine their applications. Cellulose-Ag-ZnO nanocomposites has been prepared using litchi peel extract and characterized by UV–visible and FTIR spectroscopic techniques, powdered X-ray diffraction (XRD) and transmission electron microscopy (TEM) analysis. The characterization techniques revealed the structure of the nanocomposites, which is composed of cellulose, Ag and ZnO, and the nanoparticles were agglomerated within the matrices of the cellulosic material. An ecotoxicological assessment of the nanocomposites was carried out using onion bulb plant to scientifically ascertain the benign nature of the biosynthesized materials. The results showed that exposure of the plant to increased concentration of the nanomaterials resulted in toxicity, which indicated that the nanocomposites are slightly toxic to the onions plant.
