Exploring the feasibility of Babul-cellulose nanofiber nanocomposites as a sustainable alternative: Synthesis and properties analysis

Abstract

Biodegradable polymers are a promising alternative to traditional, non-degradable polymers in various applications. Research into the use of primarily monosaccharides and natural tree gums has shown great potential in technology. Experiments on various gums, including Acacia nilotica (Babul), have revealed their excellent mechanical properties. In this study, biodegradable and water-soluble nanocomposites were synthesized using Acacia nilotica reinforced with different volume proportions (5 %, 10 %, 15 %, and 20 %) of cellulose nanofibers. The widely-used hydrothermal method was employed to obtain cellulose nanofibers (CNF), which were then used to create bubble gum. Sorbitol was used as a plasticizer during liquid metallurgy processes to form films. The properties of these films, including tensile strength, modulus of elasticity, contact angle, and moisture content were analyzed. The effect of reinforcement on the matrix was also analyzed using a scanning electron microscope (SEM). The low hydrophilicity and improved mechanical strength of these nanocomposites offer new possibilities for use in pharmaceutical and bio-edible coatings.
