Experimental study demonstrates enhanced mechanical and thermal stability in nanocellulose-reinforced natural rubber composites, highlighting their potential as sustainable biomaterials.
An environmentally sustainable approach utilizing xylanase enzyme hydrolysis was employed for the effective isolation of nanocellulose (NC) from Acalypha hispida leaves. The obtained NC was subsequently incorporated into deproteinized natural rubber (DPNR) latex to produce reinforced bio‐composites. Fourier Transform Infrared (FTIR) spectroscopy and morphological studies supported the strong interfacial bonding and homogeneous distribution of NC within the NR matrix. Introducing NC strengthened the structural integrity of NR composites, owing to the reinforcing effect of NC. Swelling behavior measurements demonstrated a reduction in solvent uptake, indicating increased crosslinking and restricted polymer chain mobility. Thermogravimetric analysis (TGA) revealed a significant increase in thermal resistance of the composites. The enhanced swelling resistance, mechanical strength, and thermal stability of these composites indicate their suitability for use as biomaterials.
