Abstract
This research develops advanced nanocomposites from natural rubber (NR) and synthetic polymers to enhance mechanical, thermal, and electrical properties while promoting sustainability. Liquid natural rubber (LNR) emulsions (10,000 and 50,000 g/mol) were prepared using SDS; lower molecular weight LNR showed better stability with less emulsifier use. LDPE/LNR blends (100/0 to 40/60) achieved optimal stress–strain performance at 60/40 composition, with DSC confirming blend homogeneity. HDPE/LNR composites with organo-modified montmorillonite (OMMT) (3–15% LNR, 3–5% OMMT) showed improved tensile, impact, and thermal stability, with exfoliated or mixed structures confirmed by XRD and TEM. Nylon-6/LNR blends with 2–10% clay improved mechanical properties at 85/15 ratio. PC/LNR/OMMT nanocomposites (2–10% OMMT) displayed higher thermal degradation temperatures. NR/PS matrices with 11.91–36.25% polypyrrole nanoparticles achieved conductivities of 1.77×10⁻⁸–1.07×10⁻⁴ S/cm, alongside increased tensile strength and modulus. Overall, incorporating nanomaterials effectively tailors NR-based materials for diverse industrial applications aligned with sustainability objectives.
