| Abstract Scope |
The synthesis and characterization of a fully bio-based thermoplastic polyurethane (PU) reinforced with graphene nanoparticles, derived entirely from rubber seed oil (RSO) was conducted. The polyol was prepared via epoxidation and oxirane ring-opening, while the polyisocyanate was synthesized using the Çaylı and Küsefoğlu method. Graphene nanoparticles were incorporated to enhance thermal and mechanical performance. A petroleum-based PU was also prepared for comparison. FTIR confirmed urethane linkage formation. Thermal analysis showed an onset degradation temperature of 292 °C for the graphene-reinforced bio-based PU (vs. 285 °C without graphene and 305 °C for petroleum-based PU). Tg increased slightly to −12 °C, and tensile strength improved to 10.6 MPa with 245% elongation at break. The nanocomposite demonstrated excellent processability and strength, making it suitable for flexible packaging, electronics, coatings, and footwear. This study highlights the potential of RSO and graphene in developing sustainable, high-performance polyurethane materials. |
