C., Islamic Azad University, Tehran, Iran Journal Article 2025 12 30 In this research work, carbon quantum dot nanoparticles derived from sugarcane bagasse were used in place of rubber industry aromatic oil and a portion of carbon black in five unique samples of the NR/BR elastomer mixture. The purpose of this research was to analyze the various mechanical, thermal, and rheological properties of the obtained mixtures. Comprehensive tests, including HR-TEM (High-Resolution Transmission Electron Microscopy), FESEM (Field Emission Scanning Electron Microscopy), DLS (Dynamic Light Scattering), and FTIR (Fourier Transform Infrared Spectroscopy), were employed to elucidate the properties of carbon quantum dots. In the following, elongation, tensile strength, abrasion resistance, rheometry, and Thermogravimetric analysis (TGA) tests were utilized to evaluate the mechanical, rheological, and thermal properties of the elastomeric mixtures. According to the collected results, among the synthesized samples, sample N3 had the most outstanding thermal, rheological, and mechanical properties. Overall, it is predicted that the interaction of carbon quantum dots with NR/BR elastomer can lead to reduced environmental risks and increased mechanical properties in the rubber industry.
