Green Synthesis and Investigation of the Functional Behavior of Carbon Quantum Dots in Elastomeric Compounds Based on (BR/SBR)

In this study, carbon quantum dot nanomaterials obtained from sugarcane bagasse have been used in the liquid phase in five distinct formulations as a substitute for aromatic oil and part of carbon black in BR/SBR elastomeric compounds. This research aimed to study the rheological, mechanical, and thermal properties of the compounds developed with carbon quantum dots. DLS (Dynamic Light Scattering), HR-TEM (High-Resolution Transmission Electron Microscope), FESEM (Field Emission Scanning Electron Microscope), and FTIR (Fourier Transform Infrared Spectroscopy) were used to characterize the carbon quantum dot. Also, tensile strength, wear, rheometry, and Thermogravimetric analysis (TGA) tests were used to check elastomeric compounds' mechanical, rheological, and thermal properties. Based on the obtained data, sample N3 showed the best rheological, mechanical, and thermal properties among the manufactured samples. Overall, these nanomaterials are expected to be an appropriate substitute for the aromatic oil used in the rubber industry.
