Abstract
Carbon quantum dots (CQDs) are a special subset of carbon nanoparticles whose average dimensions are about 10 nanometers. Their unique properties include low toxicity, chemical inertness, excellent biocompatibility, and tunable luminescence behavior by surface modification. There are many sources in nature for the synthesis of CQDs, each of which has different effects on the properties of these particles. To synthesize CQDs, many methods have been introduced so far, including laser ablation, microwave radiation, hydrothermal reaction, electrochemical oxidation, reflux method and ultrasonication. Due to the small particle size of CQDs, they have strong tunable fluorescent properties. Applications of these particles have been examined in various fields such as photocatalysis, ions sensor, biological imaging, heavy metal detection, adsorption treatment, supercapacitor, membrane fabrication and water pollution treatment. Research works about CQDs in polymeric materials, especially composite materials reinforced with these nanoparticles, have been of interest in recent years. This is due to unique properties such as renewability, stability, high mechanical properties, and low weight and comparatively low cost of these particles. This review article is aimed to discuss the physical, chemical and stability properties of CQDs, raw materials and methods used in their synthesis, as well as their potential applications in various fields, especially in the rubber industry. Furthermore, in this article, we discuss recent progress regarding the use of CQDs in rubber products and their effects on the improvement of mechanical and dynamic properties.
