Synthesis of Fullerenes by Electric Arc Discharge and Their Applications in Pyrotechnic and Lubricants
Abstract
Carbon has been one of the chief elements of the earth's civilization. It forms stronger bonds than any other materials in different forms. Several carbon-based nanomaterials have been developed in the past three decades through various synthesis processes. Their unique morphology and multifaceted properties have enabled them to be used in multidisciplinary fields. Carbon nanomaterials possesses outstanding mechanical, electrical, thermal, optical and chemical properties that make them ideal materials for tribological applications, with them exhibiting sustainable mechanical performance and efficiency. This article presents the results of experiments on the synthesis of fullerenes by electric arc discharge and their applications in pyrotechnic and lubricants. The results analysis obtained investigated of the methods Raman spectroscopy, scanning electron microscope and transmission electron microscope. Morphological studies using SEM and TEM images showed that the sizes of fullerene nanoparticles vary from 50 nm to 1 μm. The Raman spectrum shows the presence of peaks corresponding to fullerene. Obtained samples used lubricants and other tribological pyrotechnic. Based on the obtained results, it was determined that the longest detonation process of 11 seconds was observed when using a pyrotechnic composition of fullerene soot (15%), aluminum (10%) and potassium oxide (65%).
