Carbon Black (CB) is widely used as a filler in rubber materials. CB has been obtained from the thermal cracking process of petroleum hydrocarbons. With the depletion of petroleum reserves, it is necessary to substitute carbon black using natural materials such as coconut shells. This research studied the thermal and microstructure properties of Coconut Shell Nanoparticles (CSNP). CSNP was synthesized by the ball mill method and coprecipitation method. Synthesis of Coconut Shell (CS) by coprecipitation method with various solvents affects the thermal properties and microstructure of the resulting carbon black. Morphological results showed that most of the carbon pores were formed, and the dominant elements in the sample were carbon and oxygen. The appearance of the absorption band, which is characteristic of CB in CS samples, was confirmed from the FTIR results. In addition, from XRD analysis, the particle size of CSNP1, CSNP2, CSNP3 samples was (33.2, 52.92, and 54.98) nm with an amorphous structure. The endothermic peak is associated with phase reduction and decomposition reactions. The thermal stability of nanoparticle coconut shells is better than coconut shells. © 2006-2023 Asian Research Publishing Network (ARPN). All rights reserved.
