Introduction

The increasing demand for efficient and sustainable lubricants has led to the development of nano lubricants, which have shown promising results in various industrial applications. One of the key challenges in the development of nano lubricants is the improvement of their physical properties, such as viscosity and performance. In this study, we investigate the effect of adding Tetraethyl Orthosilicate (Teos) as a material coating in nano particles Fe3O4 for nano lubricant application. The addition of Teos is expected to improve the physical properties of the nano lubricant, making it a more efficient and sustainable option for various industrial applications.

Materials and Methods

The research process begins by mixing Fe3O4 powder into distilled water, ethanol, and ammonia. The addition of Teos with volume variations (0.9 ml; 1.2 ml; 1.5 ml; and 2.5 ml) is then carried out to observe the effect of the coating material on the physical properties of the nano particles. The resulting sample is then dried and undergoes a series of characterizations to observe the physical properties of nanoparticles, both not coated or coated with the Teos as silica.

Characterization of Nano Particles

The analysis begins with a true density and microstructure examination using a microscope electron transmission (TEM). The experimental results showed that nanoparticles that had been coated with the Silica Teos underwent significant changes in the physical aspect, with a density value and particle size that was larger compared to nanoparticles before being coated in silica. This reflects that the coating process has succeeded in changing the morphology and structure of the particle.

Furthermore, testing using Fourier Transform Infrared Spectroscopy (FTIR) shows a shift in absorption on the Silica FE3O4 spectrum. The emergence of the Si-O-C and Si-O-si-si-si-si-si-si-si-S-Si-si-Si-S-Si-S-Si-Si bands in the FTIR spectrum indicates that Teos functions not only as a coating, but also contributes to changes in the chemical properties of the nanoparticles.

Analysis of Physical Properties of Nano Lubricant

The analysis of the physical properties of the nano lubricant is carried out to assess the effect of the addition of Teos on the viscosity and performance of the lubricant. The results of this analysis revealed that with a change in density value, the addition of silica has a significant impact on the physical properties of the lubricant nano produced. When silica is added, the viscosity and performance of the lubricant can be increased, which can support efficiency in the application of the performance.

Discussion

The results of this study show the importance of the use of Teos in improving the performance of Nanoparticles FE3O4 as Nano Lubricant. With the characteristics that have been improved, the final product of this study is expected to provide innovative solutions to challenges in the lubrication industry, as well as opening up the way for further research on the application of nano material in various fields of engineering and industry. In addition, the superiority of Nano Lubricant, which includes resistance to good temperature and coating, makes it an interesting choice to replace traditional lubricants.

Conclusion

In conclusion, the addition of Teos as a material coating in nano particles Fe3O4 has shown significant improvements in the physical properties of the nano lubricant. The results of this study demonstrate the potential of Teos in improving the performance of nano lubricants, making them a more efficient and sustainable option for various industrial applications.
