Abstract

Different spectrum can be used in characterization and upsetting the performance of our daily
application. Fourier transform infrared (FTIR) spectroscopy is used to make structural analysis for materials.
The need to have low cost, portable, and suitable size FTIR to be used onsite application is in need. A novel
microelectromechanical system (MEMS)-based FTIR spectrometer device is made to solve this problem.
Epoxy coating is used frequently to protect steel pipelines from environmental conditions against corrosion.
Its drawback is that it performs with low resistance for crack initiation and propagation. In addition, the
absorption of ultraviolet radiation (UV) deteriorates its properties. Which reduces the lifetime of the coating.
Having direct and indirect economic losses. The usage of alumina nanoparticles with a small amount of
weight percentage of 0.25 wt. % can enhance mechanical properties. The key factor is having a good
distribution of nanoparticles inside the epoxy-resin matrix. The investigation of the mechanical properties,
bulk properties as in flexural strength, and surface properties as in erosion resistance and hardness are studied.
Furthermore, the effect of 48 h UVA absorption on the performance of these properties with different
alumina nanoparticles wt. % is investigated. For the bulk properties, the addition of alumina nanoparticles
having an insignificant effect, while in surface properties, the effect of UV reduces with the increase in
particle wt. %. The MEMS-FTIR has good agreement with mechanical properties. Indicating the distribution
of particles inside the system. Supported by environmental scanning electron microscope (ESEM) images.
This shows that MEMS-FTIR is a useful instrument used in non-destructive, low cost, onsite material
analysis.
