Zhou et al. [7] found that PMMA grafted onto the surface of sisal fibers enhanced the intermolecular interaction between fibers and PP matrix, hence improved the tensile strength of the composites.

From these figures, it was observed that the existence of Al peak after plasma treatment is due to the cathode material, where the argon ions accelerated toward the cathode liberate Al atoms by sputtering from its surface and therefore deposit on the metal substrate surface.
The change of contact angles for the irradiated and non irradiated metals is due to the Al atoms filling the space on the metal‘s surface.

Sofyan et al. (2017) and Sinha et al. (2018) used FTO with an active area of
1 cm2 [11,12].
This spectrum aligns with that reported by Safie et al (2015) and Ismail et al (2021)[21,22].

Zhengyuan Li et al. observed that the Y-rich nano-oxide could reduce the oxidation rate in Fe-Cr-Al alloys and enhance the high-temperature stability because of the pinning effect of nano-oxide [11].

Fe2O3, Fe-Cr spinel, and Fe-Al-rich oxides formed on the Fe-18Cr-nano Al2O3 ODS after exposure to humified atmospheres.
The Fe-Al-rich oxides may cause to retard the mass gain relating to oxidation when exposed for a long time.

Actually the similar hydrophilic and thermo-sensitive micro-spheres based on organotrialkoxysilanes have been reported by Jung et al.[11] These studies were focused to explore the physicochemical properties and structure information of the micro-spheres.
