“…Indeed, the surface roughness continues to excess with increasing filler percentage so that in sample N5MOH, the surface roughness is quite clear. As indicated in all of other relevant research, filler concentration, which passes through the critical level, causes a nonuniform distribution of fillers and changes the surface morphology [14]. By observing the sample surface, we can see that there is no cracking, which indicates the optimal quality of sample fabrication.…”

“…The soft segment is produced by polyether or polyester polyol, whereas the hard segment is produced by isocyanate and chain extenders [13]. Due to the existence of hard segments, PU exhibits advantageous characteristics such as a high glass transition temperature and a high melting temperature [14]. Nevertheless, PU does have a few significant limitations, particularly in high-temperature working situations, including inadequate tensile strength, poor thermal stability, low thermal and electrical conductivity, and insufficient anticorrosive qualities.…”

Polyurethane (PU) is one of the most well-known polymer coatings because of its favorable characteristics, which include its low density, nontoxicity, nonflammability, longevity, adhesion, simple manufacture, flexibility, and hardness. However, PU does come with several major drawbacks, among which are poor mechanical properties as well as low thermal and chemical stability, particularly in the high-temperature mode, where becomes gets flammable and loses adhesion ability. The limitations have inspired researchers to develop a PU composite to improve the weaknesses by adding different reinforcements. Magnesium hydroxide, having the ability to be produced with exceptional properties such as flammability, has consistently attracted the interest of researchers. Additionally, silica nanoparticles with high strength and hardness are one of the excellent reinforcements of polymers these days. The hydrophobic, physical, and mechanical properties of pure polyurethane and the composite type (nano, micro, and hybrid) fabricated with the drop casting method were examined in this study. 3-Aminopropyl triethoxysilane was applied as a functionalized agent. To confirm that hydrophilic particles turned into hydrophobic, FTIR analysis was carried out. The impact of size, percentage, and kind of fillers on different properties of PU/Mg(OH)2-SiO2 was then investigated using different analyses including spectroscopy and mechanical and hydrophobicity tests. The resultant observations demonstrated that different surface topographies can be obtained from the presence of particles of different sizes and percentages on the hybrid composite’s surface. Surface roughness allowed for exceptionally high water contact angles, which confirmed the hybrid polymer coatings’ superhydrophobic properties. According to the particle size and content, the distribution of fillers in the matrix also improved the mechanical properties.
