“…Based on the results of SEM, particle size affects the roughness of the surface morphology, the smaller the size of the particles formed, the higher the hydrophobicity and the lower the surface energy. This decreased surface energy is due to the small interaction between water and the glass surface which causes high interactions between water and air, so that the water will tend to maintain its spherical shape, as a result the contact angle between the water and the glass surface formed will be even greater [13]. Based on the size of the particles formed, the best hydrophobic properties are found in the variation of the composition of SiMn 50%:50% with a particle size of 50.05 nm.…”

Many researches on the synthesis of hydrophobic coatings have been carried out, but in use, the coating is easily scratched, easily damaged by contact with other objects and easy to corrode, thereby reducing the quality of the coating. This can hinder the application of hydrophobic coatings in industry and others. Therefore, it is necessary to develop a hydrophobic coating that is strong and durable and anti-corrosion so that it can improve the quality of a surface. For this reason, research is carried out by mixing a substrate that has anti-corrosion properties such as silica and is hard such as manganese in order to overcome the problems that occurred previously using the spin coating method. The precursor was made by adding 0.5 grams of polystyrene composition, with varying SiMn composition. The coating was carried out using the spin coating method and the calcination temperature was 60°C using an oven for 1 hour. The results of this study from the composition variation showed that the SiMn/PS nanocomposite layer was hydrophobic based on the contact angle test. The largest contact angle at 50%:50% composition.

“…Hydrophobic thin films sourced from Aloe vera are one of the efforts to produce coating materials for anti-pathogenic microorganisms by adding polystyrene polymers as a matrix (reinforcer) (Seifunnisha et al, 2021) . The hydrophobic coating has the characteristics of being effective in self-cleaning and having a contact angle of >90 • (Ratnawulan et al, 2020;Fauzi, 2019;Fauzi and Putri, 2020). Aloe vera leaves have a gel that can be prepared into flour/powder to have better physical properties and be more resistant to damage (Maan et al, 2021;Wang and Dai, 2016;Hendrawati, 2015).…”

The spread of pathogenic microorganisms on a large scale creates a health disaster for the world. Modifying the surface of the fabric so that it is antimicrobial pathogens with hydrophobic properties is one solution to inhibit the spread of microorganisms. Surface modification was carried out using Aloe vera powder as filler and polystyrene matrix with Aloe vera:PS composition variations of 1:5, 2:5, and 3:5 using the dip coating method and drying temperatures of 10◦C, 50◦C, and 90◦C. The characterization results that have been carried out with the best composition variations are 3:5 and 50◦C with a layered morphology using Scanning Electron Microscopy (SEM), resulting in a surface particle size of 21.243 nm, large contact angle/WCA using a Canon D350 camera with a size of 150.23◦, Fourier Transmission Infrared Analysis (FTIR) with the dominant functional group in the vibration band 2629 cm−1 indicates the presence of a long hydroxyl chain, the vibration band 1500 cm−1 with C-H stretching of the aromatic ring is caused by the characteristics of the polystyrene polymer and the wave number is 1700 cm−1 with stretching C=O which shows the characteristics of the carbonyl group in the Aloe vera sample is a flavonoid compound. The resistance of Aloe vera/PS solution to Klebsiella pneumonia resulted in a 20.18 mm diameter barrier showing strong resistance against bacteria and X-Ray Diffraction analysis showed that the AV powder was amorphous. Thus, the AV/PS 3:5 composition with a calcination temperature of 50◦C represents the greatest variation in the synthesis and characterization of hydrophobic thin films for pathogenic antimicrobial organisms.

“…A large number of organic additives have been studied as hydrophobic agents are silan alcoses, surfactants, acrylics, polytetrafluoroethylene (PTFE), polyethan eterketon (PEEK), silanized diatomaceous earth (DE) or Polyuteran (PU) [4] [5]. The material is coated onto the surface of mortar cement with epoxy resin to obtain a superhydrophobic hydrophobikataupun surface.…”

Mortar cement resistance has serious economic implications in the form of maintenance costs and replacement of a structure. Therefore it is necessary to make cement mortar that is waterproof or hydrophobic. The purpose of this study was to look at the effect of the composition of hydrophobic agents on the large contact angle and strength of mortal cement. The hydrophobic agent used is Tetrahydrofuran (THF) with polyurethane (PU) with variations of 5:6molar, 1:10molar, 1:10.9 molar with total each variation being 11 molars. The control variables in this study are the amount of composition of otawa sand, aquades and silica sand 20-30 mesh which is 4:11:2 mold 5 cm x 5cm cement mortar cubes, long immersion with Ca(OH)2 10% for 7 days, temperature 60 °C and heating length 1 hour. The large angle of contact is measured using the caessyal drop method and the hardness value using the hardness vickers tool. The results showed that the higher the concentration of Polyuteran, the smaller the contact angle of mortar cement produced. The largest contact angle occurs at the concentration of THF variation: PU 6:5 mol. The optimum contact angle is 126° and the mortal seemen are hydrophobic.
