Superhydrophobic behavior of lauryl methacrylate copolymers on the cotton fabric surface

Abstract

The authors propose to use glycidyl methacrylate and lauryl methacrylate copolymers to provide the cotton fabric surface with superhydrophobic properties. The modification was carried out by immersion of cotton fabric in solutions of copolymers in methylethylketone and following heat treatment at 140°C. Stability of the superhydrophobic state of polymer coatings is studied during long-term contact with droplets of water and aqueous acidic, alkaline and salt solutions under saturated vapor conditions. Under the conditions of high humidity and absence of contact with the external environment, a low drop evaporation rate is ensured, which allows to trace the long-term change of the contact angle of the sessile drop. The mechanism of stability of superhydrophobic properties is discussed. Polymer coatings that are based on the glycidyl methacrylate and lauryl methacrylate block copolymer provide better stability of superhydrophobic properties compared with the random copolymer. It is shown that modification of the cotton fabric surface by glycidyl methacrylate and lauryl methacrylate copolymers does not affect its vapor permeability.

[8][9][10][11] By grasping the mechanism that governs liquid-solid interactions, solid surfaces can be designed and fabricated to meet demands in industrial applications, such as slippery superhydrophobic surfaces for self-cleaning, 12,13 anti-icing, [14][15][16] drag reduction 13 and enhanced condensation, 17 sticky superhydrophobic surfaces for liquid capturing, [18][19][20] superhydrophobic fabric for water and dirt resistance, 21 superhydrophilic surfaces for boiling 22 and water collection 23 and other surfaces. 24 Adhesion force measurement is an effective way to quantify the interactions between liquid and solid surfaces.…”

“…Both papers give bright examples of an extremely wide area of fundamental and applied research in the branches of nanotechnology targeted on the fabrication of protective superhydrophobic coatings. The lauryl methacrylate and glycidyl methacrylate copolymers grafted by Bryuzgin et al 4 onto cotton fabric allow achievement of the superhydrophobic state of fabric surface with a long-term chemical stability in acidic and alkaline media. In the paper by Ganne et al, 5 the significant anti-icing potential was demonstrated for the protective coating, fabricated using laser texturing and fluorooxysilane chemisorption on the surface of stainless steel meshes.…”
