Abstract

In this study, we coated the surface of glass slides with nanoprotrusion, nanoparticles, and nanofilm structures by one-step plasma deposition of three vinyl monomers. Three functional vinyl monomers with symmetrical polarity sites were used: methyl methacrylate (MMA), trifluoro methylmethacrylate (TFMA), and trimethylsilyl methyl methacrylate (TSMA). The TSMA/MMA (80/20, mol-%) nanoprotrusion-coated surface of slide glass was superhydrophobic, with a 153° contact angle. We also evaluated the transmittance (%) of the slide glass with nanoprotrusions in the infrared (IR) (940 nm), ultraviolet (365 nm) and visible light (380–700 nm) regions. The obtained nanoprotrusion structure surface of slide glass created by plasma deposition transmits more than 90% of visible light.

Highlights

Materials with superhydrophobic properties are in extremely high demand because they have various potential applications, which include anti-corrosion coatings, microfluidic devices, oil/water separation, anti-icing coatings, nanoparticle assembly, liquidrepellent textiles, printing techniques, optical devices, highly sensitive sensors and batteries [1,2,3,4,5,6,7,8]
Of the plasma-coated polymer-coated slide glass three times according to the molar tance (%) of the plasma-coated polymer-coated slide glass three times according toratio the of trifluoro methylmethacrylate (TFMA)/methyl methacrylate (MMA)
In order to create superhydrophobic coatings, vinyl polymer coatings were formed on the surface of glass slides through a plasma process

Summary

Introduction

Materials with superhydrophobic properties are in extremely high demand because they have various potential applications, which include anti-corrosion coatings, microfluidic devices, oil/water separation, anti-icing coatings, nanoparticle assembly, liquidrepellent textiles, printing techniques, optical devices, highly sensitive sensors and batteries [1,2,3,4,5,6,7,8]. In many of these applications, having a layer of air trapped inside a rough surface can reduce liquid penetration (oil/water separation, anti-fogging), ion penetration (anti-corrosion, water desalination, batteries), or heat transfer (anti-icing), while surface roughness can improve the inherent properties of a material (electrical, optical, and catalytic properties). The results indicate that vinyl monomers are and polymerized on the surface during the cold plasma process
