“…More recently, the ability of plasma polymers to retain chemical functionality has been exploited to fabricate non-fouling surfaces, [11][12][13] graft polymer brushes to surfaces, [14] and attach biomolecules to surfaces in order to improve biocompatibility and cell adhesion. [15] Indeed functionalized plasma polymers have found application in a wide variety of areas, including coatings on fibers, [16] improving interfacial adhesion in composite materials, [17] for cell attachment [18] and screening, [19] nanoparticle attachment, [20] biosensors, [21] and as membranes for fuel cells. [22] One class of plasma polymer which has been extensively used is those containing amine groups.…”

Amine containing plasma polymer films are of interest due to their ability to bind biomolecules either covalently or electrostatically. One issue with generating such plasma polymers is the need to generate sufficient amine density on the surface to enable binding, while simultaneously maintaining the chemical, physical stability of the surface in aqueous media. Here we investigate the relationship between plasma parameters, film stability for two commonly used monomers, allylamine AA, ethylenediamine EDA. Plasma polymer films from AA, EDA were produced at radio frequency RF powers between 2 and 20 W at a constant monomer flowrate. Deposition rate, ion flux, ion energy, plasma phase mass spectrometry were used to investigate the plasma-surface interactions. Film stability was assessed by comparing X-ray photoelectron spectroscopy XPS, atomic force microscopy AFM measurements before, after washing in phosphate buffered saline PBS. The results show that films generated from EDA plasmas are generally unstable in aqueous media, while films generated from AA plasmas exhibit higher stability, particularly those deposited at high RF power. The chemical, physical stability of the films is then related to the mechanisms of deposition, the energy density provided to the surface during film growth.

“…These surfaces have a number of practical applications in various areas such as cleaning coatings [31], biomédical [10], anti-icing [30,32,33], anti-fouling [34,35] and anticorrosion [32], anti-sticking surfaces [36], anti-contamination of glass surfaces such as windows in buildings and windshields in vehicles [37]. Several studies showed a good correlation between hydrophobicity, especially superhydrophobicity and icephobicity of surfaces [7,30,32,[38][39][40][41][42][43]. Hence, the fabrication of hydrophobic and superhydrophobic surfaces has much promise in anti-icing application.…”

Accumulated ice on exposed surfaces leads to operational difficulties and extensive maintenance for power transmission lines, antennas, aircraft, ships, and ground transportation vehicles.In the present study, the low pressure plasma polymerized Hexamethyldisiloxane (PP-HMDSO) film is deposited on aluminum surfaces to create a superhydrophobic coating with icephobic properties. Prior to the deposition of this low surface energy coating, aluminum surfaces were anodized or immersed in boiling water to make micro/nano structured surfaces.Plasma parameters were optimized in order to find the best optimum conditions for having high static contact angle and low contact angle hysteresis. Hence, the Grey-based Taguchi method was used as one of the Design of Experiment (DOE) techniques. The stability of coatings was studied under accelerated aging conditions such as UV degradation, immersion in distilled water and different pH solutions, and several icing/deicing cycles. It was observed that the PP-HMDSO coatings are quite stable against UV exposure and immersion in distilled water. However, the icephobicity of the PP-HMDSO coating deposited on the anodized aluminum decreased after fifteen icing/de-icing cycles.The stability of the developed coating was improved against several icing/de-icing cycles by increasing the deposition time of plasma polymerized coating from 15 to 25 minutes. The results showed that increasing the deposition time of plasma polymerization leads to decrease of the ice adhesion strength of coatings on anodized aluminum while it has no significant effect on the PP-HMDSO coating deposited on a water-treated aluminum surface. Finally, the superhydrophobic PP-HMDSO coating also provides anti-corrosion protection for the aluminum substrate.

“…Silicon containing precursors like tetramethylsilane (TMS), tetraethoxysilane (TEOS), and hexamethyldisiloxane (HMDSO) is used for surface modification in textile industries. Among these, HMDSO precursor is nontoxic and nonexplosive and has a high vapor pressure at room temperature than TEOS [35][36][37][38]. Due to the presence of methyl groups; Si, H, and C atoms; and oxygen bond on the HMDSO, it changes the surface of the fabric into hydrophobic [35][36][37][38][39].…”

In this work, we study the hydrophobic properties of silk fabrics by deposition of plasma-polymerized (pp) hexamethyldisiloxane (HMDSO) using low-pressure plasma-enhanced chemical vapor deposition. Recently, hydrophobic properties are under active research in textile industry. The effects of coating time and power on the HMDSO-coated silk fabrics are investigated. Water contact angle of pp-HMDSO-coated silk fabric surface is measured as a function of power and coating time. Fabric surface shows an enhancement in hydrophobicity after coating. Attenuated total reflectance-Fourier transform infrared spectroscopy reveals the surface chemistry, and scanning electron microscopy shows the surface morphology of the uncoated and HMDSO-coated fabrics, respectively. In the case of uncoated fabric, water droplet absorbs swiftly, whereas in the case of HMDSO-coated fabric, water droplet remains on the fabric surface with a maximum contact angle of 140[Formula: see text]. The HMDSO-deposited silk surface is found to be durable after detergent washing. Common stains such as ink, tea, milk, turmeric and orange juice are tested on the surface of both fabrics. In HMDSO-coated fabrics, all the stains are bedded like ball droplet. In order to study the self-cleaning property, the fabric is tilted to 45[Formula: see text] angle; stain droplets easily roll off from the fabric.
