Superamphiphobic coatings are the new advance approach of the coating which combines the advantages of above two coatings and act as oil and water repellent at the same time. Due to this combined advantage it can act as self cleaning coating, Antifingerprint coating, Anticorrosive coating, Anti-smudge coating at the same time and helps to improve the durability and service life of the substrate on which this coating is applied. The creation of this coating is based on the principle of chemical composition and surface topography. The surface can be make superamphiphobic by various methods like sol-gel coating, electrospinning in case of fiber, plasma etching in case of plastic substrate etc. Note de contenu : - INTRODUCTION : What do you mean by superamphiphobicity ?

VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : The surface topographies of different latex films, varnishes, and white paint films were investigated with an atomic force microscope. Four different latexes, consisting of homogeneous and composite particles as well as mixtures of different particles, were studied. The atomic force microscope proved to be an appropriate tool to reveal the surface structure of the films under ambient conditions. One result was that the gloss of the paint film is strictly correlated to the surface roughness of the corresponding pure latex film. With the exception of one example, the study revealed that solvents needed to prepare a varnish tend to reduce the surface roughness.

Surfaces (Physique)Index. décimale : 667.9 Revêtements et enduits Résumé : In this work, epoxy/2pack coatings containing polyaniline (PANI) in combination with Ag and ZnO nanoparticles have been synthesized. The nanoparticles were incorporated with bisphenol-A diglycidyl ether epoxy resin and polyamino-amide. The mechanical properties of the fabricated coatings, such as the pendulum hardness, scratch resistance, and impact strength, were studied. The composition of the fabricated coatings was confirmed by attenuated total reflectance infrared spectroscopy measurements. The thermal degradation and indentations were characterized through the use of differential scanning calorimetry and nano-indentation techniques, respectively. The surface morphology of the fabricated coatings was characterized using field-emission scanning electron microscopy. The synergistic effects of the Ag and ZnO nanoparticles on the corrosion resistance of the coatings after different exposure periods in 3.5% NaCl solutions were determined by electrochemical impedance spectroscopy. All the results were consistent with one another and confirmed that the addition of Ag and ZnO nanoparticles improved the mechanical properties of the coatings. This effect also led to a notable increase in the corrosion resistance of the PANI coatings. Note de contenu : - ATR-IR measurement

Surfaces (Physique)Index. décimale : 667.9 Revêtements et enduits Résumé : In this work, the changes in surface roughness and thickness of particles have been investigated after coating with polymers that result in hydrophobicity after a given time period. The study fundamentally investigates the evolution of these surface properties from the instant the particles are coated. Six chemical agents have been used on near-spherical glass beads and the changes in surface profiles monitored. Surface roughness was quantified using the power spectral density method and the surface thickness of the coatings was determined by a new technique which involved calculating the change in the representative radius of asperity. Results showed that the coating process altered the surface roughness and thickness of particles irrespective of chemicals used. The time-dependency of the coating process is illustrated and it was observed that fluctuations in both surface roughness and thickness lessened after a time period of 30 min. Depending on the chemical agent used, either an overall roughening or softening was recorded at 60 min and the values of surface thickness showed increases between 71 and 256 nm. By analyzing the evolution of surface roughness and thickness at the particle level following coating, this study demonstrated the intricate link between surface properties and chemistry in inducing functional properties on particles.
