Opis:
The aim of this communication is to explore a simple and efficient method for fabrication of superhydrophobic surface by candle smoke particles (CSPs). The properties of CSPs before and after the calcination process has been studied by SEM, TEM, TG-DSC, FT-IR and contact angle measurements. The results show that there is a complex mixture of elemental carbon and a variety of hydrocarbons in association with amorphous nanomaterial in CSPs, whose structure and composition leads to superhydrophobic properties. The wetting properties of CSPs can turn from superhydrophobic into superhydrophilic due to characteristic group changes by calcination process. Thus, it is a simple and efficient method to fabricate superhydrophobic or superhydrophilic surface by CSPs at low cost.

Opis:
The surface morphology, structure and hydrophobicity of low-and high-molecular weight poly(dimethylsiloxane) (PDMS) fluids physically adsorbed onto multi-walled carbon nanotubes (MWCNTs) at different weight percentages (5, 10, 20 and 40 wt.%), were studied employing X-ray diffraction (XRD), attenuated total reflectanceFouriertransforminfrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM) and measurements of contact angle with water. It was found that MWCNTs agglomerate forming voids between tubes of a broad range, while adsorption of the polymer from a hexane solution results in the expected wrapping of nanotubes withPDMS chains and, further, in filling voids, as represented by SEM data. ATR-FTIR was used to investigate the possible structural changes in the polymer nanocomposites. Based on the contact anglemeasurementsvia water drop shape analysis,MWCNTs/PDMS nanocomposites were characterizedas astable,superhydrophobic materials with the maximum contact angle (CA) equal to 152°at CPDMS=40wt.%.

Opis:
Digital processing of the optical image of a sessile droplet was used to study the influence of dodecanol vapors and condensate on the wettability of superhydrophobic coatings by water. Two types of coatings with very different morphologies were used to estimate the stability of the superhydrophobic state in the presence of dodecanol at different regimes of interaction of tested superhydrophobic coatings with dodecanol vapors, including preliminary condensation of dodecanol inside the substrate pores/grooves at different temperatures, a short-term contact of dodecanol vapor with the superhydrophobic coating with the preliminary deposited water droplets and, finally, a long-term contact between substrate with deposited water droplets and the vapor phase saturated with dodecanol vapor. The set of experimental data indicate only minor variations of water contact and roll-off angles for all regimes studied. Such wettability behavior evidences good persistence of superhydrophobic state in conditions of contact with long-chain alcohol vapors.
