Special Issue Information

Dear Colleagues,

After the discovery of the superhydrophobic abilities of lotus leaf due to its specific surface geometry in micro- and nanoscale, many academic and industrial efforts have been made to mimic lotus leaf in synthesized and treated coatings and surfaces. Due to the large range of potential applications, the subject of superhydrophobicity and related properties (e.g., self-cleaning, anti-fouling, icephobicity) have found special enthusiasm in both fundamental research and industrial applications. The spectrum of superhydrophobic surfaces and coatings grows every year, and its progress is expected to continue for decades in the future. Although much effort has been made in the subject, there are common problems limiting their application in industry, including high prices, low fabrication efficiency and durability. Therefore, for this Special Issue we welcome papers on all kinds of polymer coatings and surfaces. Different techniques for the treatment and fabrication of surfaces and coatings (chemical treatments and modifications, etching, electrospinning, sol–gel, laser treatments, etc.) can be applied to achieve materials with superhydrophobic properties. Fabricated materials can also exhibit combined properties (in addition to hydro- and superhydrophobicity, also self-cleaning properties, icephobicity, anti-fouling, etc.)

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Robust membrane materials with high efficiency have attracted extensive attention in oil/water separation. In this work, carbon particles via candle combustion were firstly adsorbed on the surface of stainless steel meshes (SSMs), which formed a thin hydrophobic coating, and a rough structure was then constructed through chemical vapor deposition and high temperature calcination, with the resultant SSM surface wrapped with uniform silica coating possessing the characteristic of superoleophobicity underwater. Scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray powder diffraction (XRD) were used to characterize the modified SSMs. The prepared SSMs were superhydrophilic in air, and they had superoleophobicity underwater (157.4°). The separation efficiency of five oil/water mixtures was above 98.8%, and the separation flux was 46,300 L·m−2·h−1. After it was immersed in 1 mol/L NaOH, 1 mol/L HCl and 3.5 wt% NaCl for 24 h, respectively, the efficiency was still above 97.3%. Further immersion in the solution of dopamine and octadecylamine resulted in the transformation of superhydrophililc/superoleophobicity-underwater SSMs to superhydrophobic SSMs, and the resultant SSMs with reverse surface wettability was also used for the oil/water separation with good separation efficiency and separation flux.
