Special Issue Information

Dear Colleagues,

Coatings offer surface functionality which enables the use of substrate materials that otherwise would be unsuitable for service. While the field of coatings has been researched heavily and technologies have reached a certain maturity, new challenges are constantly emerging. The need to relentlessly and sustainably improve performance at reduced costs is driving new innovations in coatings. In recent years, the drive has been to achieve multi-functional coatings to satisfy the ever-increasing demand of the industry and survive the global competition. New coating technologies, responsive to the changes in the environment and multifunctional, are constantly emerging. Among the numerous new coating technologies, those which show most promise include:

  • self-healing coatings
  • antifouling coatings
  • antimicrobial coatings
  • super hydrophobic/oleophobic coatings
  • biologically active coatings
  • easy/self-cleaning coatings
  • photoactive coatings
  • thermochromic coatings
  • electrochromic coatings
  • sensory coatings

Although the list of coating technologies and applications is growing, the challenge remains for these innovative technologies to be economically viable and sustainable. This Special Issue will focus on the new challenges in coating technologies, including economic viability and sustainability during raw material procurement, production, service, and end of life.

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. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Zinc (Zn) and zinc–nickel (Zn–Ni) electrodeposition has been widely used in many industries, such as automotive and aerospace, for corrosion protection of steel components owing to their excellent corrosion resistance. Conventional zinc and zinc–nickel electrodeposition is performed in different types of aqueous baths (acid and alkaline). Such electrolytes suffer from certain drawbacks such as hydrogen gas evolution, low coulombic efficiencies, and environmental toxicity. Electrodeposition of Zn and Zn–Ni alloys from ionic liquids has gained significant attention in aerospace and automotive sectors owing to the different environments they provide for electrodeposition. This paper reviews the progress in deposition of zinc and zinc-nickel alloys in non-aqueous systems, especially ionic liquids. In addition, the challenges and technological developments associated with the Zn and Zn–Ni deposition on different substrates and the factors that need to be considered while electroplating at an industrial scale are discussed.
