Special Issue Information
Dear Colleagues,
Nowadays, polyurethanes (PUs) are considered to be the most versatile and rapidly emerging class of polymers that are able to meet specific needs of our society. In the era of “plastics”, there is a continuously increasing demand for the manufacture of such polymers with various properties. Using the chemical reaction between isocyanates and polyols, PUs in different forms, including linear and crosslinked ones, can be synthesized. The wide variety of both the isocyanate and the polyol components, as well as the variation of the reaction conditions (e.g., the molar ratio of the reactants, catalyst, temperature, etc.) allows us to tailor the mechanical, chemical and even the biological properties for a particular PU system. In addition, the properties of PUs for a specific application can be further improved through the incorporation of various polymer segments and/or activatable bonds in the backbone, and/or by introducing specific pendant groups/segments onto the main polymer chain. The term “functional” in the manner we use herein represents not only the chemical modification (i.e., functionalization) possibilities, but also covers one or more functional properties operating based on different mechanisms. Self-healing assisted by shape memory properties is an excellent example of the combination of two functions working on different principles. Such “functional” PUs have attained considerable interest because of their manifold and unprecedented application possibilities.
The aim of this Special Issue of Polymers, entitled “Functional Polyurethanes II”, which is the continuation of the previous Special Issue “Functional Polyurethanes”, is to cover the most recent progress in the field of polyurethane “functionalization”. This Special Issue will also consider the novel design, synthesis and characterization of functional monomers/polymers including theoretical calculations, too, as well as the applications of functional PUs (e.g., coatings, nanocomposites, elastomers, ionomers, waterborne PUs, tissue engineering, shape memory, self-healing effects). Both research and review papers are welcome.

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.
