Special Issue Information
Dear Colleagues,
Recently, polyurethanes (PUs) have attracted a great deal of research interest due to their segmented block copolymeric character, which endows them with a wide ranging versatility in terms of their physical properties and biocompatibility. The production of polyurethanes (PUs) with specific functional properties is possible through the appropriate selection of the type and concentrations of reactive components (polyol and isocyanate), and building on advances in PU chemistry research. These combinations enable a material with specific mechanical parameters as well as different levels of resistivity and biocompatibility, depending on the needs of the final application, to be obtained. Consequently, PU materials can be tailored to the desired and most specific applications. According to the survey conducted by Covestro in 2019, the global demand for PUs had reached an estimated 18.4 million tons, and is forecast to increase to 22.5 million tons by 2024. This means that, in 2021, the PU market reached a value of more than USD 80 billion.
Polyurethane-based materials may be available in different forms: flexible or rigid foams and uses including one-component and two-component adhesives, sealants, elastomers, polyurethane coatings, and medical and biomedical devices. Owing to their biocompatibility, possible biodegradability (PUs based on renewable resources), excellent mechanical strength, and adjustable physical forms, PUs deployed to serve a wide range of applications, especially in the field of biomedicine, have garnered significant research attention in recent years. The synthesis of biocompatible polyurethane is of immense interest in the biomedical and pharmaceutical fields; however, the properties of these materials must be fine-tuned in order to prevent negative effects on the surrounding tissue. Initially used for long-term implants, now a new class of bioresorbable polyurethane materials has been developed.
This Special Issue is fully aligned with the objectives of the sustainable development of new classes of polymers, particularly the adherent scientific and industrial priorities, through the development of innovative PU materials for high-value applications. This means that the development of new, safer, and more sustainable alternatives in many applications enables the development of innovative products that seek to fulfil the needs of contemporary society.

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.
