Special Issue Information
Dear Colleagues,
Living organisms heal wounds and damage by generating new tissue to replace damaged organs and restore original function. Although synthetic materials are far from possessing this hyper-efficient repair mechanism, the concept of self-healing is gaining momentum in the scientific literature to describe a plethora of man-made materials including metals, ceramics and polymers, used in emerging technological fields.
In this context, self-healing (SH) materials are synthetic substances capable of repairing damage without external input of virgin/repair material. The SH mechanism is activated either autonomously or by external triggering (heat or radiation) using "resources" built into the material formulation as healing agents or reversible chemical bonds. Undoubtedly, polymer science is the field experiencing the fastest growth of self-healing applications, with the publication rate of scientific papers increasing exponentially.
Pushed by the increasing concern about disposal or and recycling of industrial and municipal waste, the intrinsic ability of self-healing polymers to be easily recycled, reworked and repaired has stimulated the research of new materials and applications in the field of coatings, composites and biomaterials, just to name a few.
Nonetheless, significant efforts are still needed to increase the technology readiness levels (TRL) of self-healing materials and application and to establish unambiguous definitions and evaluation criteria.
This Special Issue aims to promote the research and application of self-healing polymers and contribute to the development of reusable, recyclable and more durable engineering materials, with a reduced environmental footprint and which are suitable for promoting the transition towards a circular economy business model.

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. Molecules 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.
