Special Issue Information
Dear Colleagues,
The mechanical properties of solid polymers have been known for many years. Over the past twenty years, in this domain, there has been tremendous progress in fundamental polymer physics. This progress has been made possible by the development of new experiments regarding the dynamics of polymers in confinement, dynamics of fluorescent probes, in situ dielectric, or NMR spectroscopy. Studies of the ultimate properties and the corresponding microscopic mechanisms have benefited from progress in electron microscopy, ultra-small-angle scattering techniques, and in acoustic detection for studying, e.g., cavitation event statistics. New techniques that combine atomic force microscopy and dielectric or Raman spectroscopy are being developed to probe polymer properties on a local scale. Theoretical developments have led to new mesoscopic models that can describe the plastic properties of glassy polymers in a quantitative way and consistently with the basic requirements of statistical physics. Molecular dynamics simulations have brought new insights regarding damaging and cavitation, and also regarding the plasticity of glassy polymers. Progress in chemistry and rheology/processing methods allow more and more to prepare materials with the desired morphologies and dispersion to enhance the properties.
This Special Issue of the International Journal of Molecular Sciences will highlight these new trends and achievements.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
