Special Issue Information
Dear Colleagues,
This Special Issue is dedicated to Heterogeneous Materials Based on Polymers. At this point, it is important to remark that it is the long-range elasticity, high strength, and high viscosity which define the macromolecular nature of organic polymers, depending on the inter-molecular forces’ intensity. These properties emerge as a direct consequence of the size and constitution of the covalent structures of the macromolecules, determined by the interchain interactions at the distance of a primary bond (thermosetting polymers), or by secondary interactions between sufficiently large polymer chains able to induce strong interchain forces that endow the matter with enough structural integrity to be useful and handled (thermoplastic polymers), which—conversely to thermosetting polymers—can soften and flow under temperature and shear fields. The combination of these polymers with other substances (fillers, reinforcements, fibers, other polymers, et cetera) with the aim of obtaining lower costs in a shorter time frame, rather than simply correcting an undesired property is still a growing and promising research direction, and is being applied to obtain novel outstanding materials. In any case, it is the role played by the contact regions between the components (the interphase) which governs and defines the ultimate properties of the material. The inter-phase is defined as that dynamic and finite spatial region between the borders of each couple of different phases which are microscopically in contact. Transport phenomena occur at the nanoscale level through the atoms (or small groups of atoms) placed there, and are responsible for the momentum, mass, and energy balances between both phases. On this basis, the study of the interphases with the aim of controlling the properties of any given multi-component system has been established, giving rise to the concept of tailor-made materials. In any case, from a heterogeneous polymer-based materials perspective following either top-down or bottom-up approaches, the strategy of designing materials rather than designing with materials emerges.

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. Materials 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 2600 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.
