Editorial: Editors’ showcase 2023: polymers

Polymer science, a most colorful petal of the soft-matter flower, and certainly its economically most relevant subdiscipline, is at the core of the current challenges of humankind. Both the growing plastic pollution and climate change can be addressed by modern polymer materials being more sustainable and having wider functionality (Saalwaechter, 2022). It is thus a great pleasure for me to present our most recent Editor’s showcase of the section Polymers of Frontiers in Soft Matter, which features 7 articles that highlight the research scope and the dedication of the editors of our young journal to serve our society with innovative methods and developments, so as to address the pressing questions.

The development of new polymer materials is tightly linked to their in-depth characterization, allowing us to explore fundamental structure-dynamics-property correlations and thus to move forward in a targeted rather than trial-and-error way. In this vein, our current Showcase focuses on physical characterization techniques capable of revealing information that was not routinely accessible in the past. All contributions highlight how such enhanced understanding sheds new light on our ability to design better materials in the long run.

Successive Self-nucleation and Annealing (SSA) is a thermal fractionation technique that is performed by Differential Scanning Calorimetry (DSC). The combination of non-isothermal and isothermal steps applied during SSA achieves efficient molecular segregation during polymer crystallization. Such molecular segregation magnifies the effect of defects in polymer chain crystallization, thereby providing information on chain structure. The technique was created and implemented by Müller and co-workers in 1997, becoming a powerful resource for studying ethylene/α-olefin copolymers. The different variables to design the SSA protocol: fractionation window, fractionation time, scanning rate, sample mass, and the first self-nucleation temperature to be applied (Ts, ideal), have been previously reviewed, together with the different applications of SSA. SSA versatility, simplicity (when properly applied), and short times to produce results have allowed its use to study novel and more complex polymeric systems. This review article explores the most recent applications of SSA of the past decade. First, the principles of the technique are briefly explained, covering all the relevant variables. Next, we have selected different cases that show how SSA is employed in various novel fields, such as studying intermolecular interactions and topological effects in homopolymers; supernucleation and antinucleation effects in nanocomposites, including the pre-freezing phenomenon; crystallization modes in random copolymers; solid-solid transitions; miscibility, co-crystallization and composition in blends; evaluation of polymer synthesis variables; and the novel information that could be gained by using chip-based fast scanning calorimetry. Finally, we offer a perspective on SSA, a technique that has become a powerful method for studying the distribution of defects affecting crystallization in semi-crystalline polymers.
