Special Issue Information

Dear Colleagues,

Materials sciences have a major role in meeting the current global challenges such as environmental stewardship; the production, storage, and conversion of energy; and cost-effective transportation, leading the research towards designing advanced polymer materials that consider both their shelf- and end-of-life. Through the concept “function through structural design”, the development of easy and new production methods is crucial for preparing innovative polymer materials solutions and thus ensures a sustainable future. Consequently, in recent years, the polymer materials community has put a great deal of effort into designing innovative polymer materials that are engineered to be multifunctional or task-specific, presenting enhancement in properties such as ionic conductivity, chemical and thermal stability, mechanical performance, fire retardancy, barrier properties, self-healing ability, and shape memory behavior. This can be effectively achieved by altering the interphase behavior of these polymer systems, both via chemical modification or incorporating additives/fillers such as block copolymers, ionomers, organic–inorganic hybrid materials, or inorganic-rich nano-objects. Among these, the application of (poly)ionic liquids, eutectic solvents, and eutectic molecular liquids have presented many new opportunities within the last decade, since small amounts of these compounds can impart dramatic interphase modifications to polymer materials due the production of vast physical interphase bonding, including the formation of ionic bonding. Especially considering their unique set of physico-chemical properties as well as their multitude of chemical structures, they represent a promising new path to design and creation of new multifunctional and task-specific polymeric materials.

In this study, we set out to modify poly(lactic acid) (PLA) by incorporating epoxidized ionic liquids (ILs) that were specifically designed with imidazolium-NTf2 moieties. First, we synthesized di-, tri- and tetra-epoxidized ILs, which were incorporated into a PLA matrix at 3, 5, and 10 wt% through a melt extrusion process. We investigated the relationship between the structure and properties of the resulting materials in terms of thermal, mechanical, rheological, and surface properties. The results showed the potential of ILs to impact these properties. Notably, the tri- and tetra-epoxidized ILs enhanced the thermal stability of the PLA matrix as well as the crystallinity while reducing the glass transition temperature and melting point, which is promising for reactive extrusion processing. Overall, this research opens new routes for using reactive ILs to improve the processing and properties of PLA polymers. Full article
