Article Synopsis
- Self-healing polymers present a new solution to wear and tear in polymer products, addressing damage from mechanical stress and environmental factors.
- A series of high-strength copolymers were developed using acrylamide, acrylic acid, and various metal complexes (Co(II), Ni(II), Cu(II)), and their properties were extensively analyzed through multiple physicochemical techniques.
- Nickel-based metallopolymers showed the highest self-healing efficiency (up to 83%) while retaining impressive tensile strength, demonstrating the potential to enhance mechanical properties through different metal ions.
In our study, we investigated the accelerated aging process of PLA under 253.7 nm UV-C irradiation with the use of the GPC, NMR, FTIR, and DSC methods and formal kinetic analysis. The results of GPC and DSC indicated a significant degree of destructive changes in the PLA macromolecules, while spectroscopic methods NMR and FTIR showed maintenance of the PLA main structural elements even after a long time of UV exposure.

This paper reports on a successful attempt to obtain self-healing copolymers films of acrylic acid, acrylamide and a new metal-containing complex of cobalt acrylate with a 4'-phenyl-2,2':6',2″-terpyridine ligand. Samples of the formed copolymer films were characterized by ATR/FT-IR and UV-vis spectroscopy, elemental analysis, DSC and TGA, SAXS, WAXS and XRD studies.
