Special Issue Information

Dear Colleagues,

Over the years, polymers have been widely studied and applied to numerous fields due to their versatile and adjustable chemical and physical properties. The use of synthetic polymers has especially seen significant growth and application in many sophisticated fields, such as biomedicine, sensors, electronics, energy storage, and convention devices.

This Special Issue aims to highlight recent progress in the manufacturing, characterization, and modification of polymeric materials with applications in the energy, biomedical, and electrical fields. It is our pleasure to invite you to submit your manuscript.

Potential topics include, but are not limited to, the following:

  • Polymer-based materials for energy storage (i.e., electrochemical capacitors and batteries) and green energy systems;
  • Bio-based and bio-sourced polymers;
  • Polymeric materials derived from natural/synthetic fibers and textiles;
  • Polymeric materials for health and biomedical applications;
  • Self-assembled polymers;
  • Polymers for electronic devices and packaging materials.

This study investigated the self-healing properties of PA6/COC blends, in particular, the impact of three compatibilizers on the rheological, microstructural, and thermomechanical properties. Dynamic rheological analysis revealed that ethylene glycidyl methacrylate (E-GMA) played a crucial role in reducing interfacial tension and promoting PA6 chain entanglement with COC domains. Mechanical tests showed that poly(ethylene)-graft-maleic anhydride (PE-g-MAH) and polyolefin elastomer-graft-maleic anhydride (POE-g-MAH) compatibilizers enhanced elongation at break, while E-GMA had a milder effect. A thermal healing process at 140 °C for 1 h was carried out on specimens broken in fracture toughness tests, performed under quasi-static and impact conditions, and healing efficiency (HE) was evaluated as the ratio of critical stress intensity factors of healed and virgin samples. All the compatibilizers increased HE, especially E-GMA, achieving 28.5% and 68% in quasi-static and impact conditions, respectively. SEM images of specimens tested in quasi-static conditions showed that all the compatibilizers induced PA6 plasticization and crack corrugation, thus hindering COC flow in the crack zone. Conversely, under impact conditions, E-GMA led to the formation of brittle fractures with planar surfaces, promoting COC flow and thus higher HE values. This study demonstrated that compatibilizers, loading mode, and fracture surface morphologies strongly influenced self-healing performance. Full article
