Special Issue Information

Dear Colleagues,

We are pleased to announce a forthcoming Special Issue entitled “Sustainable Printed Electronics: From Materials to Applications”, which will feature selected submissions from the Sustainable Printed Electronics 2025 (SPE2025) conference, taking place from September 23–25, 2025, in Thessaloniki, Greece. The conference brings together experts from academia, research, and industry to discuss the latest developments in sustainable materials, technologies, and applications in the field of printed electronics (PEs).

This Special Issue aims to highlight innovative research addressing sustainability challenges in the development and life cycle of printed electronic devices. We welcome both original research papers and reviews that contribute to advancing environmentally conscious solutions, including biodegradable materials, recyclable components, cutting-edge manufacturing of PEs, and their applications. Topics such as circular economy strategies and safe and sustainable-by-design (SSbD) methodologies are also encouraged.

Potential topics of interest for this Special Issue include the following:

  • Bio-based and biodegradable materials for printed electronics;
  • Safe and sustainable-by-design ink formulations;
  • Advanced materials: metal nanoparticles, carbon dots, conductive nanocomposites;
  • Circular economy approaches for printed electronics;
  • Reuse, recycling, and de-bonding techniques;
  • Applications in smart packaging, wearables, sensors, and energy devices;
  • Scalable, low-cost, and energy-efficient manufacturing processes.

Submissions from both conference attendees and external contributors are welcome.

We look forward to your valuable contributions to this exciting and timely Special Issue.

The synthesis of two series of poly(lactic acid) (PLA)-based polymer nanocomposites (PNCs) filled with small amounts (0.5 and 1%) of Ag and Cu nanoparticles (NPs) was performed. Moreover, two methods for the PNC synthesis were performed, namely, ‘conventional mixing techniques’ and ‘in situ ring opening polymerization (ROP)’. The latter method was employed for the first time; moreover, it was found to be more effective in achieving very good NP dispersion in the polymer matrix as well as the formation of interfacial polymer–NP interactions. The in situ ROP for PLA/Cu was not productive due to the oxidation of Cu NPs being faster than the initiation of ROP. The presence of NPs resulted in suppression of the glass transition temperature, Tg (23–60 °C), with the effects being by far stronger in the case of ROP-based PNCs, e.g., exhibiting Tg decrease by tens of K. Due to that surprising result, the ROP-based PLA/Ag PNCs exhibited elevated ionic conductivity phenomena (at room temperature). This can be exploited in specific applications, e.g., mimicking the facilitated small molecules permeation. The effects of NPs on crystallinity (2–39%) were found opposite between the two series. Crystallinity was facilitated/suppressed in the mixing/ROP -based PNCs, respectively. The local and segmental molecular mobility map was constructed for these systems for the first time. Combining the overall data, a concluding scenario was employed, that involved the densification of the polymer close to the NPs’ surface and the free volume increase away from them. Finally, an exceptional effect was observed in PLA + 0.5% Ag (ROP). The crystallization involvement resulted in a severe suppression of Tg (−25 °C). Full article
