| I am a graduate of the Department of Chemistry of the Aristotle University of Thessaloniki (2024) and I am currently pursuing my master’s degree at the same department, specialising in ‘Chemistry and Technology of Polymer and Nanocomposite Materials’. |
Abstract
| Amid intensifying environmental concerns, the pursuit of sustainable alternatives to conventional plastics is paramount. Polylactic acid (PLA) is a promising candidate due to its biodegradability, bio-based nature, compostability, and recyclability. This environmentally benign polyester is noted for thermal properties similar to fossil polymers and sustainable large-scale production. Within this context, Silver (Ag) nanoparticles offer excellent conductivity, stability, durability, and printability. Copper (Cu) nanoparticles are also prominent in research due to their antimicrobial properties, low cost, and enhance polymer mechanical, thermal, and barrier performance. However, PLA nanocomposites with these NPs, particularly for printed electronics (PE), are relatively unexplored. Developing innovative, low-cost processing methods for PE using PLA substrates with Ag/Cu NPs is an emerging research area. This research endeavors to synthesize PLA/Ag nanocomposites via in situ ROP/melt extrusion, and PLA/Cu via melt extrusion, using 0.5 and 1.0 wt% NPs concentrations. The resulting nanocomposites were characterized for structural, morphological, thermal, and mechanical properties. Silver ink adhesion was tested on PLA/PET substrates to explore printed electronics applications. Additionally, PLA cast film samples based on NPs were also produced. |
