Electrical and Microstructural Characterisation of GNP Hybrid Conductive Inks
摘要
The development of high performance conductive inks for flexible and printed electronics requires a detailed understanding of how filler composition, thermal processing, and microstructural evolution influence electrical behaviour. Hybrid systems, combining graphene nanoplatelet (GNP) with metallic fillers such as silver (Ag) and zinc (Z), have shown particular promise due to the synergistic formation of conductive networks. However, the precise interplay between GNPs loading, curing temperature, and the resulting conductive network remains a critical factor in determining ink performance.
