Development and characterization of carbon-based conductive pastes with high mechanical integrity under bending stress for room-temperature printable electronics.

ABSTRACT: Room temperature processing of flexible electronics has become of great interest, as it allows for simpler and cheaper methodologies for high throughput manufacturing of printed electronics. This study focuses on the development and characterization of carbon-based conductive pastes made from a combination of graphite (G) and carbon black (CB), in a polymethyl methacrylate (PMMA) polymer matrix. Raw materials were characterized by Raman Spectroscopy, FTIR, SEM and TEM, showing the structural properties, morphologies and particles size which influenced the characteristics of the pastes. By varying the ratios of G/CB (1 to 4), carbon filler content (11.6-20%), and polymer content (1.5-7%), 48 different formulations were fabricated and further analyzed to determine their electrical conductivi
