Direct Growth of Substrate-Adhered Graphene on Flexible Polymer Substrates for Soft Electronics

This article describes a novel method of growing graphene directly on a flexible substrate at low temperatures using plasma-enhanced chemical vapor deposition with a solid aromatic hydrocarbon source, 1,2,3,4-tetraphenylnaphthalene (TPN), which acts as the feedstock for graphene growth. TPN is embedded with copper ions that are reduced under the growth conditions to copper nanoparticles that catalyze the graphene growth and then evaporate to...
