Abstract Scope |
The addition of binders such as cellulose is often required during ink design with exfoliated 2D nanoflakes to optimize printing rheology for applications such as flexible electronics. Despite this, cellulose acts as an electrical insulator that significantly disrupts inter-flake electrical transport. This necessitates removal often by extended thermal burnout. Previous reports have shown beneficial conductivity gains at temperatures short of burnout which have been attributed to the formation of conductive residue between the constituent flakes. In this talk, ethyl-cellulose and exfoliated graphene flakes are used as a model system for characterizing the role of heating environment on the temperature induced evolution of cellulose-embedded flake networks. This is quantified with respect to sample chemistry, morphology, and electrical transport. While complete thermal burnout is often employed for binder removal, this work aims at identifying less energy intensive processing conditions which may be suitable for more delicate substrates or exfoliated materials. |
