| Abstract Scope |
Additive Manufacturing has increased our ability to fabricate complex shapes and multi-material structures. Epoxy is excellent as the base for structural composite materials and carbon nanotubes (CNTs) add several functionalities such as electrical conductivity to a composite. However, 3D printing of epoxy-CNT composites is not fully developed. Here, conductive structures were fabricated by 3D direct-write printing of epoxy-CNT composite inks and their electrical and mechanical properties were characterized. In this process, 3D printable composite inks were synthesized by mixing epoxy, CNT, and nanoclay – a rheology modifier – using magnetic stirring, ultrasonication, and centrifugal mixing. Rheology measurements show an increase in storage modulus with incorporation of both nanoclay and CNT. Electrical conductivity of ~ 10-3 S/cm was measured for a composite with 1 wt% CNT. Furthermore, the effects of concentration of CNTs on the electrical and mechanical properties of the printed and cured structures were characterized.
