Compressive Mechanical Properties of Carbon Nanotube Sponges: Experiments and Modeling

Article Preview

Abstract:

Carbon nanotube (CNT) sponges are three-dimensional frameworks of interconnected CNTs with great potentials in composite and environmental applications. CNT sponges with lateral sizes of centimeters have been prepared through chemical vapor deposition (CVD), and their compressive mechanical properties are studied. To gain deep insight on the microstructure and how CNTs are connected within the sponges, we propose a simple theoretical model to understand the arrangement as well as the interconnection of CNTs. The mechanical properties of CNT sponges can be well explained and predicted using this model.
