Three-dimensional carbon structures

Three-dimensional carbon structures

BACKGROUND 

Although carbon nanomaterials have been of high-interest in many fields of research and industry including energy capture, sensor development, mechanical reinforcement and biomedical applications, there are major shortcomings in the assembly of carbon nanomaterials into higher order structures. Two- and three-dimensional structures are required for many desirable applications of these applications. Present methods for 2D assemblies include challenges with regards to scalability, substrate suitability, mechanical stability, and/or biocompatibility. Even fewer few strategies exist for fabrication of three-dimensional structures (> 1mm in all dimensions).

DESCRIPTION 
Dr. Balaji Sitharaman has developed an easily scalable spray coating fabrication process for in situ chemical crosslinking of carbon nanomaterials to develop more robust, flexible, and biocompatible coatings/films. Furthermore, the process has been adapted to provide a layer-on-layer deposition of nanomaterials into three-dimensional structures. The nanomaterial films have shown significantly greater mechanical properties, good electrical conductivity, and cytocompatibility. The 3D structures are greater than 1mm in all dimensions and are about 60% porous. This work enables the fabrication of more robust carbon nanotube and graphene coatings by a facile, scalable, and flexible method.
ADVANTAGES 

The fabrication method is easy, cheap, rapid and scalable, allowing for large scale production of macroscopic all-carbon device. A potentially enabling technology for all-carbon nanomaterial 3D printing.
