Recent projects

Graphene multifunctional fibersultra-large graphene oxide sheet

We introduced the concept of one-step continuous large-scale fabrication of fully oriented graphene fibers, which is crucial to realizing production of graphene-based multifunctional 3D structures. We also addressed key fundamental issues regarding the formation of liquid crystalline (LC) dispersions of graphene oxide (GO) and their processability via a wet-spinning process.

We developed a solid understanding in the required criteria to correlate processability with LC behaviour, aspect ratio (ultra large GO sheets), dispersion concentration, and rheological behaviour to provide a viable universal platform to process different LC GO dispersions which is of both technological and fundamental interest in graphene field.

The new knowledge gained through rheological investigations provides a sound explanation as to why continuous spinning of binder-free and fully ordered graphene fibers and yarns is enabled by the LC behaviour at practical conditions. Advanced Functional Materials 2013, DOI: 10.1002/adfm.201300765.

Organic solvent-based graphene oxide liquid crystals

SEM image of the cross section of fully ordered graphene fiber

The highly promised applications of graphene-based liquid crystals were hindered mainly because of the practical limitations induced by water as the only medium in which graphene oxide liquid crystal was prepared. We introduced the discovery of solvophobic soft self-assembly of LC GO in a wide range of organic solvents, many of which were not known to afford solvophobic self-assembly prior to our discovery.

This discovery provides practical solutions to the processability of a wide range of materials that require organic solvents because of solubility issues and/or water sensitivity(i.e. metal oxides, polymers and nanomaterials) which is of both technological and fundamental interest for different applications.

We developed a solid understanding in the required criteria and mechanisms through which the solvophobic self-assembly provides a facile route towards next generation of self-assembled layer-by-layer multifunctional 3D graphene based architectures. ACS nano 2013, 7 , 3981-3990.
