Naturally nanostructured materials

Cellulose is the most abundant biopolymer on earth, featuring a hierarchical arrangement. The cellulose fibers can be broken down into building blocks of various dimensions. Low-dimensional building blocks enable significant tunability towards desirable optical, fluidic, ionic, mechanical, and thermal properties that far surpass traditional use of cellulose.

As a unique framework for sustainable nanomaterial, cellulose features hierarchically aligned structure from meters tall to ångstrom scale, offering immense opportunities with diverse length scale.

The high temperature synthesis (up to 3300 K) enabled by joule heating of carbon-based substrate opens a new paradigm of nanomaterials. Many new and exciting scientific discoveries on the correlations between high temperature synthesis-structure-properties await.


For example, the industry process often occurs at above 1300 K, but current methods of heat recovery in this temperature region has been limited. To efficiently convert heat to electricity a high operating temperature is desirable to ensure a high Carnot efficiency. The thermally-reduced solution-processed graphene oxide at 3300 K is shown to be a highly efficient and reliable thermometric material up to 3000 K. Thermal conductivity, electrical conductivity and Seebeck coefficient up to 3000 K were evaluated.
