Mechanochemically aminated multilayer graphene for carbon/polypropylene graft polymers and nanocomposites

Graphene-multilayer graphene nanocomposites as highly efficient thermal interface materials.

We found that the optimized mixture of graphene and multilayer graphene, produced by the high-yield inexpensive liquid-phase-exfoliation technique, can lead to an extremely strong enhancement of the cross-plane thermal conductivity K of the composite. The "laser flash" measurements revealed a record-high enhancement of K by 2300% in the graphene-based polymer at the filler loading fraction f = ...

Tunable electrical and thermal transport in ice-templated multilayer graphene nanocomposites through freezing rate control.

We demonstrate tunable electrical and thermal conductivities through freezing rate control in solution-based nanocomposites. For a prototypical suspension of 1 vol % multilayer graphene suspended in hexadecane, the solid-liquid electrical conductivity contrast ratio can be tuned from 1 to 4.5 orders of magnitude for freezing rates between 10(2) and 10(-3) °C/min. We hypothesize that this dramat...

Graphene-Based Polymer Nanocomposites

Materials science continues to occupy a central place in our lives primarily through the design and creation of new materials, and our quality of life has improved over time thanks to the discovery of new materials. Major milestones in the advancement of our society are intimately associated with materials throughout history: the stone age, bronze age, iron age, steel age (industrial revolution...
