MWCNTs self-assemble into various homocentric rings in a thermo-driven self-assembly system. Closely packed and scatteredly packed MWCNT rings self-assemble on a Si-SiO2 substrate, whereas on a Au substrate smoothly packed MWCNT rings, rings with waviness, and rings with shuttle-like holes are seen to self-assemble. The dynamic self-assembly process includes convection flow and swirling flow.
