The Wonders of Entanglement: Carbon Nanotube Aerogel Formation and Applications The presentation will detail efforts over the past one and a half decades to bring large-scale carbon nanotube (CNT) synthesis to fruition. Insights from the production of this unique phenomena observed in the laboratory and commercial reactors will be conveyed. The research efforts over the last decade plus have begun to uncover aerosol phenomena that are still not yet well explained, chief among them the formation of a macroscopic aerogel out of the nanoscale tubes. Efforts to quantify the criteria for aerogel formation will be explained using molecular and Brownian dynamic simulations combined with joint continuum scale models. The models provide the time scales for CNT aggregation and reorientation (akin to colloidal polymer physics models) that are the basis for the aerogel formation. The adaptive methods developed to model long CNTs (up to 1 mm) within molecular dynamic simulations will be discussed in the context of broader aerosol applications to study particle surface chemistry, coalescence and fine-scale interactions. |
