Making Carbon nanotubes a functional material for widespread use is a very cumbersome and challenging task. Not only do CNT materials require the tubes to be well dispersed and individualized rather than in bundles but resulting material has much poorer properties than expected due to insufficient load transfer between crossing CNT. This work tries to provide insight and solutions onto both of these problems, by employing computer simulations to reveal the dual nature of surfactant mediated forces on CNT. A generic coarse grain model has been used along with a dissipative particle dynamics thermostat and implicit solvent treatment. Results illustrate that depending on the bulk concentration of surfactants and their geometry, one can control the surfatantmediated forces on tubes being able to trigger both tube gluing or dispersion. Furthermore, an adsorption study elucidating the differences between surfactant adsorption on individual tubes and their bundles has been done. Surfactants follow a superlinear synergetic adsorption isothermon individual tubes,whereas adsorb via a Langmuir mechanism on their bundles. This work provides a solid framework of knowledge and insight regarding the nature of CNT and surfactants interaction and adsorption, providing rational arguments for the design of optimum CNT materials.
