Simultaneous alignment and micropatterning of carbon nanotubes using modulated magnetic field

We report simultaneous alignment and micropatterning of carbon nanotubes (CNTs) using click here a high magnetic field.It is important to prepare well-dispersed CNTs for alignment and patterning because CNT aggregation obstructs alignment.In magnetic field, highly anisotropic CNTs rotate in the direction stabilized in energy.Owing to their diamagnetic nature, CNTs suspended in a liquid medium are trapped in a weak magnetic field generated cocktail tree for sale by a field modulator; meanwhile, they align to the applied strong magnetic field.The alignment has been achieved not only in polymers but also in ceramic and silicone composites.
