Careful control of the termination step during CNT growth results in straight roots and good adhesion to the substrate, in sharp contrast to the roots of naturally terminated CNTs that are highly curved and contain trapped catalyst. Direct force measurements show that well-controlled termination gives rise to an adhesion three times larger than that of natural termination.
