由于弹性效应和界面效应之间的竞争，碳纳米管和生物细丝各自自发地组装成扭结螺旋、环和“网球拍”形状。我们表明，细长的几何形状是一个更重要的决定因素的形态比任何分子的细节。我们的介观连续统理论是能够量化这些结构的观察，并暗示它们发生在其他丝状组装以及。
Carbon nanotubes and biological filaments each spontaneously assemble into kinked helices, rings, and "tennis racket" shapes due to competition between elastic and interfacial effects. We show that the slender geometry is a more important determinant of the morphology than any molecular details. Our mesoscopic continuum theory is capable of quantifying observations of these structures and is suggestive of their occurrence in other filamentous assemblies as well.
