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.
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都会自发组装成扭结螺旋、环和“网球拍”形状。我们表明，细长的几何形状比任何分子细节对形态的决定作用更为重要。我们的介观连续介质理论能够量化对这些结构的观察结果，并且表明它们也会出现在其他丝状组件中。
