Energy model of bilayer nanoplate scrolling: Formation of chrysotile nanoscroll

Energy model of formation of multiwall nanoscrolls from thin layers has been proposed. The three major factors favoring the scrolling are dimensional mismatch of the crystal lattices forming the bilayer, difference of the surface energy at the bilayer sides, and the interaction between the bilayers. Optimal cross-section geometry of the finite-length nanoscrolls with chrysotile structure has been simulated. Effects of the Young’s modulus, specific surface energy, and adhesion energy on the nanoscroll morphology have been considered.
