SEM image of the 3D helicoidal structure with 15° rotations between each layer. (a) SEM image showing cross section of the samples with a few stacked layers of fibre aligned at different direction at 95x magnification (the red-dashed lines are to indicate the boundary between layers), demonstrating of the basic feasibility to synthesize the full 3D helicoidal fibre structures similar to the natural material; (b) SEM image of the sample viewed from the top.
