a, Schematic illustration of an Archimedean scroll fibre. b, Optical micrograph of a hair (left) and a scrolled fibre (right). Scale bar, 100 mm. c, Representative true stress–strain curves from a 2D composite scrolled fibre, its polycarbonate (PC) control fibre, and a graphene/PC composite fibre (data reproduced from ref. 31). The volume fraction for 2DPA-1/PC is 6.9% and for graphene/PC it is 0.19%. d, Plot of modulus enhancement ((E − EPC)/EPC) versus different volume fractions of 2DPA-1.
