A detailed and comprehensive study on lotus fibers has been carried out to demonstrate its spiral structure with a side-by-side arrangement of fibrils. By using an improved testing instrument, it is found for the first time that lotus fibers show distinct micromechanical performance. Notably, a qualitative comparative analysis between the tensile process of raw and heated fibers suggests that such an excellent property is mainly derived from their structure and composition. This would hold promise in designing biomimetic functional materials.
