From: Biomimetic strong and tough MXene fibers with synergy between micropores and dual interfaces
a Typical stress-strain curves of MXene, MXene/PEDOT:PSS (PeM), MXene/polyrotaxane (PrM), PPM, and PPM fibers coated with a AgNW network (A-PPM). b Radar maps of the mechanical and electrical properties of MXene, PeM, PrM, PPM, and A-PPM fibers. Ashby diagrams of (c) toughness versus tensile strength (d) electrical conductivity versus tensile strength and (e) Young’s Modulus versus strain of A-PPM fibers and other conventional fibers. The data used are summarized in Supplementary Table 1. f MD simulation snapshots and strain distribution of PPM fibers. Red dashed circles highlight the molecular motions responsible for bearing concentrated strain.
