Fig. 3: Mechanochromic properties of the CLCE-SC fibres.
From: Ultra tough and high resilience mechanochromic fibres for real world stress detection
a Tensile stress–strain curves of the low modulus (LM)-, medium modulus (MM)-, and high modulus (HM)-CLCE-SC fibres. b Variation in the reflected wavelengths with different chiral dopant concentrations at 100% strain. c Photographs of the variation in the initial colours exhibited by the fibres at different dopant concentrations and their mechanochromic colour changes at 50% strain. Inset images within red dashed boxes provide a magnified view of the fiber centers. d Comparison of the LM-CLCE-SC and neat CLCE fibres under various background brightness levels. e and g POM images showing the colour palettes for the LM-, MM-, and HM-CLCE-SC fibres under 170% strain and 6 N load. f and h Variation in the wavelengths with fitting curves for the LM-, MM-, and HM-CLCE-SC fibres under 170% strain and 6 N load.
