Abstract: The present disclosure relates to a spiropyran composite having improved mechano-sensitivity, a method for manufacturing the same, and a chromic article including the same. Particularly, the spiropyran composite is obtained by bonding spiropyran covalently to a polymer, an inorganic material or a mixture thereof to form spiropyran composite, and impregnating the spiropyran composite with a sensitivity-enhancing agent for a suitable time through a wet infiltration process to form non-polar environment at the inner part of the spiropyran composite, to cause pre-stretch and to increase a change in color or fluorescence in response to force, stress or strain, thereby providing significantly improved mechano-sensitivity. In addition, a wet filtration process is used and no expensive equipment is required to simplify the process. Further, the process can be performed rapidly within several minutes to reduce the processing time.
