Abstract
A color-changing polymeric material is provided. The material is formed from a thermoplastic composition containing a continuous phase that includes a matrix polymer, colorant, microinclusion additive, and nanoinclusion additive, wherein the microinclusion additive and nanoinclusion additive are dispersed within the continuous phase in the form of discrete domains. A porous network is formed in the polymeric material when subjected to a deformational strain in a solid state. The polymeric material exhibits a first color prior to being subjected to the deformational strain and a second color after being subjected to the deformational strain, the first color being different than the second color.
