Certain polymeric materials are responsive to environmental stimuli such as temperature, pressure, electric field, etc. and present these changes as quantifiable variables. These materials are known as smart materials and have various applications including smart sensors in relation to thermochromic changes. These sensors are made of chromogenic materials which visually change color with respect to an external stimulus. Conventional materials have fixed emissivities which signifies that the radiance features are proportional to their surface temperatures. This in turn limits their abilities to a single thermal function. It is crucial that materials with dynamic radiative properties are developed to meet industrial and commercial demands. In this study, these dynamic mechanisms in relation to thermochromic properties of polymeric materials are evaluated. Phenomenological approaches have been utilized to simulate the emissivity of relevant polymer candidates.
