WebbKeywords: thermotropic; thermochromic; polymer; sun protection; solar control 1. Introduction Chromogenic materials are perfectly suited for application in solar control glazing [1-3]. The motivation for scientists and engineers to develop novel electrochromic, thermochromic and thermotropic materials is their potential technical application. Thermotropism or thermotropic movement is the movement of an organism or a part of an organism in response to heat or changes from the environment's temperature. A common example is the curling of Rhododendron leaves in response to cold temperatures.
