摘要：
In this study, microencapsulation of thermochromic systems containing fluoran dye was aimed. For this purpose, thermochromic systems containing fluoran dye, Bisphenol A and 1-tetradecanol were microencapsulated with poly(methyl methacrylate) using emulsion polymerization method. Thermal properties and thermal stability of the microcapsules were investigated by differential scanning calorimetry (DSC) and thermal gravimetric (TG) analyzes. The thermo-regulation property of the microcapsules was tested by T-history analysis consisting of temperature sensor and data logger. The temperature-sensitive reversible discoloration properties of the microcapsules were determined by photographs taken at temperatures above and below the activation temperature. According to DSC results, microcapsules had latent heat storage in the range of 152.6-185.8 J/g. It was determined that the microcapsules, which were colored below the activation temperature, lost their color above the activation temperature and exhibited reversible color change property depending on change in temperature. From TG analysis results, it was determined that microcapsules had sufficient thermal resistance for textile applications. © Chamber of Textile Engineers.
