Microencapsulation of Thermochromic Materials

摘要: 温致变色材料的应用通常受强酸性、强碱性及环境杂质污染等因素的影响, 以酸碱指示剂和pH值变化的熔化性化合物为变色心材的微胶囊化实验条件, 探讨了微胶囊化机理.这类变色材料的微胶囊化技术将促进其应用研究.Abstract: The application of thermochromic materials is commonly restricted by surroundings, strong acid, strong base, impurity stain and other factors. The processing conditions of microencapsulation using thermochromic materials as the core were investigated. The thermochromic materials are composed of indicator and the compounds which change pH when heated. Also, the formation mechanism is discussed. The microencapsulation will promote the application of thermochromic materials.
