微胶囊化在有机可逆热致变色材料中的应用

Application of micro encapsulation in organic reversible thermo-induced discoloration

文中对微胶囊技术在有机可逆热致变色材料中的应用进行了详尽的阐述。微胶囊的制备方法通常根据性质、囊壁形成的机制和成囊的条件分为物理法、物理化学法、化学法等3大类,其中以凝聚法、界面聚合法、原位聚合法应用最广泛。目前微胶囊化技术已经在医学、农药、化工、商品防伪、涂料、油墨、食品、纺织、广告等诸多领域得到广泛应用。将微胶囊技术应用于有机可逆热致变色材料的制备过程中,可以提高有机可逆热致变色材料的热稳定性和化学稳定性,拓宽有机可逆热致变色材料的应用范围。

This thesis of microcapsule technology in the application of organic reversible cause the color change materials to compare the detailed in this paper. Preparation methods of microcapsule are usually according to the properties,the forming mechanism of cystic wall and into the conditions of the capsule can be divided into physical method,chemical and physical method,chemical method and other three categories,among them with condensed,interfacial polymerization,in situ polymerization is the most widely used. At present technology has microcapsules in medicine,pesticide,chemical industry,commodities anti-counterfeiting,coating,ink,food,textile,advertising,and many other fields is widely used. M icrocapsule technology was applied to the preparation of organic reversible heat discoloration materials process,can improve the thermal stability of organic reversible heat discoloration materials and chemical stability,enlarging the application scope of organic reversible cause the color material.
