温变颜料（二）

Thermochromic Pigments （ Ⅱ ）

温变颜料就是颜料的颜色随着外界的温度改变而改变，文中介绍了温变颜料的类别，可分为有机化合物、无机化合物、高分子化合物、液晶四大类，根据颜色的变化有可逆性与不可逆性两种，并介绍了温变颜料的变色机理及应用。

Colors of thermochromic pigments change with temperature, this paper introduces the thermochromic pigments categories, it can be classified into four categories： organic, inorganic matters, polymer and liquid crystal, the color change can be either reversible or irreversible and often requires microencapsulation to protect the components as to ensure the thermochromic performance.
