Inorganic material class.The extent of alternating temperature of organic off-color material is wide, and its color change interval can be between -20 DEG C~200 DEG C, choice
Greatly, color can be freely selected, discoloring temperature is typically relatively low, high sensitivity, and stability is good, and discoloration definition is high, relatively inexpensive, but has
Machine class off-color material has portion of material poisonous, and heat resistance is poor, is corrosive.Liquid crystal type off-color material, although to temperature and change
It is very sensitive to learn material, but when being contacted with other materials, its color changeable effect can be deteriorated, particularly have being mixed with solvent and other
Impurity in machine thing, sensitiveness are stronger；And liquid crystal is between liquid and crystalline state, is highly unstable material, processing
Relatively difficult and discontinuous, this make it that color changeable effect is undesirable, and selectivity is poor.It is inorganic relative to organic off-color material
Class off-color material has more preferable weatherability, durability and preferable hybrid process, but inorganic off-color material is present clearly
Clear degree and poor sensitivity, discoloring temperature is high and poorly reversible, metachromatism unobvious.There has been no preferable thermochromism material at present
Expect to be used for intelligent glass, responded by temperature control and carry out intelligent dimming.
