What is thermochromic film used for?
I thought i had a new idea for energy efficiency with temperature changing paint but when i searched for it i found it already existed. My idea was to use it as a house paint. White in the summer and dark brown in the winter. Could also use it on a car which would not only have the benefits of temperature control but also if you live in an area where there is snow in the winter you would have a dark car at that time which is more visible and a white car in the summer which is more visible at that time. I had also thought about using this for coating passive solar panels. Hi,Thermochromic pigment can change color when temperature get rise,and would return back to original color when temperature drops,your idea is great,but the disadvantage of thermochromic pigment is not suit for exposing in the SUN for a long time,or would affect its color change effect,we .

What are the uses of thermochromatic ink?
Thermochromic ink changes color when it reaches a certain temperature. This change can either be temporary or permanent, depending on how the ink's made. The medical and tattoo industries really like this stuff. Both groups use autoclaves to sterilize their equipment. The companies that make autoclave pouches (at least the ones that make them with thermochromic ink) will print the word STERILE on the pouch in a permanent-change thermochromic ink that changes color from blue to black at the proper sterilization temperature, and that's trapped into a non-thermochromic ink the same blue as the pre-change thermochromic ink is. When the hospital gets the pouches, all they see is a blue bar on the pouch. They'll put the instrument they're trying to sterilize in a pouch, seal it and cook it in the autoclave. If it got hot enough, when they open the door of the machine a big black word STERILE will be written right across the middle of the blue bar. I've also heard of people at least considering printing labels for boxes of perishable foods with it. You know you can't leave stuff like meat and milk out of the fridge too long or it goes bad. A thermochromic label would change color if the food was kept out too long to be safe. You can mix thermochromic pigment into screenprinting ink. Remember mood rings? With thermochromic ink you could make a mood t-shirt. Every teenage girl in America would want one.
