Method plays the function of discoloration sensor.The first photochromic layer 120 is formed by wet corrosion process and when the second photochromic layer 130, due to the
One photochromic layer, 120 containing sodium carbonate and phenolphthalein, be used to form the second photochromic layer 130 is the solution of the sensing compounds containing third, especially
It is aqueous solution, therefore has sodium carbonate the problem of 130 manufacturing process of the second photochromic layer reacts.Therefore, second is formed
The first photochromic layer 120 is formed after being allowed to completely dry after photochromic layer 130 just can ensure that the first photochromic layer 120 and the second photochromic layer
130 normally play the function of each layer respectively in a discoloration sensor 102.
