a question for a new material

Have you ever seen a fantastic material called Smart Film? The scientific name of the S.F. is PDLCF。
Now, I am waiting for any friends here will come to tell me:
the most common place(street, city, country) and the most usual application this material used you have ever seen, where and when, with any personal photos, videos show me if you please.
If you are the person coincidentally who are professionally doing work related to this products, would you mind teach me its price in your local market?

Before I posted this thread I had searched where should I post, but have no idea, so I post it here, if it is not correct, please help to move. thanks alot.
