American chemists from the University of California were finally able to finish the job the last few years. Its result was one of the first reusable “securities”, which in just a moment can be cleaned and filled immediately. Made of paper, plastic and looks like a completely transparent film. In this case, the scientists explain that the color of the “paper” and the text that is put on it, you can change. Unfortunately, at the moment, the material can be applied only blue, yellow or green paint.
The process of printing a paper is not much different from the process of printing on plain paper. Equipment printing and graphics in general corresponds to the ordinary (to date), laser printers.
Chemists have created a reusable paper
Developed by scientists printer also allows you to erase the characters already applied to the paper. For this innovative material should be heated in the process of printing up to 115 degrees Celsius. The figure in other no problem, since laser printers heated surface of the paper at the time of applying to at least 200 degrees.
As explained by scientists from the University of California, on the creation of such a printing attribute their inspiration calfskin, which used letters in many parts of the world to spread the paper. The main and perhaps the only advantage of this “parchment” was that it could “overwrite” error. It goes with the material ports. The innovative development works on the same principle, only the polymer does not deteriorate when erasing. Now an innovative paper can withstand without noticeable damage 20 cycles of writing and cleaning. Scientists from the University of California also want to increase this figure to at least one hundred.
