       US's and the German scientist recently said that, they first developed the plastic which can be able to transform under the different wave length light , it will widespreadly use in industry, medicine and so on domains.
      The American Massachusetts Institute of Technology and German GKSS research center this achievement, publishes new one issue which recently published in the Nature magazine.The researcher introduces that, this achievement foundation is the plastic shape memory effect, also is the plastic has the limited distortion after certain temperature, may make it from the heating way to restore to the distortion before the shape characteristic.They for the first time cause the light the wave length to become the shape memory effect the occurrence condition.The researcher said that, they have mounted some photosensitive molecular groupings in the polymer lattice molecular structure, forms the molecular switch so-called.Then, they stretch the photosensitive plastic film by the external force which forms like this, simultaneously uses the specific wave length the ultraviolet radiation, this caused to mount the photosensitive molecular grouping polymer minute subnet overlapping adhesion to get up mutually.
