Outline of Final Research Achievements

The sensitization of the irreversible change to the hydrophobicity ⇒ hydrophilicity was achieved in the surface wettability controllable polyimide by photo-irradiation applicable for printed electronics. In addition, it succeeded in newly developing the polyimide which reversibly switches the hydrophobic ⇔ hydrophilicity by the photo-irradiation. And, the examination , which applied this study in the biomedical field with the significance in which the wettability control of the surface is important as application field, was carried out. The advantage of this polyimide in plant cell culture and plant protoplast cell culture was confirmed.
