Hokkaido Univ. Technology : Molded body and method for producing Polymer Crosslinked body : HK24-012
Laser irradiation enables reversible 3D processing of gels.
Hydrogel, which is one of the crosslinked polymers, is expected to be used as biomimetic materials because its hardness and water content are similar to those of living organisms. On the other hand, because of its flexibility, it is not suitable for general processing methods such as injection molding, drawing, and cutting. Therefore, methods of molding inside a mold or using a 3D printer have been devised. However, the former has a problem that it is difficult to prepare a mold and cope with complicated shapes, and the latter requires a long time for printing and is difficult to select a material. To solve this problem, the inventor has found a molding method that can be obtained by spontaneous bending by laser irradiation of the gel surface and swelling of the cut part with a solvent. Since the bending is triggered by swelling due to the solvent, for example, if a hydrogel is used, it is possible to transform the shape from a flat portable shape to a shape meeting the purpose by supplying water just before use. In addition, the present invention is most effective in a double network using water as a solvent, but the same phenomenon has been confirmed in an organogel such as rubber, and can be applied to any kind of gel.

Company information
The revenue generated from technology transfer is reinvested into universities and researchers as new research funding, which is used to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will actively promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by concluding basic technology transfer agreements with the following universities (as of April 1, 2026): - Tohoku University - Hirosaki University - Iwate University - Akita University - Fukushima University - Yamagata University - Tohoku Gakuin University - Iwate Medical University - Fukushima Medical University - Aizu University - Miyagi University - Hokkaido University - Muroran Institute of Technology - Showa Medical University - Asahikawa Medical University
