Tohoku University Technology: Polymer coating by cold spray method: T14-018
Easy to coat polymer which is difficult to mold by injection
Ultra-high molecular weight polyethylene (UHMWPE) is a material with excellent impact resistance, wear resistance, etc. However, due to poor flowability at high temperature, the injection molding, which is a common molding method for polymer, was not simple to use. Therefore, ceramic nanoparticles (alumina, etc.) were mixed to UHMWPE, then deposited by the cold spray technique. This method has succeeded to form a thick film easily. It is expected that other polymers can be deposited in the same way by mixing ceramic nanoparticles.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): 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, and Showa Medical University.
