Overview of Research
I am theoretically studying mechanical properties of highly-stretchable polymer gels. Double network gel is a good example of such polymer gels. Based on recent experiments performed by our group, we expect that the force-extension relation of a single polymer chain can be extracted from the stress-strain relation of the highly-stretchable polymer gel formed by these polymers. I am developing theory and analysis method of this technique. This approach is opposite of the conventional method by rubber elasticity theory that estimates stress-strain relation of polymer network by making use the force-extension relation of polymer chains based on statistical mechanics. This study helps understand molecular mechanism of polymer networks subjected to large deformations, and also give some insights into material design.
