Abstract
In this study, we have examined a mechanism to fabricate cellulose nanofiber actuators using conducting fabrics. The conducting fabrics were successfully attached to both the layers of 2,2,6,6-tetramethylpiperidinyl-1-oxyl radical (TEMPO)-oxidized cellulose nanofiber (TCNF) films using a simple heat-press method,and the obtained actuators functioned as bending-type actuators. TCNF exhibits a polyelectrolyte structure and can induce iontophoresis under an applied electric field. The observed bending motion of the TCNF actuators can be attributed to iontophoresis when an electric potential was applied. The fabrication method reported herein does not require the usual electroless plating processes but requires only the simple heatpress processes to adhere the conducting fabrics onto the TCNF film. It is expected that this simple approach will result in new possibilities and promote the development of polymer actuators based on cellulose nanofibers.
木材のパルプから、酸化触媒により解繊したセルロースナノファイバーの構造上の特徴を活かして、高分子アクチュエータを創製する研究の論文を発表しました。この論文のポイントは、電極材を工夫することで、セルロースナノファイバーを膜材として使って高分子アクチュエータ（人工筋肉）を簡単に創製出来ることです。
