碩士 === 國立中正大學 === 化學工程研究所 === 106 === In this study, we used the concept from bioinspired materials to prepare conductive, self-healing Carbon nanotube (CNT)/silicon rubber materials by using low cost and modular assembly method. We choose two component silicon rubber (ecoflex-00-35). At first, put CNT/A component and CNT/B component into PE tube separately. Then, using pre-prepared CNT/silicon rubber shell to package these tubes. When materials were damaged, the CNT/silicon rubber in notch would cure that form a mechanism of self-healing. After healing, the resistance would decrease. The elasticity would recover up to 78% after healing an hour. Besides, the Strength would recover up to 71%. Young's modulus was not associated with healing time. We can enhance the strength tough heating. The elasticity recover up to 91% and the strength recover up to 95%, after healing 60 minutes at 35°C. Young's modulus rises with healing temperature. The block-shaped, self-healing material was applied to be buffering material and it can protect glass sheet. The glass sheet can only resist the impact energy of 0.02 J, the glass sheet protected by pure silicon rubber can resist the impact of 1.39 J, and the glass sheet protected by the self-healing material can resist the impact of 13.63 J at the maximum. The protective effect is 9.8 times that of pure silica rubber and 681 times that of unprotected glass tablets.
