| Summary: | 碩士 === 國立中正大學 === 化學工程研究所 === 102 === In this study, we tried to prepare gecko-liked tape by carbon nanotube(CNT) to imitate the gecko’s superior climbing ability. We also tried to realize the effect of electric charge on the loading of gecko-liked tape by inputting DC charge. Furthermore, we tried to make repeated use of gecko-liked tape by post treatment.
There are three parts in this study. First, commercial super glue was deposited on Si subtract(1×1 〖cm〗^2) by blade coating, and commercial carbon nanotubes which were sieved by 100 mesh sieve were sprayed on commercial super glue , gecko-liked tape was obtained, the mass of CNT on gecko-liked tape was about 8 mg. The loading value of gecko-liked tape after prepress treatment was about 600 – 800 g. In the second part of this study, we supplied an additional DC power on the both side of gecko-liked tape, where had been coated conductive silver adhesives, and then we measured loading value of gecko-liked tape simultaneously, the relationship between voltage and loading value was obtained. On the other side, we measured the varies of temperature of gecko-liked tape, the relationship between voltage and temperature was obtained. In the final part, in order to make gecko-liked tape reusable, post-treatment had been adopted. Gecko-liked tape could be reused for 3 to 5 times, the loading value reduced as reusable times increased.
Key word: carbon nanotube, gecko-liked tape, DC, reusability
