概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
In order to improve the mechanical properties of the carbon-based electromagnetic shielding film, a problem that needs attention is that the carbon nanotubes need to have effective stress transfer when subjected to external force. The key point of the problem is that the interaction force between the carbon tubes is relatively weak. So far there is no effective way to solve this problem. Since Silicon could react with carbon nanotubes under high temperature, in this research, we plan to investigate the mechanical and electromagnetic shielding properties of the silicon modified carbon nanotube composite film.
実験 / Experimental
Carbon nanotube (CNT) is dispersed with Silicon monoxide (SiO) powder with different weight content. After that, the mixture was transferred into a corundum crucible covered with a cap. Then, the mixture was treated under high temperature (1300, 1500, 1650oC).
結果と考察 / Results and Discussion
According to Raman and XPS analysis, appriparate temperature is needed to achieve the disproportionation reaction between the CNT and SiO. What's more, when a composite film contaning a certain content of SiO was heated under similar temperature, the SiC signal peak in XPS and Raman were not found. However, when a cap was covered on the corundum crucible, a subtle SiC signal peak could be detected. Based on this results, it seems important to construct at least a subtle positive pressure in this system because the SiO is easy to vaporate during the heating process.
