| Summary: | 碩士 === 國立清華大學 === 材料科學工程學系 === 106 === Silicone rubber is one of the most common engineering plastics. Lots of related applications have been developed owing to its extraordinary chemical stability, mechanical property and biocompatibility, such as packaging and molding. On the other hand, since carbon nanotubes (CNTs) were discovered in 1991 scientists has made efforts to study tube properties and applications because of their fascinating electronic, thermal conductivity and mechanical strength. Study here focuses on silicone rubber-CNTs composites homogeneously mixed by shear stress driven three-roller device. Composites show joule heating effect and electro-resistive effect. We then design heating elements and finger motion detector based on composite; the former shows an efficient storage of heat energy at a low power input. The latter however behaves as good sensors upon straining. The fabrication here takes advantage for mass production, hence the potential in future applications.
