Manufacture of Cnt Reinforced Polymer Composites Using Nanofibers Containing Cnt

Carbon nanotubes (CNTs), discovered by Japanese scientist Sumio Iijima, have outstanding material properties such as mechanical, thermal, electrical, and magnetic properties. For example, CNTs are not only lighter than common irons, but also 100 times stronger than the irons. However, CNTs are so tiny, that is, surface area per volume is relatively large. Consequently, they tend to agglomerate. The tendency makes it difficult to apply the outstanding properties to advanced polymer composites. To utilize the properties ultimately, aggregation tendency and alignment problems should be overcome.
