Biodegradable epoxy (B-epoxy) was prepared from diglycidyl ether of bisphenol A (DGEBA) and epoxidized linseed oil (ELO). The mechanical properties of B-epoxy composites-reinforced with Multi-walled Carbon Nanotubes (CNT/B-epoxy) were examined by dynamic mechanical analyzer (DMA), critical stress intensity factor (KIC) tests, and impact strength tests. The electromagnetic interference shielding effectiveness (EMI SE) of the composites was evaluated by means of the reflection and absorption methods. From the results, it was found that the mechanical properties of CNT/B-epoxy were enhanced with increasing CNT content, whereas the value decreased above 5 phr. CNT content. This was probably considered that the CNT entangled with each other in B-epoxy due to an excess of CNT. The EMI SE of CNT/B-epoxy was also increased with increasing CNT content, which played a key factor to determine the EMI SE. |
