Polymerized cyclic butylene terephthalate/multi-walled carbon nanotube composite film fabricated by a one-step process for electromagnetic interference shielding effect |
| 초록 |
To apply composite incorporating multi-walled carbon nanotube (MWCNT) as an electromagnetic interference (EMI) shielding effect material, a composite manufacturing process capable of uniform dispersion is required. In this study, multi-walled carbon nanotubes (MWCNT) and in-situ polymerizable oligomer resin with low melt viscosity were used to fabricate composite films in a one-step process. Polymerization of the fabricated nanocomposite films was determined by crystalline structure and thermal behavior analysis. We also evaluated the electrical conductivity and electromagnetic EMI shielding properties of fabricated composites and compared them with theoretical results. The measured electrical conductivity of films showed 4.33 S/cm at 7 wt% filler incorporation with percolation threshold at 1 wt% MWCNT content. EMI shielding effectiveness (SE) values of the composites by the proposed process increased with the MWCNT content, and exhibited 30 dB at filler incorporation of 7 wt%. |
