3D-Printable, Highly Conductive Hybrid Composites Employing Chemically-Reinforced, Complex Dimensional Fillers and Thermoplastic Triblock Copolymers |
| 초록 |
Use of 3-dimensional (3D) printable conductive materials have gained significant attention for various applications because of their ability to form unconventional geometrical architectures that cannot be realized with traditional 2-dimensional printing techniques. To resolve the major requisites in printed electrodes for practical applications (including high conductivity, 3D printability, excellent adhesion, and low-temperature processability), we have designed a chemically-reinforced multi-dimensional filler system comprising functionalized carbon nanotubes, Surface-modified silver nanoparticles, and Ag flakes, with the incorporation of a thermoplastic elastomer. It is demonstrated that both high conductivity, 22,939 S/cm, and low-temperature processability, below 80 oC, are achievable with the introduction of chemically anchored carbon-to-metal hybrids and suggested that the highly viscous composite fluids employing the characteristic thermoplastic polymer is readily available for fabricating various unconventional electrode structures by a simple dispensing technique. The practical applicability of 3D-printable highly conductive composite paste is confirmed with the successful fabrication of wireless power transmission modules on substrates with extremely uneven surface morphologies. |
