Supercritical foaming technology enabled elastomeric microcellular polymer foams for e-skin application |
| 초록 |
A lightweight flexible elastomeric microcellular polymer foam based electronic (e)-skin has been developed through preparing the microcellular thermoplastic polyurethane foam using an environment-friendly foaming method utilizing the supercritical fluid (SCF) as blowing agent, and then fabricating a device similar to the single electrode triboelectric nanogenerator (S-TENG) by attaching one induction electrode with the unfoamed skin layer of the foam. The comparative foaming behaviors of two types of SCF viz., nitrogen (N2), carbon dioxide (CO2) have been investigated under variable temperatures (e.g., 130 and 150 oC) and pressure (e.g. 12 MPa and 15 MPa) to pursue the soft and flexible microcellular TPU foam having considerable triboelectric property. The foam (having bigger cell size and lower appearance density) derived by CO2 foaming at 150 oC has been prioritized for development of S-TENG because of enough flexibility and considerable triboelectric response. |
