Piezoresponsing Ability of Electrospun PVDF and Polyurethane Nanofiber Web for Mechanical Sensor Applications |
| 초록 |
We could obtain piezoelectric PVDF nanofiber web through electrospinning of polar aprotic mixture solution of PVDF and metal salt. Piezoelectic property of this PVDF nanofiber web was measured using a voltage or a charge mode amplifier together with an external force applying apparatus. Since large amount of air is contained in the PVDF nanofiber web, it also showed good piezocapacitive property responding to the external force dynamically and statically. Even though electrospun polyurethane nanofiber web did not show piezoelectricity, it showed very good piezocapacitivity both statically and dynamically. The hysteresis of the force-capacitance curve for the polyurethane nanofiber web is much less than for the PVDF nanofiber web due to high elasticity of polyurethane. Acknowledgment.
