제목 Polyurethane/Polyvinylidene Fluoride Blend Electrospun Nanofiber Web Based Hybrid Tactile Sensor
초록 Electrospun polyurethane (PU) nanofiber webs (NFw) having very high amount of nano-sized open cell can be used as a piezo-capacitive sensor due to excellent electrospinnability and very good elastic properties that has been reported in our previous study. In contrast, electrospun PVDF exhibits high β-crystalline phase content and superior piezoelectricity. Consequently, in this study, PU/PVDF blends under controlled compositions were electrospun to obtain PU/PVDF hybrid NFw. These hybrid sensors are capable of measuring piezocapacitive properties as well as simultaneously piezoelectric properties. Moreover, AgNO3 was added into PVDF e-spun solution which acts as Ag-NPs in PVDF NFw to get enhanced piezoelectric performance of the hybrid sensor. Around 25% addition of PVDF into PU solution in the presence of Ag-NPs greatly enhance the peak-to-peak piezoelectric output voltage (Vp-p) along with 4.2% hysteresis and pressure-capacitance change of over 55 pF.
