·论文标题1： Mushroom-shaped microfiber array by electrohydrodynamic structuring process for superhydrophobicity

·摘要： Bioinspired mushroom-shaped microfiber arrayed surface demonstrates superhydrophobicity. Such a textured surface is fabricated by an electrohydrodynamic (EHD)-based structuring process, which is a combination of hot embossing, electrically induced growing and electrowetting. First, an ordinary micropillar array is prestructured on a conductive substrate through the hot embossing process. Second, another planar plate, functioning as the upper electrode, combines the substrate and an air gap into a parallel capacitor, across which an electrical voltage is applied to generate a modulated electric field. The electrically induced Maxwell force could drive the polymer to grow towards upper electrode and spread transversely on it, forming the mushroom-shaped microfibers. Through an analysis on the early-stage kinetics of the pre-structured micropillars, we can find a suitable electrical potential to ensure the electrically-induced force is sufficient to drive the polymer growing upwards. The measured static contact angle of about 152° and contact angle hysteresis of about 11° demonstrate the superhydrophobicity of this mushroom-shaped microfiber arrayed surface.

·论文标题2：Nanowire-based flexible P(VDF-TrFE) nanogenerator for simultaneously harvesting mechanical and thermal energies

·摘要：This paper presents a high performance flexible nanogenerator based on P(VDF-TrFE) nanowire array that is capable of simultaneously harvesting mechanical and thermal energies. The nanowire array was synthesized by template-wetting P(VDF-TrFE) polymer into anodic aluminum oxide. The oriented β crystalline phase of the aligned P(VDF-TrFE) nanowires formed from nanoconfinement in AAO template nanoporous has been demonstrated by Fourier transform infrared (FT-IR) spectrum and X-ray diffraction (XRD) measurements. Under periodic mechanical bending, electric signals are repeatedly generated from the hybrid device and the measured output voltages reach 5.6V. Besides, upon exposure heat-cool condition with a temperature range of 7 K around room temperature, pyroelectric output up to 3.0V/50nA was observed and used to directly drive a LCD screen. Finally, the piezoelectric and pyroelectric output voltages were successfully integrated together under application of mechanical tapping and thermal irradiation at the same time. These results demonstrate the great potential of the flexible hybrid nanogenerator for self-powered electronic devices.
