Direct Writing of Patterned, Lead‐Free Nanowire Aligned Flexible Piezoelectric Device

Direct Writing of Patterned, Lead‐Free Nanowire Aligned Flexible Piezoelectric Device

A high-performance flexible piezoelectric nanogenerator (PNG) is fabricated by a direct writing method, which acquires both patterned piezoelectric structure and aligned piezoelectric nanowires simultaneously. The voltage output of the as-prepared PNG is nearly 400% compared with that of the traditional spin-coated device due to the effective utilization of stress. This facile printing approach...

Micropatterning: Direct Writing of Patterned, Lead‐Free Nanowire Aligned Flexible Piezoelectric Device (Adv. Sci. 8/2016)

Flexible piezoelectric PMN-PT nanowire-based nanocomposite and device.

Piezoelectric nanocomposites represent a unique class of materials that synergize the advantageous features of polymers and piezoelectric nanostructures and have attracted extensive attention for the applications of energy harvesting and self-powered sensing recently. Currently, most of the piezoelectric nanocomposites were synthesized using piezoelectric nanostructures with relatively low piez...

Monolayer resist for patterned contact printing of aligned nanowire arrays.

Large-area, patterned printing of nanowires by using fluorinated self-assembled monolayers as the resist layer is demonstrated. By projecting a light pattern on the surface of the monolayer resist in an oxygen-rich environment, sticky and nonsticky regions on the surface are directly defined in a single-step process which then enables the highly specific and patterned transfer of the nanowires ...

Patterned growth of vertically aligned organic nanowire waveguide arrays.

Vertical nanowire arrays were prepared from an organic dye compound, 1,5-diaminoanthraquinone (DAAQ), on various types of substrates by a facile physical vapor transport method. It was found that the DAAQ grows much faster on the substrates with higher surface energies. Therefore, patterned growth of the nanowire arrays was achieved by modifying the substrate surfaces both geometrically and che...
