As three-dimensional (3D) nanostructures can significantly improve the absorption capacity of photons, it is widely used in various photovoltaic devices. However, the high-cost and complex preparation process of traditional 3D nanostructures restricted its development greatly. In this paper, a new type of nanocone cluster microstructure was prepared on polydimethylsiloxane (PDMS) substrate by using a simple template process. This novel nanocone cluster microstructure can significantly improve the light transmittance and reduce the light reflection, showing superior anti-reflection property. In the whole range of visible band, the nanocone cluster microstructure effectively reduces the reflectivity of the light, so that it remains below 3.5%. In addition, this kind of cluster microstructure showed excellent superhydrophobic property and self-cleaning ability with the contact angle of 151°.

Here we proposed novel NiCo₂O₄ nanowires on carbon black layer that used as a superior electrode for supercapacitors, with an excellent pseudocapacitive performance. The NiCo₂O₄ nanowires-based electrode provide high values of specific capacitance of 3.31 F/cm² corresponding to the current densities of 5 mA/cm². The symmetrical supercapacitor based on NiCo₂O₄ nanowires-based electrode have a high areal specific capacitance of 42.6 mF/cm² corresponding to the current densities of 0.5 mA/cm². It exhibited good cycling life that the specific capacitance maintained with no decrease during 50000 cycles. Our work can be applied in mass applications of high-capacitance energy-storage supercapacitors.
