A porous aluminum body having high porosity and a manufacturing method therefor are provided, wherein the porous aluminum body can be manufactured by continuous manufacturing steps. In the present invention, this porous aluminum body includes a plurality of aluminum fibers connected to each other. The aluminum fibers each have a plurality of columnar protrusions formed at intervals on an outer peripheral surface of the aluminum fibers, the columnar protrusions protruding outward from the outer peripheral surface. Adjacent aluminum fibers are integrated with the aluminum fibers and the columnar protrusions.

The present invention discloses a novel and inventive transparent conductive film Differing from conventional metal mesh substrates are mainly constituted by silver nanowires (AgNW), the present invention particularly designs a nano metal wire consisting of a metallic core wire, a transition layer and a protection layer, and further develops a transparent conductive film consisting of a substrate and a metal mesh layer; wherein the metal mesh layer is constituted by the said nano metal wires. It is worth describing that, a variety of experimental data prove that the thermal resistance of this novel transparent conductive film is up to 400 C.; moreover, experimental data also exhibit that the transparent conductive film can filter part of blue light portion out of a white light by 20-30%.

Reduction/oxidation reagents have been found to be effective to chemically cure a sparse metal nanowire film into a fused metal nanostructured network through evidently a ripening type process. The resulting fused network can provide desirable low sheet resistances while maintaining good optical transparency. The transparent conductive films can be effectively applied as a single conductive ink or through sequential forming of a metal nanowire film with the subsequent addition of a fusing agent. The fused metal nanowire films can be effectively patterned, and the patterned films can be useful in devices, such as touch sensors.

Systems and methods disclosed herein are directed towards the fabrication of a nanomesh composite filter (NCF) that can be manufactured according to various embodiments, all of which are intended to be fabricated in order to control the transmission, reflection, and absorption of various wavelengths bands. In particular, the disclosed embodiments may be used for heat shielding applications where certain wavelength ranges may be desirable to transmit and others may be desirable to reflect.
