An invisible ink and a method of making the same are revealed. The invisible ink includes anodic aluminum oxide (AAO) powder and at least one solvent. The method of making the invisible ink includes the steps of taking an aluminum substrate and carrying out anodic oxidation on the aluminum substrate at least once to form an anodic aluminum oxide (AAO) layer on a surface of the aluminum substrate, separating the AAO layer from the aluminum substrate and pulverizing the separated AAO layer to get AAO powder, and adding the AAO powder into a solvent to obtain the invisible ink.

A method of manufacturing colorful thermal insulation films is provided. A substrate is connected with a metal adhesion layer and then the metal adhesion layer is connected with a porous anodic aluminum oxide (AAO) layer. A porosity of the AAO layer is changed by pore-widening. Thereby the thermal insulation film produced shows the color by the structure color of the AAO layer. Thus no dyes and organic compounds are required to be added during manufacturing process and environmental pollution caused by these substances can be avoided. The pore-widening changes the porosity of the AAO layer and further provides convenient color adjustment so that the colorful thermal insulation film with different colors can be produced easily. Besides providing attractive appearance, the colorful thermal insulation film filters out light with specific wavelengths.

An image sensor may include a polydimethylsiloxane (PDMS) layer that is subwavelength, hydrophobic, and/or antireflective. The PDMS layer may be fabricated to include a surface having a plurality of nanostructures (e.g., an array of convex protuberances and/or an array of concave recesses). The nanostructures may be formed through the use of a porous anodic aluminum oxide (AAO) template that uses a plurality of nanopores to form the array of convex protuberances and/or the array of concave recesses. The nanostructures may each have a respective width that is less than the wavelength of incident light that is to be collected by the image sensor to increase light absorption by increasing the angle of incidence for which the image sensor is capable of collecting incident light. This may increase the quantum efficiency of the image sensor and may increase the sensitivity of the image sensor.

A method for creating colorful patterns on a metal surface by using colorless ink is revealed. First carry out a first anodizing process on a metal substrate to form a first anodic oxide layer on a surface of the metal substrate. Then coat a layer of colorless ink on the first anodic oxide layer on the surface of the metal substrate to form a colorless ink pattern mask. Later perform a second anodizing process to form a second anodic oxide layer on a part of the metal substrate without being covered with the colorless ink pattern mask. Next remove the colorless ink pattern mask and coat a metal film over the first anodic oxide layer and the second anodic oxide layer to get a colorful pattern on the metal substrate.

A method for preparing invisible anodic aluminum oxide (AAO) patterns is revealed. The method includes a plurality of steps. First take an aluminum substrate. Then anodize the aluminum substrate for the first time to get a first anodic aluminum oxide (AAO). Next perform photolithography so that a photoresist forms a pattern on the aluminum substrate with the first AAO. Lastly anodize the aluminum substrate for the second time so that a second AAO is formed on the pattern and the pattern becomes invisible.

A method for dye-free coloring of one-time anodic aluminum oxide surface is revealed. First provide a substrate containing aluminum. The substrate containing aluminum is anodized once at room temperature. The anodizing process includes a step of applying a pulse signal on the substrate containing aluminum for a first period of time. Thus a porous aluminum oxide layer is formed on surface of the substrate containing aluminum. The pulse signal includes a part with positive voltage and a part with negative voltage. Then a metal layer is deposited on the surface of the porous aluminum oxide layer. The porous aluminum oxide layer has a first interference wavelength. Next perform a linear regression of the first interference wavelength versus the first period of time. The absolute value of the slope of the regression line obtained ranges from 1.8 to 38.5. The absolute value is positively correlated with the positive voltage.
