Embodiment Construction
[0065] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0066] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein, so the present invention is not limited by the specific embodiments disclosed below.
[0067] As mentioned in the background art, in the prior art, single-layer or multi-layer anti-reflection coatings are mostly used to achieve anti-reflection, so that only a segment of the spectrum can be used to reduce anti-reflection, and there are defects of small incident angle and poor anti-reflection effect.
[0068] Recent studies of nano-biomimetics have shown that the cornea of moths and other flying inse...

Abstract
Disclosed are a super-hydrophobic anti-reflection substrate and its manufacturing method. The super-hydrophobic anti-reflection substrate comprises: a basement, an antireflective film positioned on the surface of the basement and a low surface energy coating positioned on the surface of the antireflective film, wherein the antireflective film has a moth eye structure. The manufacturing method of the super-hydrophobic anti-reflection substrate comprises the following steps of: providing the basement; forming the antireflective film having the moth eye structure on the surface of the basement; and forming the low surface energy coating on the surface of the antireflective film. Light transmittance of the antireflective film can be further raised through formation of the low surface energy coating on the surface of the antireflective film.
Description
Technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a superhydrophobic antireflection substrate and a manufacturing method thereof. Background technique [0002] Light reflection, moisture condensation and dust pollution on the surface of materials have always been problems that plague people's daily life, and there are few technical means to solve these problems. For example, the reflection and pollution of the glass surface greatly reduce its transparency and aesthetics. Many devices in the optoelectronic field also need to reduce reflection to improve light utilization efficiency and extend their service life through the self-cleaning function of the device surface. These aspects all require super-hydrophobic self-cleaning properties and anti-reflection properties on the surface of the material. [0003] A superhydrophobic surface generally refers to a surface where the contact angle between the solid surface and water is great...
