When decorating a new home, I look forward to the sunshine in the living room; Driving on the road, eager for clear vision of windshield without glare; Install photovoltaic panels, hoping that every ray of sunlight can be converted into electric energy... But the reflection on the surface of ordinary glass has always discounted these expectations. Can the polymer antireflection and high permeability membrane, which has been frequently recommended recently, really solve these problems and significantly improve the transmittance? With the same doubts as everyone, we conducted a practical comparative test in conjunction with professional laboratories.
1、 Why pay attention to light transmittance? What troubles will reflective light bring?
Before learning more about polymer antireflection and high permeability films, let's talk about the impact of light transmittance on our lives. Imagine that the floor to ceiling windows in your living room are facing the sunny direction, but the interior is always dark. That is, the reflectivity of the ordinary glass surface is 5%-8%, which is causing trouble - a large amount of light is directly reflected away and cannot enter the room. For photovoltaic modules, every 1% increase in light transmittance may be translated into considerable power generation benefits.
For another example, when driving, the reflection of the windshield will not only cause blurred vision, but also cause glare at night and increase potential safety hazards. In the museum, the reflection of the glass display cabinet makes it difficult to see the precious cultural relics, which affects the exhibition experience. These pain points in daily life point directly to a core demand: we need lower reflectance and higher transmittance.
2、 Polymer antireflection and high permeability film, why "change light against the sky"?
To understand the magic effect of polymer antireflection and high permeability membrane, first briefly understand its working principle. The surface of traditional glass is rough, which is prone to diffuse reflection when exposed to light; The polymer antireflection and high permeability film adopts the nano coating technology, through the superposition of multi-layer optical film system and the principle of light interference, so that the reflected light can offset each other between the film layers. It is like putting an "invisibility cloak" on the glass to let the light penetrate as much as possible and reduce the reflection loss.
What's more, the polymer material of this film has excellent flexibility and stability. It can not only adapt to curved glass, but also resist the erosion of ultraviolet light, dust and temperature difference for a long time to ensure the consistent light transmission effect.
3、 The disclosure of measured data: how amazing is the effect?
In order to verify the real performance of polymer antireflection and high permeability film, we selected the common glass film, high-end glass film in the market and the leading role of this time - Polymer antireflection and high permeability film, and tested the light transmittance under the same conditions.
The test environment simulates daily scenes: in a fully enclosed darkroom, use a standard D65 light source (simulating natural light), vertically irradiate the glass samples with different films, and record the data through a high-precision transmittance meter. The results are as follows:
| Membrane type | Transmittance | reflectivity |
| Ordinary glass film | 82% | 12% |
| High end glass film | 88% | 8% |
| Polymer antireflection and high permeability membrane | 95% | 3% |
It can be clearly seen from the data that the light transmittance of the polymer antireflection high permeability film has reached an amazing 95%, which is 13% higher than that of the ordinary glass film, and the reflectivity is reduced to 3%, which is almost close to the theoretical limit. What does this result mean? Taking the 100 ㎡ sunlight room as an example, after using the polymer antireflection and high permeability film, the natural light energy received in the room is nearly 15% more than that of the ordinary glass film, which is equivalent to enjoying 2 hours of "sunshine bath" every day.
4、 Real scene measurement: the effect is visible
In addition to laboratory data, we also went into the homes of real users to record the actual performance of polymer antireflection and high permeability membranes.
Scene 1: home decoration living room
In the south facing living room of Mr. Zhang's house, before installation, the midday sunlight enters the room through ordinary glass, and the light intensity is 8000lux; After replacing with polymer antireflection and high permeability film, the light intensity directly soared to 11000lux, and the indoor brightness increased by nearly 40%. Mr. Zhang sighed: "in the past, lights were turned on during the day. Now the problem of TV reflection has been solved. Children don't have to worry about lack of light when doing their homework."
Scenario 2: photovoltaic power station
After a photovoltaic power station covered the module surface with polymer antireflection and high permeability film, after a month of monitoring, the power generation increased by 8.7% compared with the area without film. According to the annual generating capacity of 5million kilowatt hours, the power station can generate 435000 kilowatt hours more each year, which is equivalent to saving 130 tons of standard coal and reducing 340 tons of carbon dioxide emissions, achieving both economic and environmental benefits.
5、 Choose the right membrane and avoid these pits
Although the effect of polymer antireflection and high permeability membrane is remarkable, the market is mixed. How to avoid stepping on the pit? Remember these three points:
1. check the test report: ask the merchant to provide the light transmittance and reflectivity test report issued by the third-party organization, and refuse to "talk without proof".
2. hand feeling and toughness: the high-quality film has a smooth hand feeling and is not easy to deform when gently pulled; Poor quality membrane is prone to fold or fracture.
3. pay attention to the warranty period: regular brand polymer films usually provide a 5-10-year warranty, and products with short warranty period should be carefully selected.
6、 Conclusion: the data will not lie, and the effect of seeing is believing
From the precise data in the laboratory to the real feedback from thousands of households, the polymer antireflection and high permeability membrane has proved its excellent performance in improving the light transmittance with strength. Whether it is the pursuit of a bright and comfortable home environment or the desire for energy-efficient commercial applications, it can bring you unimaginable changes. If you are fed up with the problem of glass reflection, you might as well experience this "translucent black technology" to make every ray of sunlight make the best use of.
