Iranian Company Makes Nano Heater without Element to Prevent Steaming in Mirrors

This heating pad operates without the use of electrical elements. Its structure uses a conductive paste containing nanoparticles that, after printing on a polymer sheet and passing current, produces mild heat and transfers it to the mirror surface and therefore, water vapor evaporates from the mirror and the user's vision remains clear.

The use of nanotechnology in this product has significantly improved its conductivity. A comparison of laboratory samples shows that the electrical resistance of the printed circuit with conventional pastes was about 467 ohms per square, while this number has been reduced to 19 ohms per square in nano-pastes; in other words, conductivity is increased, and as a result, more heat is produced with less electricity consumption.

Practical tests have also shown that the temperature of the mirror equipped with this pad has increased from 23 to 44 degrees Celsius, which is quite effective in preventing fogging. This product is designed as a sticker with a small thickness that can be easily installed behind mirrors of various sizes and can even be used for mirrors in bathrooms, saunas, swimming pools and car side mirrors.

Other advantages of this product include quick installation, adjustable temperature range and element-free design, which provides high safety and durability.

In a relevant development in 2023, an industrial group in Iran used chrome and aluminum coatings with nanometer thickness to make durable mirrors for installation in environments with high humidity, including swimming pools.

According to the Nanotechnology Development Headquarters of the Iranian Vice-Presidency for Science, Technology and Knowledge-Based Economy, this aluminum mirror has been produced by using nanotechnology and layers of aluminum metal on glass.

The chrome mirror is suitable for areas and places with high humidity (bathroom and indoor swimming pools) since the chrome coating is highly resistant, and the moisture leaves a minimum impact on it. In addition, these mirrors can be used as a decorative tool for new designs or production of visual effects with various reflections.

Thanks to these features, this type of mirror can be used in bathrooms, sports halls, dining halls, hotels, conference rooms, facade panels, lighting systems, and interrogation rooms.
