Can smart glass/film be regulated to gradually change its state?
Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.
When not connected to a voltage, typically the transmittance can be as low as 2%. When connected to a voltage, it can be up to 80%, but this maximum value varies from manufacturer to manufacturer.
Yes, smart glass/film can be regulated to slowly transform from opaque to transparent or vice versa. A transformer with dimmer function is needed.
Smart glass/film is operated using 48-65VAC power supply. Transformer will be needed for 110-230V power source.
Yes, smart glass/film can be used in wet areas such as bathrooms. The edges of smart glass/film are are sealed with a non-acid silicone gel that prevent any contact with water.
How to make the busbars for smart film?
Tools：Dust-free cloth, Square resistance meter, Tape measure, Alcohol, Solder, Scissors, Film spliter, Copper foil, Tape, Brush, Silver paste, Marker pen, Squeegee, Electric soldering iron, Heat gun,Pins, Pliers
Step1: Film preparation.Lay the smart film on the glass table.
Step2: Mark busbars position.Measure and mark the position of the busbar according to the drawings on the side that busbar to be installed. The distance between the two busbars is 5-10cm and each busbar should be as long as possible.
Step3: Cut upper layer PET.Align the edge of the smart film with the glass, start from one end with the film splitter, and cut the upper layer of PET to the marked position.
Step4: Wipe off liquid crystal. Use a dust-free cloth dipped in alcohol to wipe off the liquid crystal exposed after cutting off the PET.
Note: Wipe gently, not only to remove all the liquid crystal , but also not to damage the conductive ITO.
Step5: Check ITO resistance. Use the square resistance meter to select at least 3 different points to measure the ITO after wiping, and the value should be less than 250 ohm, otherwise, the ITO may be damaged and thus the smart film may not work properly.
Step6: Apply tape. Stick the tape at a distance of 5-6mm from the edge of the film to cover the liquid crystal between the lower layer of ITO and the upper layer of PET, so as to prevent the silver paste from applying this gap and causing a short circuit.
Step7: Apply silver paste evenly to cleaned ITO.
Step8: Dry the silver paste with the heat gun. The heating temperature is about 70-100℃.
Step9: Tear off the tape pasted after heating.
Step10: Apply the copper foil carefully on the dried silver paste.
Step12: Cut off the excess part of the copper foil. In order to avoid the edges from lifting, the sharp corners of both the copper foil and the smart film are cut off.
Step13: Turn the smart film over and make another busbar according to the previous steps.
Step14: Pinning: use pliers to drive the pin into the connecting copper foil and smart film to make sure the copper foil stay with smart film.At least 2 pins for each busbars.
Step15: Solder the leads: Use a soldering iron to solder leads of the suitable length on the pin.
Step16: Power-on test: 1. Continuous power-on, power-off cycle 10 times; 2. Continuous power-on for 20 minutes. After test, check if there's any defect such as over heat and black spots.
Step17: Roll up the smart film for transport or storage.

The polymer allows the liquid crystals to be embedded into a film, which can then be sandwiched between panels of glass or plastic. The polymer has constant optical properties which do not vary across its structure, and hence is considered isotropic.
In contrast, the liquid crystal itself is anisotropic, since its optical characteristics are not constant across its structure, but rather can vary under application of an electric field.
Yes, smart glass and film can be used in moisture areas so long as the edges are sealed with a non-acid silicone gel. For bathrooms, we recommend using our smart glass product as the switchable PDLC layer is protected from water by the glass. All electrical components need to be sealed and protected from contact with moisture.
