Can smart glass be used in outdoor applications?

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.

>>>

What is the power source of smart glass/film?

Smart glass/film is operated using 48-65VAC power supply. Transformer will be needed for 110-230V power source.

>>>

Is smart glass/film available in irregular shapes?

Yes, smart glass/film is available in all irregular shapes as you want, including curved glass.

Why is PDLC considered to be smart?

The smartness of PDLCs is a result of its ability to change its transparency (technically called the transmittance) when an electrical stimulus is applied to it. This is normally by way of an alternating voltage, which exerts an alternating electric field across the PDLC material.
Nevertheless, the PDLC is only as smart as the control system which stimulates the change, which can be driven by a push button switch, a light sensor, or a building automation system.

How to make smart glass?

How to make smart glass?
Step1. Wash and clean the glass.
Step2. Move the glass to the cleanroom for lamination.
Step3. Check the lower glass and clean possible stains.
Step4. Lay the pre-cut EVA interlayer on the lower glass.
Step5. Lay the PDLC film with busbars onto the EVA interlayer. During the process, the lower protective liner is removed. Then remove the upper protective liner. Note: Do not leave fingerprints or stains on the PDLC film.
Step6. Carefully adjust the position of the PDLC to align with the glass.
Step7. Lay out and align the upper layer of EVA interlayer.
Step8. Check and place the upper glass, carefully adjust the position of the glass to align with the lower glass.
Step9. Check the glass carefully to remove possible dirty spots and stains inside the glass.
Step10. Cut off the EVA interlayer to align with the glass.
Step11. Fix the busbars leads with high temperature tape, and wrap the glass edge with high temperature tape.
Step12. Move the glass to the next operating table.
Step13. Wrap the whole piece of glass in PET film.
Step14. Bond the PET film with silicone sealant strips to form a vacuum bag.
Step15. Set the vacuum port.
Step16. Pump the vacuum bag. Fold and firm the sides of the vacuum bag with high temperature tape.
Step17. During the pumping process, check whether the vacuum bag is leaking. After the pumping is complete, disconnect the pumping pipe.
Step18. Move the glass to the heating platform, connect the glass vacuum port to the vacuum system of the heating oven or autoclave, transfer the glass to the heating oven or autoclave, and heat the glass.
Step19. Heating. parameter settings.
Step20. After heating, remove the glass from the heating oven or autoclave. To pack and store.

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.
