Smart film is one of the latest technological breakthroughs, enabling glass to be instantly transformed from a clear state to an opaque state, by the flicking of a switch, providing immediate privacy and security, when required. Smart Transparent Film (STF) is also known as PDLC film (Polymer Dispersed Liquid Crystal), electrically controlled smart film, electronic curtain, etc. This kind product is based on membrane technology, to attached mixed claviform macromolecule liquid crystal and prepolymer to transparent conductive substrate, bring in current through the electrode at the edge of substrate. The latest generation of smart film provides a simple,affordable alternative to other,intelligent glass' solutions.
Smart Film Principle:
When the power is switched off the liquid crystal molecules are randomly oriented scattering light and the switchable Smart Film becomes opaque (frosted, private).
When the small electrical supply is switched on, the liquid crystal molecules align and incident light passes through and the switchable Smart Film instantly clears (transparent).When the power is switched off the liquid crystal molecules are randomly oriented scattering light and the switchable Smart Film becomes opaque (frosted, private).
PDLC Smart Products Feature:
(1). Privacy Protection:
Transparent (Power on), Opaque but light pervious (Powder off) in high switching speed. It's instantaneous to make the film from completely transparent to fully opaque or vice versa.
(2). Energy Saving:
In an energized state, only 5W low power consumption per square meter per hour. 60% infrared can be shield by smart film to reduce heat radiation and transfer; 99% of UV can be shield to protect interior furnishings from color-fading or aging, to protect personnel from diseases caused by ultraviolet radiation.
(3). Sound Proofing:
Smart film having a sound damping effect; can effectively block all kinds of noise.
(4). Diversified Control:
Smart glass is versatile and can be controlled in many ways, like a wall switch, dimmer, motion detector, light, temperature sensor, remote or remote network control.
(5). With simple structure, low cost, easy installation, and easy controlling mode, there is no need for complicated installation of curtains and subsequent clean-up.
(6). It can be equipped with any size glasses, transparent when power on, opaque when power off. It's free to switch, simple and convenient.
