Are PDLCs only available as artificial materials?

Not at all; common examples of natural occurrences of liquid crystals include proteins, soaps, detergents, and even some types of clay.

?

How does smart glass/film works?

Smart glass works via electrical signal through activation of switches, sensors etc. Liquid crystal molecules turn to allow light to pass through and glass becomes transparent. It is opaque when not activated.

what is the difference between self-adhesive smart film and smart glass

1. What is self-adhesive smart film and smart glass

Self-Adhesive Smart Film:

A flexible polymer-based film (typically PDLC: Polymer Dispersed Liquid Crystal) with an adhesive layer on one side. It is applied directly to existing glass surfaces like a sticker.

Smart Glass:

A laminated glass unit where PDLC film is permanently sandwiched between two layers of glass using EVA or PVB interlayers under high pressure/temperature. This creates a solid, structural glazing product.


2. Installation & Application

Feature Self-Adhesive Smart Film Smart Glass
Installation Peel-and-stick onto existing glass; DIY-friendly. Requires professional glazing; replaces entire glass unit.
Best For Retrofitting existing windows/glass partitions. New constructions or full renovations.
Complexity Some skill is needed:
1. How to install the film;
2. How to deal with the edge sealant;
3. How to hide the wire.

How to install the self-adhesive smart film?

Install the glass as the normal glass except for considering how to hide the wire.

3. Functionality & Performance

• Optical Clarity:
Both switch between transparent (ON) and opaque (OFF) via electricity. Smart Glass often has higher clarity due to glass encapsulation.

• Energy Efficiency:
Identical function: Blocks ~99% UV rays and reduces heat gain.
Power consumption is low (~5W/m²/hour).

• Durability:
Smart Glass is more robust (scratch resistant, impact-resistant, safety-glass properties, longer life time). Film is vulnerable to peeling/scratches comparing with smart glass.

• Safety:
Smart glass remains secure after breaking. Film lacks structural security but can prevent glass from shattering.


4. Applications

• Film: Ideal for retrofitting offices, shower doors, storefronts, or rental properties.

• Glass: Suited for high-end architectural projects (facades, security rooms, partitions), automotive sunroofs, and aviation.


5. Pros vs. Cons Summary

Type ✅ Pros ❌ Cons
Self-Adhesive Film Affordable, easy install, UV/heat blocking, retrofit-friendly Less durable, no structural safety, prone to air bubbles, Lower clarity than smart glass.
Smart Glass Premium finish, enhanced safety/durability, seamless integration, higher clarity and performance than film. High cost, inflexible for existing spaces, complex replacement.

Conclusion

Choose self-adhesive smart film for cost-effective, non-invasive upgrades to existing glass. Opt for smart glass in new builds or high-traffic areas demanding durability and safety. Both deliver dynamic privacy/energy savings but cater to different project scales and budgets.
