ProDOT-Series — Electrochromic Polymers

Flexible electrochromics for windows, displays, and wearables

ProDOT (3,4-propylenedioxythiophene) co-polymers are a proven electrochromic material family that switch color through reversible redox chemistry coupled with ionic motion. Our ProDOT portfolio is optimized for rapid, repeatable color ↔ transparent switching with process flexibility to suit smart windows, reflective displays, wearable indicators and color-changing packaging.

Key features

  • Fast switching — engineered for sub-second to few-second response in optimized stacks.
  • High optical contrast — vivid color states and clear bleach state for maximum ΔT.
  • Printable process friendly — soluble powder for on-demand dispersion, high-solid concentrates and ink-ready dispersions.
  • Tunable color & kinetics — chemistry and formulation options to tune hue and speed.
  • Stability & handling — powder format for long shelf life; refrigeration recommended for dispersions.

Available formats

  • GZ-PDT-PW — ProDOT powder (sealed, inert packaging) — ideal for labs and bespoke formulations.
  • GZ-PDT-C — Concentrate dispersion (high-solid) — dilute to target viscosity for printing.
  • GZ-PDT-R — Ready-to-use dispersion — tuned for inkjet / screen / slot die.

ProDOT-Series — Electrochromic Polymers – Material Applications

Enabling Innovations Across Industries

Smart windows

Windows that darken or clear on command to reduce glare and keep rooms cooler.

Low-power signs & displays

Outdoor signs that change their look while using very little electricity (good for long-running ads).

Wearable status badges

Small patches or wristbands that change color to show status (e.g., “OK” vs “Need attention”).

Tamper / temperature labels

Packaging labels that change color if a product was opened or exposed to high heat.

Adaptive sunglasses / eyewear accents

Lenses or small inserts that tint automatically for sun protection or style.

Privacy glass & mirrors

Office partitions or bathroom mirrors that switch from clear to opaque for privacy.

Appliance & IoT indicator rings

Thin colored rings or strips on devices (speakers, routers) that show device state at a glance.

E-paper color accents

Small colored areas on low-power e-readers or price tags to highlight important info without bright screens.

Classroom / demo kits

Simple hands-on kits that let students or customers see the color change and learn how the material works.
