Area of Science:

  • Materials Science
  • Optoelectronics
  • Nanotechnology

Background:

  • Glazing's role in building energy efficiency and privacy is crucial.
  • Current smart window technologies often require high voltages and fail to meet industry standards.
  • Demand for tunable optical properties in windows is increasing.

Purpose of the Study:

  • To develop a low-voltage smart glass technology with tunable haze and transparency.
  • To meet the stringent technical requirements for architectural glazing applications.
  • To enhance energy efficiency and privacy in buildings.

Main Methods:

  • Introduction of a predesigned nanocellulose fiber gel infiltrated with nematic liquid crystal.
  • Utilizing dielectric coupling to switch liquid crystal patterns with an external electric field.
  • Achieving low-voltage (<10 V) dielectric switching of optical properties.

Main Results:

  • The Haze-Switch approach allows tunable haze coefficients from 2% to 90% with high visible transmittance.
  • Achieved <2% haze in the clear state using a nanocellulose network of ~10 nm nanofibers.
  • Demonstrated suitability for window applications through characterization of color rendering index, haze, and switching times.

Conclusions:

  • The Haze-Switch material and technology meet the rigorous demands of the glass industry.
  • Envisaged products include privacy windows, skylights, sunroofs, and daylighting solutions.
  • This innovation offers a viable path towards energy-efficient and adaptable architectural glazing.
