PDLC formulation DAKENAM

PDLC stands for Polymer Dispersed Liquid Crystal, a special type of liquid crystal material, which is a composite material made by mixing liquid crystal molecules and polymer particles.

PDLC is characterised by its ability to change the transmittance of light under the action of an electric field. In the absence of an electric field, the liquid crystal molecules are randomly arranged so that light cannot pass through and is displayed in a blurred state.  When an electric field is applied to the PDLC,  the liquid crystal molecules are rearranged and bonded to the polymer particles by the electric field,  forming an ordered structure that allows light to pass through, displaying a transparent state.  By controlling the application and removal of the electric field,  it is possible to switch between transparent and non-transparent PDLCs, thus controlling the degree of light passing through.

Due to its fast response, low power consumption, high transparency, and strong controllability, PDLC is widely used in the manufacturing of smart glass products, such as adjustable curtains, privacy glass, and smart windows. PDLC technology finds significant applications in industries such as automotive, architecture, and aerospace, providing users with enhanced privacy protection, comfort, and visual experience.

PDLC formulation Applications

PDLC Aerospace applications

Aerospace applications

PDLC technology is widely used in aircraft flight cabin glass and portholes, allowing for privacy protection for pilots and passengers as well as light control. It allows the transparency of the window to be adjusted as required to improve comfort and visibility and to effectively reduce the ingress of sunlight and UV rays.

PDLC Automotive application

Automotive application

In the automotive industry, PDLC is used in the manufacture of smart windows and roof glass. It adjusts the transparency of the windows to the needs of the driver and passengers, providing privacy and sunlight control, while improving comfort and energy efficiency inside the vehicle.

PDLC Architecture and Glass Facades application

Architecture and Glass Facades application

PDLC technology is widely used in the architectural and glass façade sector. It can be used to create smart windows, privacy glass and light conditioning systems that allow buildings to adjust light transmission according to environmental needs and user preferences, providing a comfortable indoor environment and saving energy consumption.

PDLC Medical Devices applications

Medical Devices applications

PDLC is used in medical equipment applications, such as glass isolation windows and privacy screens in operating theatres. It enables fast switching transparency to allow medical staff to observe what is happening in the operating theatre and to ensure patient privacy.

PDLC VR application

VR application

PDLC can be used to create dimmable, transparent displays or glasses. By controlling the electric field action of the PDLC material, the transparency of the display or glasses can be adjusted to provide a clear display when required and to protect the user's privacy when not required.

PDLC space exploration application

space exploration application

PDLC technology can be used to create space capsule windows and observation ports with the ability to adjust transparency. It allows the transparency of the windows to be adjusted according to light intensity and mission requirements, thereby controlling the ingress of external light and protecting the visual health of the astronauts.

PDLC FAQS

Q: What Factors Are Important For The Future of PDLC?

A: The PDLC future development has great relations with below features:

Responsiveness: PDLC needs to respond quickly when switching between transparent and non-transparent states to provide immediate results.

Long-term stability: PDLC materials need to remain stable over long periods of use and multiple switching of transparency. The structure and properties of the material should remain stable under the action of an electric field to ensure reliability and longevity.

Transparency range and homogeneity: PDLC should have a wide range of adjustable transparency and should have homogeneous transparency in different areas.

Reliability and durability: PDLC material needs to be sufficiently reliable and durable for use in different environmental conditions. It should be able to withstand external factors such as temperature changes, humidity, vibration and mechanical stress without compromising its performance.

Manufacturing costs and scale up: Reduce the cost of PDLC manufacturing and enable efficient mass production.
