Smart dimming film (PDLC liquid crystal dimming film) has a wide range of applications and many market participants in my country

Intelligent dimming film, also known as PDLC liquid crystal dimming film, refers to a film that can switch the glass between transparent and opaque by adjusting the voltage. PDLC liquid crystal dimming film has the advantages of energy saving and environmental protection, resistance to high voltage shock, good waterproofness, privacy protection, and support for high curvature. It is widely used in automobile manufacturing, construction engineering, commercial projection, medical and other fields.

According to different working principles, PDLC liquid crystal dimming films can be divided into three types: inversion type, normal type and two-way dimming type. The inversion-type PDLC liquid crystal dimming film refers to the reverse arrangement of liquid crystal molecules under the action of an electric field to achieve light-shielding and light-transmitting effects; the normal-type PDLC liquid crystal dimming film is the mainstream product in the market, which refers to the inversion of liquid crystal molecules under the action of an electric field. The molecules are directionally arranged to achieve light-shielding and light-transmitting effects; two-way dimming PDLC liquid crystal dimming film refers to a PDLC liquid crystal dimming film made by arranging liquid crystal molecules in two directions under the action of an electric field.

Microcapsule encapsulation method and phase separation method are the main preparation methods of PDLC liquid crystal dimming film. The microencapsulation method has problems such as many by-products and easy environmental pollution, and has been gradually replaced by the phase separation method. Phase separation methods can be divided into three types: solvent-induced phase separation (SIPS), polymerization-induced phase separation (PIPS), and thermal-induced phase separation (TIPS). The polymerization-induced phase separation method has the advantages of simple production process, few by-products, and easy parameter control. It is expected to become the mainstream preparation method for PDLC liquid crystal dimming films in the future.

PDLC liquid crystal dimming film is widely used in automobile manufacturing, construction engineering, commercial projection, medical treatment, etc. In the field of automobile manufacturing, PDLC liquid crystal dimming film can be used to produce automobile windows and rearview mirrors, which can block ultraviolet radiation; in the field of construction engineering, PDLC liquid crystal dimming film can be used to produce bathroom glass and balcony windows, which can effectively protect residents’ privacy. ; In the medical field, PDLC liquid crystal dimming film is mainly used to produce glass windows in wards and operating rooms. According to the “2023-2028 China Smart Switchable Film (PDLC Liquid Crystal Switchable Film) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center >》 shows that benefiting from the increasingly strong downstream demand, the market size of PDLC liquid crystal dimming film continues to expand, reaching 620 million yuan in 2022.

With the continuous improvement of industry prosperity, the number of participants in my country’s PDLC liquid crystal dimming film market continues to grow, mainly including Xingye New Materials, Zhonghe Technology, Yan’ao Co., Ltd., Feikai Materials, Chengzhi Yonghua, etc. Zhonghe Technology has independent research and development and production capabilities for PDLC liquid crystal dimming films and is a leading enterprise in my country.

Industry analysts said that as a building energy-saving material, the market demand for PDLC liquid crystal dimming film is increasingly strong, and the industry has good development prospects. In the future, as the independent research and development capabilities of local enterprises continue to improve, the application scope of my country’s PDLC liquid crystal dimming film will be further expanded. There are many types of PDLC liquid crystal dimming films. In the future, as the downstream demand gradually develops towards diversification, its industry prosperity will further increase.
