Intelligent Dimming Film Based on Graphene Transparent Conductive Films
With the rapid development of China's economy and society, the country has achieved impressive accomplishments in various fields. However, the accompanying high energy consumption and pollution have become significant factors limiting China's sustainable economic development. In the "Twelfth Five-Year Plan," the State Council emphasized the importance of promoting energy conservation, emission reduction, and the development of green buildings. China's per-unit building area energy consumption is more than three times that of developed countries, with windows being the primary energy-consuming component of buildings. To reduce building energy consumption, there is an urgent need for an intelligent window product that is highly effective, practical, and meets the demands of energy conservation. The intelligent dimming film emerges in response to this trend.
1.Intelligent Dimming Film as a Key Solution for Building Energy Efficiency
China's building energy consumption accounts for 35% of the total energy consumption, and issues such as delayed action on building energy efficiency, high energy consumption, and heavy pollution have become prominent problems restricting China's sustainable economic development. The thermal loss from the exterior walls of Chinese buildings is three to five times that of similar buildings in North America, with window thermal loss being over two times higher. The commercial area of doors accounts for 20% to 30% of the building area, with glass making up 70% to 80% of the door area. About 70% of building energy consumption is lost through doors, and one-third of that is lost through glass. Radiative heat transfer is the primary mode of heat conduction, accounting for over 60%.
Since 2006, the national government has actively promoted building energy efficiency, implementing a series of policy measures. For example, the Ministry of Housing and Urban-Rural Development issued the "Green Building Evaluation Standard," which assesses new and existing buildings using three grades (stars). It includes requirements for the layout of residential buildings to ensure indoor and outdoor sunlight, lighting, and ventilation, meeting the standards outlined in the "Urban Residential Area Planning and Design Code" (GB 50180). In January 2013, the State Council forwarded the "Action Plan for Green Building" by the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development. It urged the transformation of urban and rural construction models, improving resource utilization efficiency, reasonably enhancing building comfort and livability, and advancing green building action comprehensively through policies, regulations, institutional mechanisms, planning and design, standards, technical promotion, construction and operation, and industry support. The goal of implementing building energy efficiency by 2020 was also clearly defined.
In the "Twelfth Five-Year Plan for the Development of New Materials Industry" released in 2012, graphene was explicitly listed as a key frontier new material. The plan aimed to advance research and application of nanomaterials in energy conservation and other fields. China leads in graphene research internationally, with the highest number of related patents globally, making graphene industrialization widely recognized. China's graphene industry is still in the exploration phase, determining the most suitable forms for graphene products. The intelligent dimming film is a newly developed energy-saving product for doors and windows in this context. The intelligent dimming film is a new type of optoelectronic product that integrates sun shading and heat insulation inside and outside doors and windows, providing unique light transmission and thermal insulation functions. In summer, it dynamically adjusts the solar light transmittance, controlling the transmitted light and heat effectively, peaking to lower indoor temperatures. In winter, it restores the ability of light and heat to pass through, blocking indoor heat loss. Compared to existing building doors and windows, the comprehensive energy-saving effect of the intelligent dimming film is increased by more than 30%. It can effectively overcome the single deficiency of existing low-emissivity films, which can only reduce heat radiation but lack light recovery functions. The intelligent dimming film can also change the glass color and hue according to user needs, enhancing the comfort of living or working spaces. When combined with sensors, the intelligent dimming film can achieve automatic adjustment, providing users with the optimal experience and energy-saving effects.
