On functional electronic thin film materials
Functional electronic thin film is a kind of thin film material with special physical, chemical or electrical properties. It can meet the functional requirements of materials in the fields of electronic information, new energy, high-end manufacturing and so on through advanced processes such as precision coating, composite modification, nano doping and so on. Its thickness is usually between several microns and hundreds of microns, and it has the characteristics of lightweight, high performance and multi-functional integration. It is the key basic material in the modern electronic industry chain.
From the perspective of function classification, common types include:
Insulation and protection: such as polyimide film and polyester film, which have the characteristics of high and low temperature resistance (-60 ℃ to 200 ℃) and voltage breakdown resistance (≥ 10kv/mm), and are widely used in the insulation layer of electronic components and the isolation film of battery modules;
Conductive and thermal conductive class: it is made by coating metal nano layer or doping conductive particles, such as transparent conductive film (ITO film, silver nanowire film), which not only maintains more than 90% light transmittance, but also has conductive performance, and is the core material of touch screen and flexible display;
Optical functions: such as brightening film and antireflection film, which can improve the brightness and contrast of display equipment through optical microstructure design, or the packaging film for photovoltaic modules to enhance the light absorption efficiency;
Adhesive function class: it is made of pressure-sensitive adhesive as the substrate and composite functional film. For example, battery tape has both viscosity and insulation, and plays a key role in cell fixation and lug insulation of power battery.
The core advantage of this kind of material is "function customization", which can adjust the weather resistance, mechanical strength, dielectric constant and other parameters according to the application scenario. For example, in the field of new energy vehicles, high temperature resistant electronic films can adapt to the harsh environment of the engine compartment; In the photovoltaic industry, UV aging resistant film can extend the service life of modules to more than 25 years; In the field of consumer electronics, flexible electronic films support the shape innovation of curved screens and wearable devices.
In 2024, the size of the global functional electronic film market has reached 9.081 billion US dollars, which is expected to grow to 14.112 billion US dollars by 2031, with a compound annual growth rate (CAGR) of 6.5%. If the scope is extended to generalized functional membrane materials (including electronic, optical, separation and other types), the global market size will reach US $58.802 billion in 2024, and is expected to exceed US $87.953 billion in 2031, with a CAGR of 5.84%, of which the proportion of the Chinese market will increase from 52.73% (2024) to 55.99% (2031).
As the world's largest producer and consumer, China's functional film material market reached 162.3 billion yuan in 2024, an increase of 8.9% year-on-year, of which electrical functional films accounted for 7.35% and optical films accounted for 39.46%. Taking Wujiang District, where caplock is located, as an example, its new material industry cluster has attracted more than 100 related enterprises, with an output value of more than 20billion yuan in 2024, and functional electronic films accounting for more than 30%.
Breakdown:
Consumer electronics: it is still the largest application market, accounting for 24.89% of the global functional membrane material market in 2024, with a corresponding scale of $14.638 billion, and is expected to reach $19.831 billion in 2031, CAGR 4.37%。 Flexible display and folding screen technology promote the surge in demand for optical films. For example, the global market scale of OLED panel protective film is expected to reach 700million square meters in 2028.
New energy vehicles: the increased penetration of high-voltage platforms (such as 800V) drives the demand for film capacitors and battery tapes. In 2024, the scale of the relevant electronic film market increased by more than 20% year on year. It is expected that the film capacitor market of new energy vehicles will reach 17.922 billion yuan in 2026.
Photovoltaic industry: the demand for weather resistant packaging film increases with the installed PV capacity. In 2024, the global PV Poe film market grew by 15% year on year, and the market share of Chinese enterprises exceeded 60%.
With the rapid development of 5g, new energy, flexible electronics and other industries, functional electronic films are upgrading in the direction of "ultra-thin, multi-functional composite, green and environmental protection". For example, biodegradable bio based films reduce the pollution of traditional plastic materials, and graphene modified films improve the thermal conductivity by more than 30%. At the same time, intelligent production and green manufacturing have become the mainstream of the industry. Caplock and other enterprises have improved their production efficiency by 30% through the whole process digital management, and adopted regenerative combustion furnace (RTO) to reduce VOCs by 98%.
With policy support, China plans to increase the self-sufficiency rate of functional film materials to 70% by 2025, focusing on breaking through the "neck" technologies such as optical adhesive film for flexible display and solid-state battery packaging materials. This dual drive of technology upgrading and market expansion is making functional electronic films the core material force to support the upgrading of the global high-end manufacturing industry.
