While continuing to expand in traditional application fields, organic silicon materials are penetrating into cutting-edge fields such as photonics and biomedicine. In 2025, multiple disruptive technologies will make breakthroughs, which are expected to reshape the industry's value curve.


In the field of optical chips, ultra-high parallel optical computing integrated chips have emerged
The Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences, in collaboration with Silicon Treasure Technology, has developed the world's first "Meteor-1" ultra-high parallel optical computing integrated chip. This chip uses organic silicon based optical waveguide material to achieve photon computing with parallelism>100, and its energy efficiency is 1000 times higher than traditional electronic chips. At present, the chip has been verified by companies such as Huawei and Cambrian and applied in fields such as AI training and autonomous driving. It is expected that the mass production cost will be reduced by 40% compared to imported products by 2026.


Biomedical field: Biodegradable silicon-based stent approved for market launch
The PDMS-PLA composite stent developed by the team from East China University of Science and Technology has overcome the pain points of high restenosis rate and non degradability of traditional metal stents. The stent completely degrades after 6 months in the body, while releasing silicon ions to promote endothelial repair. Clinical trials have shown that the patency rate reached 98% one year after surgery, which is 15 percentage points higher than drug coated stents. In August 2025, the product obtained Class III medical device certification from the National Medical Products Administration and was exclusively produced and sold by Lepu Medical.


Energy sector: Quality production of silicon-based solid-state electrolysis is imminent
The lithium phosphorus oxygen nitrogen (LiPON) silicon-based solid electrolyte developed by the Institute of Nuclear Energy and New Energy Technology at Tsinghua University has a room temperature ionic conductivity exceeding 1mS/cm, reaching the level of liquid electrolytes. This material has excellent compatibility with silicon carbon negative electrodes, which can increase the energy density of solid-state batteries to 400Wh/kg and achieve a cycle life of over 2000 times. Ningde Times has invested 1 billion yuan to build a production line with an annual output of 5000 tons, and it is expected to be loaded and tested in 2026.


Environmental protection field: Diatom based adsorbent materials for seawater desalination
In response to the high energy consumption of traditional reverse osmosis membranes, Ocean University of China has developed diatomaceous earth organic silicon composite adsorbent materials, which achieve seawater desalination through the "adsorption desorption" cycle, reducing energy consumption by 60% compared to reverse osmosis methods. In the Rongcheng demonstration project in Shandong, this material can produce 500 tons of fresh water per day, with a cost controlled below 3 yuan/ton, providing a low-cost solution for coastal water scarce areas.


Policy support: tilted by the National Natural Science Foundation of China
In 2025, the National Natural Science Foundation of China will establish the "Silicon based Frontier Materials" special project, providing up to 50 million yuan in funding for projects in fields such as optical chips and biomedicine. At the same time, the Ministry of Science and Technology has included organic silicon materials in the key research and development plan for the 14th Five Year Plan, requiring the localization of five key technologies by 2025 and breaking foreign monopolies.


Market prospect: The market size will exceed 200 billion yuan by 2030
According to SMM's prediction, with the commercialization of cutting-edge technologies, the market size of organic silicon new materials will expand from 30 billion yuan in 2025 to 200 billion yuan in 2030, with a compound annual growth rate of 45%. Among them, the proportion of optical chips and biomedical fields will reach 40% and 30% respectively, becoming the core engines of industry growth.
