At the construction site of Linlong New Materials R&D Base in Dongming County, Shandong Province, the roaring of machines and the towering tower cranes create a busy industrial scene. The 2-micron high-end battery separator production base project with a total investment of 2.5 billion yuan is accelerating. As a key "chain main" project introduced locally, its planned land area is 173 acres, and four wet separator production lines and supporting coating separator production lines will be built. After full operation, it will form a strong production capacity of 1.5 billion square meters of single-layer and three-layer composite lithium-ion battery separators per year. It is expected to achieve an annual output value of 3 billion yuan and an annual tax revenue of 300 million yuan, injecting core material supply capacity into the new energy industry chain.

Thermotropic liquid crystalline polyarylester (TLCP) is a polymer material with broad application prospects. It exhibits excellent thermal and mechanical properties, as well as stable size and low dielectric constant. Therefore, it has broad application potential in high-tech fields such as aerospace, national defense and military industry, fiber optic communication, electronic appliances, etc. However, TLCP is a typical insulating material that has problems such as weak response to external electrical stimuli, single functionality, and poor photothermal conversion efficiency. Therefore, in order to improve the response ability of TLCP to external stimuli, nano composite modification was adopted to enhance its conductivity and photothermal conversion efficiency.

In order to screen excellent bamboo species suitable for promotion and planting in northern Guangxi, the growth adaptability of three medium-sized bamboo species in the genus Dendrocalamus Sapidus, D. minor var. amoenus, and D. minor was compared and analyzed for three consecutive years. The results showed that all three bamboo species exhibited good adaptability to the natural environmental conditions in northern Guangxi. Among them, Qingtian bamboo, as a local bamboo species, has a large number of new bamboo shoots every year and a fast growth rate, making it suitable for large-scale promotion and planting. Based on various growth indicators, the adaptability of the three bamboo species in the northern region of Guangxi is as follows: Sweet bamboo>Flower hanging silk bamboo>Hanging silk bamboo.

With the advancement of global plastic restrictions, biodegradable materials have become an important direction for solving white pollution. Starch has become a research hotspot due to its renewable, low-cost, and fully degradable characteristics. However, natural starch (NS) has problems such as strong intermolecular hydrogen bonds, high hydrophilicity, and poor processing performance. By acetylation modification, the polarity of starch hydroxyl groups can be disrupted, crystallinity can be reduced, hydrophobicity and thermoplasticity can be improved. Thermoplastic acetylated starch (TPSA) can be compounded with materials such as polylactic acid (PLA) and polyvinyl alcohol (PVA) to prepare high-performance films, which are widely used in fields such as food packaging and agricultural coverage.

In the precise world of optical instruments, the direction of each beam of light, every reflection and transmission, are related to the performance of the instrument. Spectrometers, interferometers, and other key equipment in the field of optics have extremely high requirements for the performance of optical components.

Recently, Apple's major suppliers have successfully overcome the challenge of AR glass nano coating technology, reducing the glass reflectivity to below 0.5%, bringing significant breakthroughs to the improvement of display effects for Apple MR (mixed reality) devices. This achievement is not only expected to significantly improve user experience, but also to drive technological upgrades in the entire MR industry.

As mobile phone screens evolve from 720P to 2K/4K resolution, breaking through from 60Hz refresh rate to 144Hz high refresh rate, iterating from straight face screens to foldable and surround screens, consumers seem to have become accustomed to the "arms race" of manufacturers in screen parameters.

Transparent components often face critical visibility issues such as reflection and atomization formation. Anti reflection strategies have been developed to improve transparency and reduce reflection.

Due to its photocatalytic self-cleaning properties, titanium dioxide modified anti reflective coatings (ARCs) on photovoltaic glass have become a research hotspot. However, balancing the optical performance, photocatalytic performance, weather resistance, and process complexity of composite nano coatings remains a challenge.

Optical coating technology is a core technology in the field of optics. It precisely controls the reflection, transmission, and interference behavior of light at the interface of the medium, endowing optical components such as lenses with "superpowers" - from improving imaging quality to protecting component life. Its applications cover many fields such as consumer electronics, aerospace, medical equipment, etc. This article will analyze the mysteries of optical coating from multiple aspects, including basic concepts, the core role of optical coating, typical coating processes, and introductions to well-known coating equipment manufacturers.

Polarizers, as key "optical switches" for liquid crystal displays (LCDs) and even some OLEDs, directly determine the brightness, contrast, color, and lifespan of the screen based on their performance. This seemingly simple "sandwich" structure (TAC protective layer/PVA polarizing layer/TAC protective layer/functional adhesive/PET release film) actually embodies cutting-edge technologies such as polymer physics, precision coating, optical design, and chemical treatment.
