1. Molecular characteristics of hydrogen containing silicone oil
1.1 ▲ Chemical Potential Energy and Reaction Activity
Hydrogen containing silicone oil (H-PDMS) has a unique molecular structure, with its skeleton composed of alternating silicon oxygen chains (- Si-O -) and side chains densely bonded with active silicon hydrogen bonds (Si-H). Due to its unique molecular structure, hydrogen containing silicone oil can undergo various chemical reactions through the dissociation of silicon hydrogen bonds, exhibiting strong chemical reactivity. This material contains 1.6-1.8% hydrogen per gram (mass fraction) and can store up to 8000 ppm of active hydrogen per cubic centimeter. Firstly, it possesses strong reaction potential energy. The dissociation energy of silicon hydrogen bonds is about 318 kJ/mol, which means that under the catalytic action of platinum, these silicon hydrogen bonds can selectively trigger 23 chemical reactions including addition and crosslinking.
1.2 ▲ Interface modification and thermal stability
Hydrogen containing silicone oil forms a polarity gradient due to the difference in electronegativity in its molecular structure (2.20 for hydrogen and 1.90 for silicon), thereby achieving precise control of molecular level surface wettability. Due to the difference in electronegativity between hydrogen atoms and silicon atoms, a polarity gradient is formed, thereby achieving precise control of molecular level surface wettability. This material is known for its excellent thermodynamic stability, with a decomposition temperature exceeding 300 ℃. Even after working at 150 ℃ for 5000 hours, it can still maintain 98% of its original activity.


2. From laboratory to industrial application
2.1 ▲ Physical and Chemical Properties and Verification
The high molecular structure and unique chemical properties of hydrogen containing silicone oil have demonstrated excellent performance in the laboratory, which has been validated in practical industrial applications. We provide a hydrogen containing silicone oil product system with a gradient of 0.2% -1.8%, which is precisely controlled using FTIR spectroscopy (with characteristic peaks located at 2150cm ⁻¹). Through a series of rigorous tests, hydrogen containing silicone oil has demonstrated excellent industrial application value in viscosity, thermal stability, and catalytic efficiency.
2.2 ▲ Performance Enhancement Technology
Hydrogen containing silicone oil exhibits excellent catalytic performance, permeation barrier, and interfacial adhesion. Only 0.5ppm of platinum catalyst is needed to efficiently trigger the addition reaction of vinyl groups, with a conversion rate of over 99.8%. On the surface of PET film, the product can form a protective layer only 0.2 μ m thick, significantly reducing the water vapor transmission rate to 0.5g/m ² · day. The bonding strength with epoxy resin, tested according to ASTM D1002 standard, can be increased to 15MPa, effectively enhancing the interfacial bonding force.


3. Wide application and value release
3.1 ▲ New Energy and Textile Industry
In the field of new energy, hydrogen containing silicone oil significantly improves the performance of photovoltaic modules and lithium batteries. By using a specific crosslinking agent to prepare POE adhesive film, its weather resistance has been verified through 3000 hours of double 85 testing (IEC 61215), and its performance is excellent. At the same time, in terms of lithium battery packaging, our product can construct a hydrogen bond network at the interface of aluminum-plastic film, significantly improving the penetration performance, reaching 8mm, with an increase of up to 40%. In the textile industry, hydrogen containing silicone oil enhances the hydrophobicity and flame retardancy of fabrics. Through superhydrophobic treatment, we have successfully increased the contact angle of cotton fabric to 160 ° and its washability exceeds 50 times, far exceeding the AATCC 135 standard. In addition, we also collaborated with phosphorus based flame retardants to increase the LOI value to 32%, meeting the standard of GB/T 5455 for vertical combustion.
3.2 ▲ Precision Manufacturing and Daily Chemical Industry
In the field of precision manufacturing, our products have improved the performance of 3D printing technology and electronic encapsulation materials. Using 3D printing technology, we have created a water-soluble sacrificial layer with a printing accuracy of up to ± 25 μ m, which fully complies with the ISO/ASTM 52900 standard. In addition, our electronic encapsulation materials have a corona resistance life of over 1000 hours, fully meeting the IEC 60243 standard. In the field of daily chemical products, the makeup holding time and skincare efficacy have been increased. We have successfully created a 0.1-0.3 μ m hydrophobic film in liquid foundation, significantly extending the makeup holding time to 16 hours. At the same time, in the field of skincare products, we have achieved a encapsulation efficiency of up to 98% for vitamin E using microemulsion technology.
3.3 ▲ Building Protection and Special Materials
In terms of building protection, our products enhance the protective performance of concrete and curtain walls. For concrete modification, we have successfully increased its penetration depth to 5mm and significantly reduced the chloride ion diffusion coefficient by two orders of magnitude, in accordance with ASTM C1202 standard. In terms of curtain wall sealing technology, we have achieved a displacement compensation capability of ± 50% and successfully passed 3000 thermal cycle tests, meeting the GB/T 13477 standard. In addition, we have successfully prepared a high refractive index silicone resin material with a refractive index of up to 1.55, which is very suitable for LED packaging and improves its light efficiency. At the same time, we have also developed an intelligent coating with temperature sensitive color changing characteristics, with a response threshold of 50 ℃, which can be widely used in the field of industrial safety warning. The synthesis and application of these special materials have further expanded our research and development field.
