Research on the Effect of Silane Coupling Agent on New Materials
Silane coupling agents have a wide range of applications. Silane coupling agents are used to treat organic materials as well as inorganic materials. Some properties of the materials will be significantly improved after treatment with silane coupling agents. Next, ZHONGTIAN EAST FLUORINE SILICON MATERIAL CO.,LTD. will take you to see what effect and research the silane coupling agent has on new materials.
1. Application of silane coupling agent in optical materials
The focus is on the influence and analysis of the silane coupling agents on the performance of the solar cell aluminum paste. When the silane coupling agent is 2.5%, the surface tension of the organic carrier can be reduced from about 30 mN/m to 25.69 mN/m, which increases the adhesion between the aluminum powder particles and between the aluminum film and the silicon wafer, and reduces scratches and ashing, thereby reducing the contact resistance of the aluminum electrode from 0.60 Ω to 0.19 Ω.
Some scholars have focused their attention on the luminescence properties of glass, which is a stilbene 3 doped lead-tin-fluorophosphate glass modified with a silane coupling agent. The modified SnF2 powder containing stilbene 3 is mixed into low melting point lead-tin fluorophosphate glass to obtain stilbene 3 doped organic/inorganic hybrid glass, which has better projection and uniformity.
2. Application of silane coupling agents in nano-scale materials and composite materials
Composite materials are becoming more and more popular due to their excellent performance, but the inherent shortcomings of composite materials cannot be eliminated. By using the addition of silane coupling agents, composite materials with better performance can be prepared. Adding a coupling agent to the nanomaterial is like a reinforcement, which can significantly improve the performance of the material.
Sodium silicate was used to prepare nano-SiO2 emulsion, and ammonium chloride was used to control the particle size, and then blended and co-precipitated with natural rubber latex to prepare SiO2/NR composite material.
The nano-SiO2 treated with silane coupling agent is uniformly dispersed in the composite material and has good mechanical properties. In addition to inorganic composite materials, a silane coupling agent was also added in the preparation of nano-zinc oxide, using silane coupling agent kh550, silane coupling agent kh560, and silane coupling agent KH 570 to modify nano-ZnO.
Studies have shown that the modification effect of the silane coupling agent KH570 is better. After the modification, the surface of the nano-ZnO powder is coated with KH 570. The crystal form has not changed significantly but the dispersibility becomes better.
