1. process flow
The process of SCL technology can be summarized as follows: ultraviolet radiation >; C three-dimensional network structure >; Double radical reaction > three-dimensional crosslinking. Through this treatment, the mechanical properties, thermal stability, corrosion resistance and radiation resistance of polymer materials can be improved. At the same time, the preparation process of SCL technology does not use any heavy metal ions or other harmful substances, which is safe and environmentally friendly and conforms to the strategic goal of sustainable development.
2. Advantages
Compared with traditional chemical and physical crosslinking methods, SCL technology has the following advantages:
(1) Low temperature and low pressure without solvent;
(2) short time, low content and high efficiency;
(3) the selectivity is strong, and there are only cross-linking points inside the material, and the surface of the material has no reaction;
(4) The number of cross-linking points is large and evenly distributed, which has higher strength and modulus compared with the traditional process.
3. Application area
SCL technology can be used to prepare various polymer materials with excellent properties, which are applied in the fields of electronics, optoelectronics and medical treatment. For example, in the electronic field, SCL technology can prepare microwave absorbing materials with high dielectric constant and low loss tangent, which has the potential to be used in radio frequency isolation and antenna fields;
In the medical field, SCL technology can prepare a new type of bone bonding material. By adjusting the crosslinking density and the number of crosslinking sites, the Young's modulus and tensile strength closer to biological tissues can be achieved.
4. Research status quo
At present, many research institutions at home and abroad are conducting in-depth research on SCL technology. For example, researchers at the University of Tokyo in Japan successfully prepared a high-performance polymer material with high strength, fracture strain and toughness through SCL technology. Researchers from Dalian Institute of Chemical Physics, Chinese Academy of Sciences have also successfully applied SCL technology to the preparation of bionic materials and other fields.
look into the future
SCL technology is a very promising technology, which will get more attention and application in the future. For example, in the future intelligent manufacturing, SCL technology can provide strong support for the preparation of high-performance polymer materials; In the field of new material development, SCL technology can bring more innovative ideas and possibilities. In a word, SCL technology will help to promote the development of various fields and bring more convenience and opportunities to our lives.
