During the 12th Five Year Plan period, the rubber field will establish key research directions

"in the next 5 to 10 years, the rubber field is expected to make major progress and breakthroughs in 13 aspects. During the 12th Five Year Plan period, the research in 11 research directions and 6 cross cutting fields in the rubber field will be given priority support." At the fourth China rubber basic research symposium, which ended on December 6, Ma Jin, director of the organic polymer materials discipline of the National Natural Science Foundation of China, revealed the above information

according to Ma Jin, the 13 rubber fields that are expected to make breakthroughs in the future include: Based on a large number of basic research, new rubber materials can be designed directly from the computer, showing possible chain structure, aggregation mechanism, dynamic characteristics and thermodynamic characteristics more accurately; New sources of natural rubber and high-performance bio based rubber; Design and preparation of new integrated rubber materials for tires with more energy saving, wear resistance and wet skid resistance; Design and preparation of new rubber materials for sealing in a wider temperature range "as one of the seven research institutions constituting the catapult network; Scientific description of the complex complex complex structure of filled and crosslinked rubber; The establishment of a new constitutive relationship between the complex structure of rubber materials and their viscoelastic energy; New principles and new characterization methods of rubber wear and friction; More energy-saving and environment-friendly new methods of rubber dispersion and processing and molding; Design and preparation of new rubber nano reinforcing agent and crosslinking agent; Liquid pouring high-performance pneumatic tire; A new generation of thermoplastic elastomer materials; New methods and principles of efficient, green and energy-saving rubber recovery; Bio elastomer materials and products with medical functions

in order to achieve the above breakthroughs, China will give priority support to the research in 11 directions in the rubber field, namely, new natural rubber from new sources and high-performance bio based rubber, new integrated rubber materials for tires, dual-use functions and special rubber new materials/rubber composites, and whether there is an electric state again; Different electrode connecting wires aim at the scientific description of different connecting complex structures, the establishment of a new constitutive relationship between complex structures and their viscoelastic energy, new principles and new characterization methods of wear and friction, new methods of rubber dispersion, new methods of processing and molding, the design and preparation of new rubber nano reinforcements and crosslinkers, new concepts of high-performance thermoplastic elastomer materials New methods and principles of efficient, green and energy-saving rubber recycling, as well as biologically functional elastomer materials and products, will receive priority support from the national innovation fund

at the same time, Ma Jin represents the qualitative description and quantitative characterization of the interaction between nanoparticles and macromolecules, the principle and new method of biological synthesis of rubber materials, the characterization of rubber complex structure and complex internal interaction, and the simple method and description through blending and hot pressing, biological functional elastomer materials and products, new methods and new technologies of rubber processing (including recycling) The consumption trend of new equipment and new synthetic rubber determines that plastics will have great potential in the market in the future! Learning these six interdisciplinary key directions will also be the research focus in the next few years
