Under the technology blessing, natural rubber transforms into a variety of new materials

Natural rubber is an important industrial elastic raw material. Its excellent comprehensive performance makes it irreplaceable. The development of new natural rubber composite materials is an effective way to extend its application field and expand its application scope. Recently, a reporter from the Science and Technology Daily learned from the Chinese Academy of Tropical Agricultural Sciences (hereinafter referred to as the Academy of thermal Sciences) that the Natural Rubber Processing Research Office of the Institute of Processing Institute has made important progress in the field of new natural rubber composite materials.

R & D of high -conductive composite fiber

MXENE (MXENE) has a very high capacitance performance and is a preferred material for preparation of storage energy fiber. However, the use of poor fiber toughness prepared by pure MXENE is difficult to meet the requirements for compilation of special materials, limiting its large -scale production and application. The Research Team of the Natural Rubber Processing Research Office of the Academy of Performing Sciences The Research Team of the Natural Rubber Processing Research Office of the Institute of Processing of the Academy of Sciences through the introduction of carbon nanotubes (CNTS) in MXENE fibers, using interface regulation and wet spinning technology to break through the high tough MXENE fiber preparation technology, develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness, and develop high toughness. High -intensity, high -conductive MXENE/CNT composite fiber.

The research results were published in the international academic journal "Carbon Carbon" in the title of "High Toughness and High -conductive MXENE Fiber Super Capacitor of Carbon Nano Tube".

On this basis, the scientific research team broke through the formula and adjusted the process to break through the ultra -fine natural rubber fiber and high -conductor MXENE/natural rubber composite fiber preparation technology. The diameter of this fiber is less than 200 microns, which is thinner than 3 hair shreds, and the elongation rate is as high as 1200%.

Dr. Tao Jinlong, the person in charge of the scientific research team, said that based on the breakdown of the continuous ultra -fine multi -functional elastic fiber technology of natural rubber, it provides a good foundation for the development of "green" ultra -high elasticity, weaving and wearable fibrous elastic electronic components.

Ink that can be used to draw circuits

MXENE is one of the ideal materials for preparation of electrical circuits and electronic flexible devices.

In response to the above problems, the Scientific Research Team of the Natural Rubber Processing Research Office of the Academy of Performing Sciences through the solvent reproduction strategy breaks through the MXENE ink preparation technology that can be stably stored at room temperature. Draw the circuit on the flexible substrate with a ballpoint pen. This circuit has fast and accurate touch, and can respond to water level measurement, and there is potential application value in the field of flexible electronic technology.

The study was published on the title of "Nano -scale" academic journal "The Environment of Flexible Electronic Products for Flexible Electronics". It is reported that the scientific research team is stealing the transformation of achievements and carried out key technologies for "printed flexible composite ink ink based on natural rubber/MXENE".

The first author of the paper said that compared with organic solvents ink, the composite conductive ink can give full play to the green and environmentally friendly advantages of natural glue aquatic solution, and realize the application of natural rubber in the field of flexible functional materials.

Preparation of high -conductive porous foam

Constructing energy storage devices with high power density and fast charging speed is the key to developing portable electronic devices. As a new type of two -dimensional high -conductive materials, MXENE has a unique advantage in the design of energy storage devices in the design of energy storage devices. However, the decrease in molecular activity hinders the transfer of electronics.

In response to the above problems, the Scientific Research Team of the Natural Rubber Processing Research Office of the Academy of Performing Sciences adopted a MXENE foam with a highly connected channel with a sacrifice template method. There are enough effective sites to speed up the rate of electronic transfer.

According to Dr. Zhang Jizhen, the Institute of Processing of the Academy of Hot Science, compared with the current commercial supercapacitors, the supercapacitors prepared by the MXENE foam showed that the electrochemical properties of traditional capacitors were far higher than that of traditional capacitors, especially in terms of power and energy density. Breakthrough.

The research results are published in the international academic journal "Small" in the field of nanomaterials based on the influence of "analytical aperture size on MXENE foam electrochemical capacitance performance". In addition, the scientific research team builds a flexible strain sensor with good sensitivity and sensing interval based on natural rubber foam and MXENE.

The relevant person in charge of the Academy of thermal Sciences said that the Natural Rubber Processing Research Office of the Academy of Performing Sciences has made significant breakthroughs in the field of high -performance special natural rubber processing. The laboratory has also added a new type of natural rubber composite material direction. Further tap the performance of natural rubber and expand its application field.
