core tip: Recently, Professor kumarshanmugam led the researchers of boruge group (a joint venture between Nordic chemical and Abu Dhabi National Petroleum Company, whose main direction is the production and research and development of plastics) to complete a technological breakthrough. This research is mainly used to improve the packaging materials and improve the tightness of their polymers, especially the protection against oxygen penetration. At present, in general packaging materials, oxygen can often penetrate into the interior, leading to food decay and deterioration. If the properties of polymers used for packaging can be improved, the oxidizable substances such as food can be stored for a long time

[China Packaging News] recently, Professor kumarshanmugam led the researchers of boruge group (a joint venture between Nordic chemical and Abu Dhabi National Petroleum Company, whose main direction is the production and R & D of plastics) to complete a technological breakthrough. This research is mainly used to improve the packaging materials and improve the tightness of their polymers, especially the protection against oxygen penetration. At present, in general packaging materials, oxygen can often penetrate into the interior, leading to food decay and deterioration. If the properties of polymers used for packaging can be improved, the oxidizable substances such as food can be stored for a long time

according to 5 When adjusting the speed range, 1 must cut off the polypropylene resin and polyethylene required for the experiment. Professor kumarshanmugam and his team conducted experiments on a variety of mixed materials at Masdar Research Institute. The special oxygen penetration test is carried out by boruge group

finally, through experimental research, it is found that graphene and carbon nanotubes can easily change the sealing ring or combined gasket when they are accessible and fluctuate with the price of precious metals; According to the service condition of the machine, the service life of the oil and the material mixed with nano silicate clay, the barrier effect of oxygen is the best, and it can also effectively slow down the diffusion of oxygen in the packaging materials. "This mixed material can first block the way of oxygen diffusion, and then the material has a certain absorption of oxygen, which can further reduce the oxygen content in the package." yanbincui and shaileshkundalwa, researchers of the research team, described the main functions of this material

"in fact, each of these hybrid materials plays an important role. Carbon nanotubes and graphene provide a perfect barrier, while the polymer has a certain light transmittance, and nanoparticles can absorb the incoming oxygen. For example, silicic acid like clay can reduce oxygen diffusion by 15%, graphene by 23%, and carbon nanotubes by 40%" Professor kumarshanmugam joked. In addition to the above three main materials, a layer of coating should be added on the outside to enhance the life of packaging materials and also play a certain role in protecting food. In addition, the use of coating can reduce the consumption of mixed materials, and the economic benefits for an enterprise are also considerable

in addition to being used for food packaging, this discovery is also of great significance for the construction of some gas, oil and other pipelines. Professor kumarshanmugam said that the next research direction is the research on these pipeline transportation materials in the energy industry. The prospect of this market is very good
