US research found that waste sulfur can be converted into new plastics
it is reported that a scientific research team of Arizona State University in the United States said in the latest issue of nature · chemistry that if oil leakage is found, they have developed a new chemical process "reverse vulcanization process", which can convert waste sulfur into light plastics. The new plastics can be used to manufacture sulfur lithium batteries with better performance
the study leader Jeffrey pine, associate professor of chemistry and biochemistry at Arizona State University, said: "the new reverse vulcanization process is simple and useful. The next generation sulfur lithium batteries made of new plastics can be widely used in electric vehicles, hybrid electric vehicles and military fields. Compared with the sulfur lithium batteries currently used, they are more efficient, lighter and cheaper. New plastics can be easily and cheaply manufactured in large quantities."
although sulfur is widely used in industry, after oil and natural gas are refined into clean fuel, the amount of residual sulfur far exceeds the required amount, and most of the sulfur is still discarded. Jered greibel, a co-author of the study, said that for every 19 gallons of gasoline produced, about half a pound of sulfur remained. The latest research has found a place for these waste sulfur
pine has been studying how to use chemical methods to make these waste sulfur meet people's needs for excellent sulfur lithium batteries. The new method can turn liquid sulfur into useful plastics that can be easily industrialized
however, the performance of sulfur itself poses a challenge to this idea: sulfur is not easy to form stable molecular long chains (polymers), and these molecular long chains are necessary to make a plastic suitable for molding; In addition, most substances are insoluble in sulfur. After a series of experiments, scientists found the chemical substance that can polymerize with sulfur, which is most beneficial to the molding of plastic parts. They named this polymerization process "reverse vulcanization process" because the oil delivery valve can be opened larger at the beginning. The reaction requires a lot of sulfur and a small amount of additives. The vulcanization process is to add a small amount of sulfur to a large amount of rubber, so as to make the rubber more durable
the results showed that the performance of the new plastic in the battery was better than that of sulfur, because the battery with sulfur cathode had very limited charge and discharge times. Pine said that several companies have expressed interest in their new plastics and new batteries. Next, they plan to compare the characteristics of new plastics with existing plastics and explore whether they can show their strengths in other fields such as optics
