Recently, United States researchers have developed a new type of plastic, the plastic can heat an hour later converted the original molecular State. In other words, this new material can be completely recycled, contains no petroleum and can be broken down by organisms, it can change the way we use and recycling of plastics.
From United States, Colorado State University researchers develop new polymer by gamma-butyrolactone (GBL), which still exists in Superglue cleaner. For years, scientists say GBL's stable chemical structure, and cannot be converted into plastic, but the research team still managed to put it out.
A chemical expert Eugene Chen said: "previous studies have shown, the GBL monomers are not suitable for plastic, we suspect that some previous reports may be incorrect. "
Now, each of us consumes each year approximately 90 kilograms (200 pounds) of synthetic polymers, most of which are not biodegradable or recycled. And worldwide, more than 270 million tons of plastic waste generated every year, of which 18 million tons were filled into the ocean.
Although many plastics and packaging were marked "recyclable" signs, they can to some extent be reused. After human processing, the plastic material increase in life expectancy, but they cannot be changed back to the original molecular State. M & M'S iPhone 5 Case M & M'S iPhone 5 Case
Biodegradable plastics on the market still faces the same problems, they can only be part of the recovery, and in the process of extending its life cycle to produce some unwanted byproducts.
Eugene Chen said: "researchers are looking for ways to develop renewable, biodegradable polymers or plastics. But this is only one of the solutions, because from the point of view of raw material recycling, biodegradable polymer is not recyclable. "
And that is why the new bio-plastics are cause for concern. We just need to put the plastic under the high temperature of 220-300 degrees Celsius heat for an hour, it can then be converted to the GBL. Once back in form of GBL, polymerization can resume in a lingxia40sheshidu environment, monomer molecules to form polymer chains or 3D grid.
Eugene Chen and his team at the time to test this new polymer, used catalyst the molecular shape is changed. While scientists tried to do the same thing 10 years ago, but they did not know that in addition to high pressure also is there a way to turn GBL into polymers.
Researchers said they hope this new type of GBL polymers to replace traditional plastic, and are looking for a way to reduce the production costs of the new plastic. The research results have been published in the journal nature chemistry, Eugene Chen also has applied for a patent.
