Germany has developed a new type of plastic that can be recycled like waste paper
according to the German newspaper Le Monde, German researchers have developed a new type of plastic that can be recycled like waste paper
based on the preliminary calculation of the polymer of styrene and acrylate monomers, this new type of plastic adds carboxyl groups to make the molecular chain electrostatically bonded, making it another option to return them. Usually, researchers have also developed a chemical synthesis process, using all carbon long fiber composites to achieve the necessary modulus increase; But the materials received
it is reported that new plastics can be easily decomposed. Wash the shopping bags made of this kind of plastic, decompose the polymerization chain with 1% sodium hydroxide solution, and convert the carboxyl group into polymerized salt, and the plastic can be dissolved. After multiple filtration and purification, the material can meet the requirements of direct contact with food. If a weak acid is added, the material can also be reprocessed into packaging bags
it is reported that the Fraunhofer Institute of processing technology and packaging participated in the development of this new material, with a development cost of about US $150million
