Scientists from the Plekhanov Russian Economic University created biodegradable compositions based on polyethylene and various plant fillers. The new technology will create environmentally friendly packaging materials that include natural waste from various industries. The results of the research are published in the scientific edition of the Journal of Polymers and the Environment, RIA Novosti reported.<\/p>\n
Employees of the Laboratory “Perspective Composite Materials and Technologies” of the Plekhanov Russian Academy of Economics proposed a solution to this problem. They conducted a series of experiments on the biodegradation of biocomposites based on polyethylene with various plant fillers, established the regularity of the influence of the size of the filler particles on the physical properties of polymers and the rate of their biological decomposition, and created double biodegradable compositions based on polyethylene and vegetable fillers.<\/p>\n
In the role of filler, scientists use a flax bonfire, sunflower husks, wheat germ, wheat straw or sawdust, that is, industrial and agricultural waste. They learned how to treat these materials in a special way, combine them with traditional polymers (polyethylene and polypropylene) and produce polymer composite materials with vegetable fillers at the output. In addition, scientists have developed triple compositions, in addition to the listed components, an additive has been added that improves the compatibility of the polymer and the filler. As an additive, scientists suggested using a copolymer of ethylene with vinyl acetate (SEEA).<\/p>\n
“We have learned to create a new class of materials – polymer composite materials with vegetable fillers. Our materials will significantly reduce the level of pollution of nature used packaging, since we use cheap industrial waste that make up 30 to 70% of the mass of the finished composite, the cost of finished materials is obtained at or below the traditional polymers “, explains the head of the laboratory” Perspective composite materials And Technology “Department of Chemistry and Physics of the Plekhanov Rector Pyotr Pantyukhov.<\/p>\n
According to the scientist, work on obtaining such materials is now being actively conducted all over the world. As fillers, scientists in the US use kenaf, cotton, banana fibers, coffee husks, in China they try to use bamboo, in India – jute, and in Brazil – stalks of sugar cane. But the main task that faces all scientists is to combine the filler with the polymer matrix so that the resulting material possesses high mechanical characteristics while retaining biodegradable properties. Russian scientists managed to do this. Work on the creation and study of materials was carried out jointly with the NM Emanuel Institute of Biochemical Physics<\/p>\n
