Japan E. coli "made" the most heat-resistant bioplastic

Recently, researchers from the Japan Science and Technology Agency and other agencies announced their E. coli through transgenic manipulation and light reaction and other methods, to produce about 400 degrees Celsius under denaturing bioplastics are not , are the most resistant to the current kind of plastic hot. The study will be published recent papers on the American Chemical Society journal " macromolecules " (Macromolecules) online edition .Sellotape

Joint communique issued that this plastic is transparent, hardness is particularly high, the car used in place of glass , can greatly reduce vehicle weight , saving energy , reducing carbon dioxide emissions.Washi tape

Bio- plastics from biomass for the production of raw materials such as plants , help protect the environment. But after bioplastics hardness and heat resistance are poor, it is of limited use , are generally used as a disposable material.

Japanese researchers noted that some actinomycetes secrete an amino cinnamic acid has a very strong structure . The researchers found that on the basis of this recombinant E. coli , and then use it to make sugar fermentation under natural conditions produce almost nonexistent "4 - amino- cinnamic acid ."Masking tape

Researchers of the photoreactive polymer , and the like , with a "4 - amino- cinnamic acid" take polyamic acid polymerization , followed by heating the polyamide film formed under a vacuum of 150 to 250 degrees Celsius . This film is difficult to burn , can withstand 390 degrees Celsius to 425 degrees Celsius , while the previous highest temperature resistant bioplastic is 305 degrees Celsius.

The researchers believe that , compared to petroleum-based raw materials, through a complex manufacturing process of conventional plastics , bioplastics such a relatively low cost . They prepare the future to further improve its strength , and strive for practical use.Wholesale masking tape
