The environmental protection that the research group development that DGIST energy group studies to Lim Sang-gyu leads a senior researcher gave content of carbon of a kind of biology to be as high as 97% thermoplastic polyurethane, this is a marvelous milepost. This revolutionary technology is with Korea spin develops an academy (KTDI) new product develops the Jeon Cho-hyun joint development of the Jung Jae-hoon of the group and group of new business program, it is traditional oil radical is thermoplastic can last of polyurethane substitute, the sense is accordingly great.
Thermoplastic polyurethane is a kind of extraordinary material, because of its excellent mechanical performance (include wearability, resilience, tensile strength and tear strength) and famed. Its versatility makes its apply extensively at all sorts of lives and industrial domain, be like bag of diaphragm of industrial plank, screen, box, shoe kind, material of leatheroid kimono outfit.
Current, great majority is thermoplastic polyurethane is to use oil radical multivariate ester of cyanic acid of mellow, different and binary alcohol complex. Although oil radical raw material has superior performance, but its extraction, make, use and deal with the process can cause environmental pollution. Accordingly, the whole world explores the environmental protection that is based on raw material data substitute in effort. However, development and tradition are thermoplastic the biology that polyurethane function photograph matchs base the product is facing enormous challenge.
In the outstanding collaboration with KTDI, the research group of Lim Sang-gyu obtained major breakthrough, development gave a kind of environmental protection model thermoplastic polyurethane. To synthesize material of this kind of environmental protection, they used biology radical polyester multivariate alcohol and Ding Erchun, cast off traditional oil base material to expect.
This kind those who be based on raw material is thermoplastic polyurethane has outstanding property, include to be as high as the biology carbon content of 97% , about 120, of 000 G/mol heavy all the tensile strength of molecular quantity, 20MPa and the drawing percentage elongation of 587.2% .
Notable is, these character but with what have oil radical is thermoplastic polyurethane photograph is rivalled, what make the material of a development becomes daily life and all trades and professions to apply extensively thereby is muti_function await select material to expect. This kind of environmental protection thermoplastic polyurethane hopeful applies at carapace of diaphragm of industrial plank, screen, mobile phone, shoe kind, the many domains such as leatheroid and dress material.
Researcher Lim Sang-gyu emphasizes saying: "For the research them and existing environmental protection model thermoplastic polyurethane considers to distinguish come, they evaluated biology radical carefully adipose the chemistry of ester of cyanic acid of a group of things with common features different, heat and mechanical function, changed its content scale. Next these function and oil base thermoplastic the function of polyurethane undertook comparative. ”
He expresses hopefully, the biology that the hope develops through their research base thermoplastic polyurethane can come true to commercialize and get applied extensively, using each fields of material of fiber of tall function sex especially.
