Scientists discover novel formula for nylon 6.6

04/03/2016
Scientists at the US-based Iowa State University claim to have created a new type of nylon using a genetically engineered strain of yeast and an electrocatalyst to convert the sugar.

The process “opens the door to the production of a broad range of compounds not accessible from the petrochemical industry,” said co-lead author Zengyi Shao.

After simple separation and polymerisation, the engineers produced biobased, unsaturated nylon-6.6, which has the advantage of an extra double bond that can be used to tailor the polymer’s properties.

Advantages include: the reaction is performed at room temperature, it uses a cheap and abundant metal instead of precious elements such as palladium or platinum, and the other compounds involved in the reaction are produced from water.
