Abstract

We have synthesized new bio-based polyureas (PUs) using 4-aminophenylalanine (4-APhe) as a diamine monomer bioavailable by fermentation of genetically modified Escherichia coli. Most of PUs are processable into films or fibers having excellent mechanical properties; mechanical strength at maximum around 150 MPa and strain energy density around 10 J/cm3 at maximum, which means that PU much tougher than those of conventional bioplastics.
