Permanent Polarity and Piezoelectricity of Electrospun α‐Helical Poly(α‐Amino Acid) Fibers

Poly(γ-benzyl α, L-glutamate) fibers with high non-linear optical activity and thermally stable piezoelectricity are fabricated by simple electrospinning methods that apply directional shear force and electric field causing parallel alignment of helical polymer chains and permanent dipoles.
