Abstract
Ferroelectric bio-based materials with a high water content (≈90 wt %) were not previously developed. Here, we develop hydrogels containing ≈90 wt % water, amino acids (lysine and arginine) and oleic acid. The NH and CH groups of lysine hydrogen bond water, as shown by attenuated total reflectance-Fourier transform infrared spectroscopy, yielding electrically conductive solutions. Lysine also interacts with oleic acid, yielding hard materials with a lamellar crystal structure, as revealed by synchrotron small angle X-ray scattering. Polarized light microscopy and shear rheology show that aqueous mixtures of amino acids and oleic acid are birefringent gels. These gels have a columnar, hexagonal crystal structure with 54-85 wt % water, and a bi-continuous sponge crystal structure with 89 wt % water. They are piezoelectric, as demonstrated by cyclic voltammetry. Thus, they deform and undergo crystalline phase transitions when exposed to electric fields. The piezoelectric materials developed can find use in medical applications and clean energy harvesting.
