1. Yen, Chung-Kun. Development of Biocompatible Polypeptide Piezoelectric Fibers by Near-Field Electrospinning Technology.

Degree: PhD, Mechanical and Electro-Mechanical Engineering, 2017, NSYSU

This study presents polypeptide piezoelectric fibers with biocompatibility by near-field electrospinning (NFES), which is inspired by the polypeptide of spider silk initially. Poly (γ-benzyl α L-glutamate) (PBLG) fiber and Poly (γ-methyl l-glutamate) (PMLG) fiber are obtained by NFES. Parameters of PBLG and PMLG fiber process are based on Poly (vinylidene fluoride) (PVDF) fiber where electrospinning solution conductivity is 44 μS/cm, electric field is 1.60Ã107 V/m, collecting gap is 1 mm, speed rate of infusion pump is 0.50 ml/hr, and tangent speed of collecting device is 2618.10 mm/s. Moreover, the blends of PMLG/PVDF with biocompatibility are obtained. Micro tensile testing, Fourier transform infrared spectroscopy (FTIR), and electricity test of the blends of PMLG/PVDF are carried out. The results show that spider silk after polarization was made to have α-helix and β-sheet of secondary structure with orderly arrangement. The open circuit voltage and close loop current of spider silk are 40.70 mV and 105 nA, respectively. The blends of PMLG/PVDF with high piezoelectric effect are fabricated successfully. The maximum open circuit voltage and close loop current of PMLG/PVDF fiber are reached to 115 mV and 173 nA, respectively. The output power of PMLG/PVDF fiber under 8 MΩ is 722 pW.
