Hybrid biodegradable scaffolds of piezoelectric polyhydroxybutyrate and conductive polyaniline: Piezocharge constants and electric potential study

Abstract

Hybrid biodegradable piezoelectric electrospun fibrous scaffolds based on polyhydroxybutyrate (PHB) and polyaniline (PANI, emeraldine salt) were fabricated. Fourier transform infrared spectroscopy and X-ray diffraction confirmed the presence of PANi in the structure of hybrid PHB-based scaffolds. The piezoelectric coefficient d₃₃ and surface electric potential under cyclic mechanical stress at the frequency of 4 Hz were increased in 4.2 times and 3.5 times, respectively, in the case of hybrid PHB scaffolds with the addition of 2% PANi compared with pure PHB ones.
