Electrospun Membranes

The aim of this research was to develop new electrospun membranes (EMs) based on polycaprolactone (PCL) with or without metronidazole (MET)/nano-hydroxyapatite (nHAP) content. New nHAP with a mean diameter of 34 nm in length was synthesized. X-ray diffraction (XRD) and attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR) were used for structural characterization of precursors and EMs. The highest mechanical properties (the force at maximum load, Young’s modulus and tensile strength) were found for the PCL membranes, and these properties decreased for the other samples in the following order: 95% PCL + 5% nHAP > 80% PCL + 20% MET > 75% PCL + 5% nHAP + 20% MET. The stiffness increased with the addition of 5 wt.% nHAP. The SEM images of EMs showed randomly oriented bead-free fibers that generated a porous structure with interconnected macropores. The fiber diameter showed values between 2 and 16 µm. The fiber diameter increased with the addition of nHAP filler and decreased when MET was added. New EMs with nHAP and MET could be promising materials for guided bone regeneration or tissue engineering.

Biodegradable Poly

A biodegradable poly (glycerol-glycol-sebacate) terpolymer (PGGS) with different composition is prepared by a three-step method. The structure and properties of the PGGS terpolymers were characterized by means of attenuated total reflectance-Fourier transform infrared (ATR-FTIR), differential scanning calorimeter (DSC) and X-ray diffraction (XRD) methods. The experiment results indicate that the the composition of terpolymers have an obvious influence on the structure of PGGS terpolymers. The degradation rate increases with the increasing crosslink degree of PGGS.
