Fabrication and Properties of Polycaprolactone/Poly(Butylene Succinate) Blends Based on Electrospinning

Abstract

Electrospinning technology is famous for its simple preparation, and accurate and easy control of process parameters. It is widely used in ultrafine filtration membrane and biological tissue engineering support. Polycaprolactone (PCL) and poly(butylene succinate) (PBS) have good biocompatibility and are commonly used materials in electrospinning. In this study, the relationship between the electrospun sample, process parameters, and spinning solution of PCL/PBS blend system was systematically studied in an electrospinning experiment. The morphology characteristics, thermodynamic properties, and microstructure of the electrospun sample were screened by scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry, and X-ray diffraction. The optimum conditions of electrospinning with high practical value were obtained.
