Compatibility and crystallinity of electrospun aligned PHBV/PEG ultrafine fibers scaffolds

摘要

Aligned PHBV/PEG ultrafine fibers are fabricated for potential applications in tissue repair. In this paper we find that the optimum spinning parameters to prepare aligned PHBV/PEG fibers is as follows: the concentration of 8wt%, voltage at 10kv, receiving distance at 18cm, the boost speed at 0.8ml/h and the best linear velocity of the rotating drum at 9.5m/s. The content of PEG is less than 50%. In addition, we investigate the interaction between PHBV and PEG in its entirety; we also discuss the surface morphology of the blends, compatibility, thermal decomposition and crystallization behavior by the help of different test methods.
