UPM/PHBV electrospinning create different structure through different bath ratio

摘要：

Electrospinning is a straightforward method to produce ultrafine fibers. Electrospun fibers often have beads or line typed in regular or irregular arrays. UPM (unsaturated macromonomor polyester) / PHBV (Poly -(hydroxybutyrate-co-hydroxyvalerate) blended system was electrospun to form different structure. The different ratio of ethanol/water bath solutions system were varied to control the fibers morphology from abnormity to bead structure and transfer to be the shuttle structure and final to be lines and resultant different wetting property. Beads morphology changed the contact angles of water droplet from 114.6±0.8°to 139.6±0.4°. It is shown that assisting with different bath solution, UPM/PHBV mat has not only the different hydrophobic property but also good morphology controllable.
