Fabrication of biodegradable nanofibers via melt extrusion of immiscible blends
نویسندگان
چکیده
Abstract Polylactic acid (PLA) and poly(3-hydroxybutyrate- co -4-hydroxybutyrate) (P(3HB- -4HB)) nanofibers were prepared by melt extrusion of immiscible blends PLA/polyvinyl alcohol (PVA) P(3HB- -4HB)/PVA via in situ formation microfibrils during the process. The morphology after removal PVA with water was studied using scanning electron microscopy. intermolecular interactions Fourier-transform infrared spectroscopy. compatibility components PVA/PLA better than that PVA/P(3HB- -4HB) blends. By varying process conditions, average diameter PLA could be controlled range 78–150 nm 274–424 nm.

Impact, thermal and biodegradation properties of high impact polystyrene/corn starch blends processed via melt extrusion
High impact polystyrene (HIPS)/corn starch blends were prepared in presence of glycerol as a plasticizer via melt extrusion process by a twin-screw extruder. The novelty of this work is first, because of the use of pre-gelatinized corn starch as modified one and second, the procedure of making blends by extruder which makes it ease of access and also industrially possible. The blends were then ...
