Influence of electrospinning parameters on Poly(hydroxybutyrate) electrospun me...
Correia, Daniela M.; Ribeiro, Clarisse; Ferreira, José C. C.; Botelho, Gabriela; Gomez Ribelles, Jose Luis; Lanceros-Mendez, Senentxu; Sencadas, VitorPoly(hydroxybutyrate) (PHB) obtained from sugar cane was dissolved in a blend of chloroform and dimethylformamide (DMF) and electrospun at 40 ºC. By adding DMF to the solution, the electrospinning process for the PHB polymer becomes more stable, allowing complete polymer crystallization during the jet travelling between the tip and the grounded collector. The influence of processing parameters on fiber size and...
Processing and characterization of alpha-elastin electrospun membranes
Araujo, Joana; Padrão, Jorge; Silva, João P.; Dourado, Fernando; Correia, Daniela M.; Botelho, Gabriela; Gomez Ribelles, Jose LuisElastin isolated from fresh bovine ligaments was dissolved in a mixture of 1,1,1,3,3,3-Hexafluoro-2-propanol and water and electrospun into fiber membranes under different processing conditions. Fiber mats of randomly and aligned fibers were obtained with fixed and rotating ground collectors and fibrils were composed by thin ribbons whose width depends on electrospinning conditions; fibrils with 721 nm up to 2....
