Coaxial Electrospinning of Miscible PLLA-Core and PDLLA-Shell Solutions and Indirect Visualisation of the Core-Shell Fibres Obtained

摘要

Core-shell fibres of semi-crystalline poly(L-lactic acid) (PLLA) (core) and amorphous poly(D,L-lactic acid) (PDLLA) (shell) were produced through the coaxial electrospinning of two miscible solutions. Due to the poor contrast between the PDLLA and PLLA, t
