Formation and structures study of PHBV/chitosan composite ultrafine fibers prepared by emulsion electrospinning
关键字：PHBV; chitosan; phase inversion; emulsion; electrospinning
PHBV and chitosan are two natural materials of biocompatibility and renewability. However, they cannot be prepared by electrospinning simultaneously, because they have no co-solvent. In this work, chitosan/H2O/acetic acid solution (W) was d...

Micro- or nano-structuring of fibers by photo-embossing
关键字：photo-embossing, bi-component fiber, relief structure
Relief structures are created on the surface of fibres to generate new effects in these fibres. More specifically, photo-embossing is used to generate the relief structures and to generate a non-contact process without etching pro...
