The weight ratios of collagen to PEO were set at 90:10, 80:20 and 70:30. Influences of viscosity and electrical conductivity on the morphology of elec¬trospun nanofibers were investigated. It was proved that nanofibers became finer and finer with the ratio of PEO content increasing. Molecular interac¬tions in collagen-PEO complex and triple helix structure of collagen were also characterized by Fourier transform infrared spectroscopy (FT-IR). lt was found that the triple helix structures of collagen were well preserved in the nanowoven matrix and there were strong hydrogen bonds between PEO and collagen.
