Mechanical and electrochemical properties of TiO2 modified polyurethane nanofibers

In this paper, TiO2 nanoparticles have been employed to improve the mechanical properties of PU nanofibers by an electrospinning technology. The elastic modulus of a single PU nanofiber was measured by an in-situ three-point bending test based on atomic force microscopy (AFM). In addition, the electrochemical properties of the electrospun TiO2-modified PU nanofiber as separators for Li-ion batteries were studied. The results indicate that the mechanical properties of the TiO2 modified PU nanofibers have been enhanced by the ultrafine TiO2 nanoparticles. The TiO2 modified PU separators show good rate capability and cycling performance in Li-ion batteries compared with the raw ones.
