Abstract:

This research aims to improve the mechanical properties of polyacrylonitrile/polyurethane(PAN/PU)nanofiber transparent membrane. During electrospinning, rotating drum was used as collector. Transparent PU film reinforced by PAN nanofibers (PANNFs/PU film)were prepared by following heating treatment. The morphology,structure and mechanical properties of the films were characterized by scanning electron microscope, infrared spectrometer, multifunctional stretcher. The results show that the fiber arrangement in PAN/PU films along the drum rotating direction becomes obvious with the increase of drum rotating speed. The mechanical properties of PANNFs/PU film are improved significantly through heat treatment. When the rotating speed is 1 500 r/min, the breaking stress of the PAN/PU membrane along the drum rotating direction is 103.3 MPa, and that of the PANNFs-PU film along the drum rotating direction reaches 306.8 MPa coupled with a high breaking strain of 163.1%. Compared with PAN/PU porous membrane, the mechanical properties of PANNFs/PU transparent membrane are significantly improved.
