摘要
Abstract
Polyacrylonitrile/polyurethane (PAN/PU) composite nanofiber film was prepared by electrospinning. Then polyurethane-based composite film reinforced with polyacrylonitrile nanofiber (PANNFs/PU) was prepared by heating PAN/PU nanofibrous film. The morphological structure of PAN/PU film before and after heat treatment was analyzed by scanning electron microscope (SEM). The mechanical properties of films were tested by multi-function stretcher. The results showed that the mechanical properties of PANNFs/PU film were influenced by the one occupying a large ratio in the electrospun solution. When the mass ratio of PAN and PU in the electrospun solution was 4:6, the breaking stress of prepared PANNFs/PU film reached 152.1 MPa, and the breaking elongation reached 178.8％. Compared with other mass ratio, PANNFs/PU composite film showed the better overall mechanical properties under the mass ratio of 4∶6. When the quality ratio was 4∶6 and the mass fraction of electrospun solution increased to 18％, the breaking stress of PANNFs/PU composite film increased by about 3 times (up to 217.8 MPa) and the breaking elongation increased by about 2.5 times (up to 320.9％) compared with PAN/PU composite nanofiber film.关键词
