Abstract:
In order to enhance the mechanical properties of electrospun (PET) membranes, the PET/palm fiber-based actived carbon fiber(PET/PACF) composite fibrous membranes were prepared by adding PACF in PET solution, and electrospinning. The effect of the content of PACF on the morphology, crystallization behavior and mechanical properties of the PET/PACF composite fibrous membrane were studied. The results show that the addition of PACF obviously improves the drafting effect of fiber, so that node-like fiber eliminates, the adhesion between fibers reduces and the reduces and the fiber diameter becomes more uniform. The glass transition temperature and crystallinity are increased by 10 ℃ and 6.7% along with the PACF content increasing, respectively. It is indicate that PACF can enhance the drawing effect of the electric field to jet flow to improves the orientation degree. The crystal temperature increases by 13.7 ℃ showing that the heterogeneous nucleation effect of PACF promote the crystallization of fibrous membrane. Aolng with the increasing of the crientation degree, when the PACF content is 2.5%, the tensile strength of the PET/PACF membranes reaches 4.22 MPa, increases by 366.3% compared with pure electrospun PET membrane.
Key words: electrospinning, polyester/palm fiber-based activated carbon composite fibrous membrane, crystallization behavior, mechanical property
