摘要：

In order to prepare polylactic acid (PLA) hollow fiber membranes with high strength and high separation precision, homogenous and heterogeneous braided tube reinforced PLA hollow fiber membranes were prepared by concentric circular spinning technique. The influences of polyethylene glycol (PEG) molecular weight on the structure and properties of the homogenous reinforced membranes were investigated. Moreover, the influences of homogenous and heterogeneous braided tubes on the interfacial bonding properties were also studied by physically back washing and ultrasonically water bathing shaking. The results show that with the increase of the PEG molecular weight, the surface pores size of the membranes decreases. In addition, the permeate flux of the membranes increases firstly and then decreases, and the bovine serum albumin rejection ratio increases first and then stabilizes with the increase of the PEG molecular weight. It is also found that the interface adhesion between homogeneous braid tube and PLA hollow fiber membranes are better than the heterogeneous ones.
