摘要：In recent years, the problem of oily sewage has seriously affected the ecological environment and human health. Thus, we prepared a novel biodegradable poly (lactic acid) (PLA) membrane with antibacterial property and oil-water separation function via electrospinning method. First, the matter of silver ion glass microbeads (AgGB) loaded with layered double hydroxides (LDHs) and the LDH@AgGB modified with 3-triethoxysilyl-1-Propanamine (APTES) were synthesized. Then, the LDH@AgGB were blended with PLA to prepare PLA/LDH@AgGB composite. And the PLA nanofibrous membranes were electrospun. The results showed that APTES could significantly improve the dispersion and compatibility of LDH@AgGB in PLA matrix. The addition of A-LDH@AgGB could greatly improve the crystallinity, and control the porosity and pore-size of PLA membranes. The maximum water contact angle of the PLA membranes could reach to 109.31 degrees, while the oil contact angle of the PLA membranes decreased to 0 degrees resulting in a high oil absorption capacity, and fast oil absorption rate performance. Meanwhile, the PLA membrane had efficient antibacterial property against Escherichia coli. The reported novel LDH@AgGB and its PLA composite membrane provided a method for designing and preparing environmental-friendly, high-performance materials with both excellent antibacterial property and oil-water separation.
