Fig. 4. Separation performance and possible separation mechanism of PLA-based membranes.
(A) Separation performance of PLA-based membranes for n-octane–in–water emulsions. (B) Emulsion particle size distribution before and after filtration. (C) The stability of H-PLA-AS nanofiber membranes (the initial permeation is set as 100%). (D) The possible mechanism of the improvement in permeance of H-PLA-AS membranes.
