摘要: Composite membranes for dialysis were prepared by a Loeb-Sourirajan (L-S) phase inversion process. After adding nanocrystalline cellulose (NCC), the ultrafiltration coefficient of membrane could reach 48.37 L•m-2•h-1•mmHg-1. The clearance lysozyme and urea 70.25 % 90.38 %, respectively. Simultaneously, retention ratio BSA remain over 96%. Afterwards, in order to judge hydrophilic nature membrane, contact angle surface energy tested calculated. And then tensile strength elongation measured reflect mechanical properties. also observed with transmission electron microscopy (TEM) atomic force (AFM) reveal state dispersion dimensions NCC. porous structures researched both scanning (SEM) AFM.
