- Alginate based biopolymer with improved physical and chemical properties after esterification usingpolyvinyl alcohol (PVA) has been studied for possible application as a hemodialysis membrane. Thealginic acid to vinyl alcohol molar ratio was predetermined at 0, 0.1, 0.5 and 1. Mechanical strength,hydrophilicity and Ca2+adsorption of the membrane before and after modification were evaluated. Theobtained PVA-alginate (PVA-Alg) ester membrane was also confirmed using FTIR and SEM. It showsthat the PVA-Alg membrane tensile strength is higher than that of native alginate. The water contactangle of the membrane was found to be around 33–50◦. The Ca2+adsorption capacity tends to decreasewith the increase in molar ratio. Furthermore, the modified PVA-Alg ester membrane achieves betterprotein adsorption and platelet adhesion than the unmodified one. It also exhibits a dialysis perfor-mance of 47.1–50.0% for clearance of urea and 42.2–44.6% for clearance of creatinine, respectively. It isexpected that this PVA-Alg ester may challenge cellulose acetate for potential application as hemodialysismembranes.
