| Abstract: |
| A novel paper-based ultrafiltration (UF) composite membrane was developed via paper coating technology. This composite membrane was obtained by coating PVA with glutaraldehyde as crosslinking agent on the surface of the paper sheet which was employed as the support layer. The paper sheet with a base weight of 50 g/m2 was used in this study, and the paper sheet was prepared using the furnish with 80°SR beating degree. The resulting membrane performed with satisfied results when the concentrations of PVA and glutaraldehyde were 0.5% and 1.0%, the crosslinking reaction was conducted at 60℃ for 5 min, and the sample was dried at 20℃, respectively. The results showed that the diameters of the pore of the membrane are 30~100 nm, and the membrane has the properties of high retention performance, good mechanical strength, temperature & alkali resistant properties and antifouling ability. |
