Abstract

Ultrafiltration membranes in the fields of water treatment and biomedicine should have high permeability as well as antibacterial and antifouling capabilities. In this study, based on the hydrophilicity of fullerol (C(OH)) and the bacteriostatic properties of silver (Ag), a fullerol-silver (C(OH)-Ag) complex was prepared as a multifunctional additive. A polyvinylidene fluoride (PVDF)-composited C(OH)-Ag ultrafiltration membrane (C(OH)-Ag/PVDF) was prepared by immersion precipitation phase transformation. Addition of the C(OH)-Ag complex improved the permeability and retention of the traditional PVDF membrane. Compared with the traditional PVDF membrane, the surface water contact angle of the modified PVDF and C(OH)-Ag ultrafiltration membrane was reduced from 75.05° to 34.50°, its pure water flux increased from 224.11 L·m·h to 804.05 L·m·h, the retention rate on bovine serum protein was increased from 75.00% to 96.44% and the flux recovery rate increased from 64.91% to 79.08%. The C(OH)-Ag/PVDF ultrafiltration membrane had good inhibitory effects on and , while the PVDF ultrafiltration membrane had no obvious inhibitory effects.

摘要

水处理和生物医学领域中的超滤膜应具有高渗透性以及抗菌和抗污染能力。在本研究中，基于富勒醇（C(OH)）的亲水性和银（Ag）的抑菌特性，制备了一种富勒醇-银（C(OH)-Ag）复合物作为多功能添加剂。通过浸没沉淀相转化法制备了聚偏氟乙烯（PVDF）复合C(OH)-Ag超滤膜（C(OH)-Ag/PVDF）。添加C(OH)-Ag复合物提高了传统PVDF膜的渗透性和截留率。与传统PVDF膜相比，改性PVDF和C(OH)-Ag超滤膜的表面水接触角从75.05°降至34.50°，其纯水通量从224.11 L·m⁻²·h⁻¹增加到804.05 L·m⁻²·h⁻¹，对牛血清蛋白的截留率从75.00%提高到96.44%，通量恢复率从64.91%提高到79.08%。C(OH)-Ag/PVDF超滤膜对[此处原文缺失两种细菌名称]具有良好的抑制作用，而PVDF超滤膜则没有明显的抑制作用。
