Hybrid material combines organic-inorganic substituents that can impose hydrophilicity and anti-biofouling properties in polymeric membranes. In this study, ginger extract-silica nanoparticles (GE-SiNPs) hybrid materials were synthesized through the sol-gel technique and was applied as a new additive to improve polyvinylidene fluoride (PVDF) membrane properties. Ginger (Zingiber officinale Roscoe) extract (GE) contains phenol derivatives that provide anti-microbial properties; while silica nanoparticles (SiNPs) plays role to increase membrane hydrophilicity and prevent organic fouling. The PVDF/GE-SiNPs membrane was prepared using non-solvent induced phase separation method and was applied to concentrate Bovine Serum Albumin (BSA). The resulted membranes were characterized in terms of morphology, hydrophilicity, tensile strength, porosity, pure water flux, antibacterial property, and its ultrafiltration performance on BSA concentration. The result analysis of fabricated membrane revealed that increasing the loading amount of GE-SiNPs improved membrane hydrophilicity and enlarged membrane porosity. Water permeability was enhanced up to 9.89 from 4.97 LMH. The highest rejection of BSA solution reached of 68.19 %, with the BSA initial concentration of 50 ppm and trans membrane pressure of 1 bar. The flux recovery ratio (FRR) was satistifically reached of 97.92 %. Furthermore, the PVDF/GE-SiNPs also showed antibacterial properties against Escherichia coli and Staphylococcus aureus.

混合材料结合了有机-无机取代基，可以在聚合物膜中施加亲水性和抗生物污染特性。在这项研究中，姜提取物-二氧化硅纳米粒子（GE-SiNPs）杂化材料通过溶胶-凝胶技术合成，并作为一种新的添加剂来改善聚偏二氟乙烯（PVDF）膜的性能。生姜 ( Zingiber officinale Roscoe) 提取物 (GE) 含有具有抗微生物特性的苯酚衍生物；而二氧化硅纳米粒子（SiNPs）则起到增加膜亲水性和防止有机污染的作用。PVDF/GE-SiNPs 膜采用非溶剂诱导相分离方法制备，并用于浓缩牛血清白蛋白 (BSA)。对所得膜的形态、亲水性、拉伸强度、孔隙率、纯水通量、抗菌性能及其对 BSA 浓度的超滤性能进行了表征。制备的膜的结果分析表明，增加 GE-SiNPs 的负载量提高了膜的亲水性并扩大了膜的孔隙率。透水性从 4.97 LMH 提高到 9.89。BSA 溶液的最高去除率达到 68.19%，BSA 初始浓度为 50 ppm，跨膜压力为 1 bar。焊剂回收率（FRR）令人满意地达到了 97.92%。此外，PVDF/GE-SiNPs 还表现出对大肠杆菌和金黄色葡萄球菌。
