Herein, a novel ceramic tubular supported graphene-polydimethylsiloxane nanocomposite (CT/Gr-PDMS) membranes were fabricated via dip-coating method with various graphene contents (0–0.5 wt%) using tetraethylorthosilicate as the crosslinking agent. The characterizations of graphene-polydimethylsiloxane nanocomposite (Gr-PDMS) were analyzed by Fourier-transform infrared spectroscopy, X-ray diffraction spectroscopy, Raman spectroscopy, differential scanning calorimetry, thermogravimetric analysis, scanning electron microscopy, and transmission electron microscopy. The CT/Gr-PDMS membranes were used to separate the furfural-water mixture via pervaporation (PV) technology. The effects of operating conditions, such as feed concentration, feed temperature, and operation time on the PV performance of CT/0.2Gr-PDMS membrane, which were investigated via a one-factor-at-a-time approach. The PV performance of CT/0.2Gr-PDMS membrane revealed permeate flux (J) of 0.63 kg/m²h, separation factor ($\mathrm{\alpha }$) of 85.65, and PV separation index (PSI) of 53.7 kg/m²h in the appropriate operating condition as feed concentration of 2 wt% at 50 °C for 5 h. Moreover, this work has shown the promising potential of the CT/0.2Gr-PDMS membrane in providing PV technology with a high furfural separation performance.

在此，使用原硅酸四乙酯作为交联剂，通过浸涂法制备了一种新型陶瓷管支撑的石墨烯-聚二甲基硅氧烷纳米复合材料（CT/Gr-PDMS）膜，该膜具有不同的石墨烯含量（0-0.5 wt%）。通过傅里叶变换红外光谱、X射线衍射光谱、拉曼光谱、差示扫描量热法、热重分析、扫描电子显微镜和透射电子显微镜分析了石墨烯-聚二甲基硅氧烷纳米复合材料（Gr-PDMS）的表征。CT/Gr-PDMS 膜用于通过全蒸发 (PV) 技术分离糠醛-水混合物。进料浓度、进料温度和操作时间等操作条件对 CT/0.2Gr-PDMS 膜 PV 性能的影响，通过一次一个因素的方法进行调查。CT/0.2Gr-PDMS 膜的 PV 性能显示渗透通量 (J) 为 0.63 kg/m² h，分离系数（$\mathrm{\alpha }$) 为 85.65，PV 分离指数 (PSI) 为 53.7 kg/m ² h，在适当的操作条件下，进料浓度为 2 wt%，在 50 °C 下持续 5 h。此外，这项工作显示了 CT/0.2Gr-PDMS 膜在提供具有高糠醛分离性能的光伏技术方面的巨大潜力。
