Nanocellulose (NC) composite membranes containing novel ternary materials including NC, imidazole (Im), and mesoporous phosphotungstic acid (-PTA) were successfully fabricated by a phase inversion method. The single-particle size of NC was 88.79 nm with a spherical form. A -PTA filler with a mesopore size of 4.89 nm was also successfully synthesized by a self-assembly method. Moreover, the fabricated membrane NC/Im/-PTA-5 exhibited the best performances towards its proton conductivity and methanol permeability at 31.88 mS cm and 1.74 × 10 cm s, respectively. The membrane selectivity was 1.83 × 10 S cm.
通过相转化法成功制备了包含新型三元材料（纳米纤维素（NC）、咪唑（Im）和介孔磷钨酸（-PTA））的纳米纤维素复合膜。NC的单颗粒尺寸为88.79nm，呈球形。还通过自组装法成功合成了介孔尺寸为4.89nm的-PTA填料。此外，制备的膜NC/Im/-PTA-5在质子传导率和甲醇渗透率方面表现最佳，分别为31.88mS/cm和1.74×10cm/s。膜的选择性为1.83×10S/cm。
