Different ionic liquid (IL)s were added to hydroxypropyl methylcellulose /monosodium phosphate (HPMC/MSP) photophobic film to improve its ductility, and their effects on its multi-scale structures and physical properties were studied. After adding these ILs, smoothness of the fractal structure, tensile strength, modulus of the film did not change obviously, while the crystallinity, the number of holes, and elongation increased, the hole size and T decreased. Compared to films with other ILs, the film with 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]BF) showed the largest elongation and crystallinity, the smallest hole size, the least holes, and highest whiteness. The film with 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) showed the largest water content and the lowest T. The increased elongation proved that all these ILs could improve the ductility of the film, among which, [EMIM]BF had the strongest plasticizing effect.
不同的离子液体（ILs）被添加到羟丙基甲基纤维素/单磷酸二氢钠（HPMC/MSP）光致变色膜中，以提高其延展性，并研究了它们对膜的多尺度结构和物理性能的影响。添加这些 ILs 后，分形结构的平滑度、拉伸强度、膜的模量没有明显变化，而结晶度、孔数和伸长率增加，孔径和 T 降低。与具有其他 ILs 的膜相比，具有 1-丁基-3-甲基咪唑四氟硼酸盐([BMIM]BF)的膜具有最大的伸长率和结晶度、最小的孔径、最少的孔和最高的白度。具有 1-丁基-3-甲基咪唑氯化物([BMIM]Cl)的膜具有最大的含水量和最低的 T。伸长率的增加证明了所有这些 ILs 都可以提高膜的延展性，其中[EMIM]BF 的增塑效果最强。
