| 摘 要： | 以丙烯酰胺（AM）为亲水单体，与两种单体（丙烯酸十八酯C18、两性单体二甲基乙酰胺DMAC）、三种表面活性剂（十二烷基硫酸钠SDS、四丁基溴化铵TBAB、十六烷基三甲基溴化铵CTAB）采用自由基溶液聚合法制备得到5种疏水缔合水凝胶，并测量了5种水凝胶对CH4的储气性能及吸水性能。结果表明，两种表面活性剂（TBAB、CTAB）的添加，对水凝胶的储气性能有明显的影响，其中，水凝胶HC⁃SDS/TBAB对CH4的储气性能最好；两种表面活性剂的添加，对水凝胶的溶胀率也存在明显的影响，添加有两种表面活性剂的水凝胶溶胀性能明显低于单一添加SDS的水凝胶溶胀性能。

| Abstract: | Five kinds of hydrophobic association hydrogel are synthesized with the method of free⁃radical solution polymerization, in which the hydrophilic monomer is acrylic amide (AM), hydrophobic monomers are octadecyl acrylate (C18) and dimethyacetamide(DMAC),the surfactants are lauryl sodium sulfate (SDS),tetrabutylammonium bromide (TBAB),cetyl trimethyl ammonium bromide (CTAB).The gas storage performance of CH4 and the water absorption capability for five hydrogels are measured. The experimental data has proven that the addition of TBAB or CTAB has a significant effect on the storage performance of hydrogels, and the best storage performance of CH4 is HC⁃SDS/TBAB. In addition,the addition of TBAB or CTAB has an obvious effect on the swelling ratio of hydrogel, and the swelling ratios of hydrogels with the addition of two kinds of surfactants are obviously lower than the one with the addition of a single surfactant (SDS). |
