反相(W/O)或双连续相微乳液聚合制备多孔材料是近年研究的热点.研究了双连续相微乳液聚合制备多孔吸油材料:以甲基丙烯酸甲酯、甲基丙烯酸丁酯为共聚单体(油相),水/乙醇为混合水相,偶氮二异丁腈为引发剂,十二烷基硫酸钠为乳化剂,调节油相和水相比例,配制出双连续相微乳液.聚合在无搅拌下进行.对聚合物进行SEM观测表明,当混合水相含量在30%~43%(质量分数,下同)区域内,得到连续开孔材料.仅对多孔材料制备工艺进行研究分析及孔特性进行了表征,吸油材料的研究将在后续文章中报道.
The preparation of porous materials by Inverse microemulsion (W/O) or bicontinuous microemulsion has been an attractive research.This task makes an study on porous oil absorption material from microemulsion polymerization:methyl methacrylate and butyl methacrylate were in the presence of comonomer (oil phrase) while sodium dodecyl sulfate and n-butanol formed a emulsification system,ethanol was dispersed in the water to form a mixture aqueous with azobisisobutyronitrile as an initiator and adjust the proportion between oil phase and water to prepare biocontinuous microemulsion.The polymerization was conducted without stirring.The SEM indicates that continuous porous materials will be observed if the content of mixture aqueous is between 30% to 43wt%.The paper only makes an introduction on the preparation process and the characterization of porous material.
