摘要
以改性微晶纤维素(MCC)和壳聚糖(CS)为原材料,通过添加十二烷基磺酸钠(SDS)和新戊二醇二缩水甘油醚(NGDE)制备了一种新型泡沫吸水材料。利用SEM、FT-IR、XRD和BET对吸水材料的结构进行表征。结果表明,当SDS质量分数为4%、NGDE质量分数为4%时,其吸水效果最高,能够吸收120 g/g去离子水,在盐水中能够达到62 g/g,具有良好的保水性能和再膨胀性能。
Abstract
Using modified microcrystalline cellulose (MCC) and chitosan (CS) as raw materials,a new type of foam water-absorbing material is prepared by adding sodium dodecyl sulfonate (SDS) and neopentyl glycol diglycidyl ether (NGDE).SEM,FT-IR,XRD and BET are utilized to characterize the structure of the water-absorbing materials.It is shown that the highest water absorption effect can be achieved when the concentrations of SDS and NGDE are 4 wt% and 4 wt%,respectively.The material can absorb 120 g·g-1 of deionized water,and 62 g·g-1 of water from brine,showing a good water retention performance and re-swelling performance.
