| 摘 要： | 以木薯淀粉为原料,丙烯酰胺为单体,N,N-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,采用微波辐射技术辅助制备木薯淀粉基水凝胶。探究单体、交联剂、引发剂用量等因素对水凝胶溶胀性能的影响。当淀粉与丙烯酰胺用量比为1∶3,N,N-亚甲基双丙烯酰胺为0.02 g,过硫酸钾0.05 g时,微波400 W,60 s制得的木薯淀粉水凝胶达最高吸水倍率。通过傅里叶红外光谱仪(fourier transform infrared spectrometer,FTIR)、场发射扫描电子显微镜(field emission scanning electronic microscope,FESEM)等分析测试手段对其进行表征,结果表明已成功制备木薯淀粉基水凝胶。该水凝胶溶胀平衡比在35℃时达到最大,且在室温条件下保水性良好。该研究为淀粉水凝胶的制备应用提供了实验依据,提高了木薯淀粉的附加值。
