| 摘 要： | 通过乳液聚合制备了交联聚丙烯腈纳米微球,对其进行碱性水解,得到了含酰胺基等亲水基团的亲水性微球。用动态光散射、红外光谱、透射电镜对水解前后微球的结构、大小和形态进行了表征,发现:水解后,微球中的腈基大多转变为酰胺基或羧基亲水基团,且微球的尺寸大幅增加。

| Abstract: | PAN nanospheres can be modified via transformation of the cyano groups into amide or carboxyl groups by alkaline hydrolysis. In this paper, the cross-linked polyacrylonitrile nanospheres were converted to hydrophilic microspheres via alkaline hydrolysis. FTIR, TEM and dynamic light scattering techniques were used to characterize the PAN nanospheres and the resultant hydrophilic microspheres. |

| Keywords: | polyaerylonitrile alkaline hydrolysis amide group |
