摘要:
以偶氮二异丁腈(AIBN)为引发剂，巯基乙胺(AET)为链转移剂，通过自由基聚合合成了氨基封端的香豆素型光敏共聚物NH2-P(VM-co-AMPS)。再以1-(3-二甲氨基丙基)-3-乙基碳二亚胺盐酸盐(EDC)和 N-羟基琥珀酰亚胺(NHS)室温催化大豆蛋白(SPI)上羧基和NH2-P(VM-co-AMPS)端氨基发生酰胺化缩合反应，得到接枝物SPI-g-P(VM-co-AMPS)。用傅里叶红外光谱、1H NMR对接枝物NH2-P(VM-co-AMPS)和SPI-g-P(VM-co-AMPS)进行结构表征。透射电镜、动态激光光散射、紫外可见光光谱、Zeta电位仪对SPI-g-P(VM-co-AMPS)的水溶液行为进行研究，结果显示：SPI-g-P(VM-co-AMPS)在水溶液中形成粒径Rh为105 nm的球形聚集体，该聚集体表现出较好的光响应性。
Abstract:
The amino-terminated photo-sensitive copolymers (NH2-P(VM-co-AMPS)) were first prepared via a free radical polymerization. Then the graft copolymers (SPI-g-P(VM-co-AMPS)) were prepared by a graft reaction between the carboxylic acid groups of soy protein isolate (SPI) and the amino groups of NH2-P(VM-co-AMPS) using 1-(3-(dimethylamino) were characterized by FTIR and 1H NMR. The aqueous solution behavior were studied by transmission electron microscopy(TEM), dynamic light scattering (DLS), UV-vis spectroscopy, zeta potential. The results showed that SPI-g-P(VM-co-AMPS) could self-assemble into the spherical aggregates with the average size (Rh) of 105 nm. UV-vis spectra confirmed that the aggregates was photo-crosslinkable.
