| 摘 要： | 采用乳液聚合法,以BA、MMA为主链结构,GMA为官能单体,合成出具有活性结构的丙烯酸酯核-壳纳米粒子。采用透射电镜观察合成的粒子为纳米级核-壳结构。通过红外光谱进行结构分析,表明所合成的纳米粒子具有典型特征吸收峰,表明得到的产物为目标产物。研究了丙烯酸酯乳液聚合参数对乳液的影响,确定了使丙烯酸酯乳液综合性能较好最佳聚合体系;通过TEM观察产物中粒子的结构形态及大小,即得到的丙烯酸酯乳液中,乳胶粒呈明显的核-壳结构,且粒径为纳米级。

| Abstract: | Core-shell nanoparticles with active structure were synthesizedby emulsion polymerization method. BA and MMA were employed to form the main chain structure and GMA was used as functional monomer. The nanoparticles＇ micro-structures were observed by TEM, and the typical characteristic absorption peaks were shown by IR. The factors which had effects on ac~late emulsion polymerization were analyzed, and the optimal polymerization system was confirmed. Then a stable emulsion possessed excellent properties was received. The particles＇ structure morphology and size were observed by TEM, and the nano-particles with core-shell structure were obtained. |
