摘要
本文采用氧化石墨烯(GO)和1,1-二苯乙烯封头水解聚甲基丙烯酸缩水甘油酯(PGMA_(m))共存的协同稳定体系通过界面聚合法制备了以环境友好型防污剂——DCOIT为芯材的DCOIT@PGMA_(m)/GO微胶囊。采用光学显微镜(OM)对微胶囊的形貌进行表征。通过FTIR图谱和NMR图谱证明了DCOIT的成功包覆,借助XRD图谱和拉曼光谱证明了微胶囊外层壳中GO的存在。通过紫外分光光度计对微胶囊的缓释性能进行了研究,结果表明在溶剂环境下微胶囊连续释放10天其释放率仅为61%。所以该微胶囊可以保证芯材的长久释放周期,在海洋防污、水产养殖等领域具有广阔的应用前景。
In this paper,DCOIT@PGMA_(m)/GO microcapsules with environmental friendly antifouling agent DCOIT as core material were prepared by interfacial polymerization using a cooperative stable system of graphene oxide(GO)and 1,1-stilstyrene head hydrolyzed polyglycyl methacrylate(PGMA_(m)).The microcapsules were characterized by optical microscopy(OM).The successful coating of DCOIT was demonstrated by FTIR and NMR spectra,and the existence of GO in the outer shell of the microcapsules was demonstrated by XRD spectra and Raman spectroscopy.The slow-release properties of microcapsules were studied by ultraviolet spectrophotometer.The results showed that the release rate of microcapsules was only 61%after 10 days of continuous release in solvent environment.Therefore,the microcapsule can ensure the long release cycle of the core material,and has broad application prospects in the fields of Marine pollution prevention and aquaculture.
