Preparation and Slow-release Properties of DCOIT@PGMAm/GO Microcapsules
In this paper,DCOIT@PGMAm/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(PGMAm).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.
