摘要：
Acrylic acid functionalized nano graphene oxide (FAGO)/acrylate composite emulsion was prepared by seed emulsion polymerization via using sodium allyl sulfonate (ALS) as polymerizable emulsifier. The structure of GO and FAGO were confirmed by FTIR and XRD, the morphology of GO, FAGO and nano FAGO/acrylate composite emulsions were observed by SEM and TEM. The results show that the carboxyl group on acrylic acid reacts with GO hydroxyl to form ester bond. The edge of FAGO is distorted and has more local folds, the system of irregularities increase significantly compared to GO. And the nano FAGO/acrylate composite latex particles are regularly spherical. The nano particle size potential analyzer test results show that the nano FAGO/acrylate composite emulsion size is uniform, well-disperse. With the increases of the amount of ALS, the particle size of the latex particles gradually decreases, its dispersion index (PDI) first decreases and then increases, the corresponding Zeta potential gradually increases, the viscosity of the emulsion gradually increases, and the water resistance of latex film becomes worse. When the amount of ALS is 0.8wt%, the nano FAGO/acrylate composite emulsion obtains the best overall performance. © 2019, Editorial Office of Acta Materiae Compositae Sinica. All right reserved.
