I want to prepare a polymer composite with GO as filler. When I tried, GO which was initially well-dispersed in the water start to agglomerate when mixed with a polymer. What should be the method, the ratio of GO and polymer and any other reagents needed to get well-diperssed polymer-GO composite. Thanks

You can do surface modification by any silane. it would be helpful when you do mixing the GO particles with resin. usually amino silanes are better. they tries to avoid agglomeration of particles and make useful reactions with matrix.
