conclusionThe fineness of grain is more and more easily reunite.It is not easy to be distributed evenly in organic medium, and the combination of the base material is poor.It is very easy to cause the interface defect, and the material performance is decreased.The particles are not easy to reunite, and they are so dispersed that they can form a strong bond and bond with organic materials.
