| Abstract: | Nano-silica was treated with vinyl-silane A-151,which had a good hydrophobicity;on the other hand,it is advantageous that byproduct is harmless to equipments and environment.The surface status of nano-silica before and after modification were studied.It was verified that modification of nano-silica can be carried out by this technics and the aggregation of nano-silica can be dispersed effectively.The analysis of FTIR proved that the A-151 had been successfully grafted on the surface of nanosilica. |
