摘      要：Highly stable and permeable silicone emulsions were prepared by encapsulating N-octyl triethoaysilane microdroplets into micelles of NH_(2)-PDMS/SiO_(2).The conversion of siloxane to sub-1μm emulsions,on one hand,endows the concrete with a highly hydrophobic internal ***,its outside surface maintains relatively high surface energy,which is beneficial for the post-coating of other *** a result,the coated concreted can simultaneously acquire water repellency and low *** utilization of water-dispersed silicone emulsions,on the other hand,is beneficial for the environmental ***,this work offered a green procedure for the comprehensive protection of concrete.
