The Hydrophobic Nanoparticles Adsorption Layer on Core Surface and its Properties

Abstract:

A compact hydrophobic nanoparticles (HNPs) adsorption layer，which had miro- and nano- dual structural properties, can be built by adsorption of HNPs on core surfaces, and then the wettability of core surface can be change from hydrophilic into strong hydrophobic. Measurements validated that the maximum contact angle of HNPs adsorption surface was close to 150°. This method has a very good prospect for industrial application. The flow resistance can be significantly reduced when the water flow through the core micro-channel walls adsorbed HNPs. Core displacement experimental results show that the largest drag reduction rate can be up to 159%, and the average to 73.4%. The results have important significance to the studies of the HNPs drag reduction technology.
