Wettability measurement on QC10SH SAM reveals a hydrophilic surface. RA-IR researches suggests that the SAM has formed highly-organized and closely-packed structure. A method is developed for quanitatively evaluating the molecular orientation in monoayer. By this method the result that the twisting and tilting angles of QC10SH moecule in SAM are 50±4° and 24±3°respectively has been obtained.展开更多

The research showed that as the reaction proceeded, the hydrophobicities and the adhesion forces of the sample surfaces increased gradually. Afer 15 min reaction, the glass surface was completely hydrophobic with an advancing contact angle of 105° and an inteifacial energy of55. 79 mJ m-2.展开更多
