| 英文摘要 | A simple approach was used to control the large-scale wettability of polymer-coated surfaces merely by adding micro-amounts of selective solvents of different polarity to tri-block copolymer solutions. an amphiphilic tri-block copolymer, poly (ethylene oxide) -poly (dimethylsiloxane) -poly (ethylene oxide) (peo-pdms-peo), was used to form micelles and reverse micelles by adding micro-amounts of a selective solvent to the initial solution. the micellar and reverse micellar film coatings show different wettability from hydrophilic to hydrophobic, and even from superhydrophilic to superhydrophobic when micro-scale roughness is involved. the structures of the micelles and reverse micelles were studied by transmission electron microscopy and atomic force microscopy, and the surface chemical composition of the film coatings was determined by x-ray photoelectron spectroscopy (xps). the results reveal that the main cause of differences in wettability is the different surface chemical compositions induced by the different structures of micelles and reverse micelles. |
