英文摘要: Well-defined alpha-fluorinated alkyl ester, omega-carboxyl telechelic polystyrenes (PS) were synthesized via combining aminolysis of RAFT-polystyrene and thiol-ene "click" reaction simultaneously. The perfluoroalkyl end groups were -CF3, -(CF2)(2)-CF3 and -(CF2)(7)-CF3, respectively. Highly ordered porous films of such telechelic PS with an average pore size about 1.00 mu m were fabricated via a static breath-figure process. With the content of fluorine on the surface of porous films increasing from 1.04 wt%, to 1.64 wt% and 2.97 wt%, respectively, the water contact angle (WCA) of such porous films increased from 112 degrees to 116 degrees and 121 degrees +/- 0.4 degrees, respectively, indicating their hydrophobicity. Interestingly, microspheres with average diameters of ca. 0.30-0.65 mm can be fabricated via a static BF process using methanol instead of water as the vapor atmosphere in the glass vessel.
