芘从H_2O/DMF混合溶剂向聚苯乙烯/聚丙烯酸二嵌段共聚物平头胶团增溶(Ⅱ)

摘要: 混合溶剂水含量强烈影响芘从Ｈ２Ｏ／ＤＭＦ混合溶剂向聚苯乙烯／聚丙烯酸二嵌段共聚物平头胶团的增溶，随着水含量增加而明显增大了芘和胶团内核ＰＳ间的结合力，促进了芘的增溶。实验结果表明，增加混合溶剂极性组分是实现有效增溶的一种简便方法。

Abstract: The effects of water content in the solvent mixture (W H 2O ) on solubilization of pyrene (Py) from H 2O/DMF solvent mixture into the "crew cut" micelles of polystyrene b polyacrylic acid (PS b PAA) diblock copolymer have been examined. The re
