| 英文摘要 | This paper describes the formation of fibril like aggregates from the self-assembly of block copolymer mixture (polystyrene-b-poly(4-vinylpyridine) (PS-b-P4VP) and polystyrene-b-poly(acrylic acid) (PS-b-PAA)) via interpolymer hydrogen bonding in nonselective solvent. The hydrogen bonding between P4VP and PAA in chloroform leads to the formation of complex. When all the pyridine units in P4VP were all hydrogen bonded to acrylic acid in PAA, the formed complex is insoluble, resulting in the formation of spherical micellar aggregates and nanorods. However, two kinds of supramolecules with insoluble or soluble complex are formed in the solution when PS-b-P4VP and PS-b-PAA are mixed with equal mole ratio. The fibril like aggregates can be formed from the self-assembly of supramolecule with soluble complex during spin-coating process. The effects of evaporation rate of solvent and solution concentrations on the formation of fibril like aggregates were investigated. The results prove that the kinetic factors play an important role in the formation of the fibril like aggregates. (C) 2008 Elsevier Ltd. All rights reserved. |
