Effects of Solvent and Block Copolymer Composition

CHAPTER 6 AZOBENZENE CONTAINING BLOCK COPOLYMER MICELLES 

Strictly speaking, the origin of the observed effect is more complicated than it may appear to be. The difference between the two BCP samples may come not only from the difference in composition of the two blocks, but can also be contributed by the different compositions of the P(tBA-co-AA) blocks, which actuaUy changes the chemical nature of the hydrophilic block. In order to disclose the effect of BCP composition, it would be more straightforward to utilize BCPs that differ only in the relative lengths of the two blocks, such as PAA-fc-PAzoMA
