摘要

Abstract

Deviations from bulk morphologies in thin films of binary blends of alkyne-functionalized diblock copolymer poly(ethylene oxide)-

block

-poly(

-butyl methacrylate-

random

-propargyl methacrylate) (PEO-

-P(

BMA-

-PgMA)) and Rhodamine B azide are reported

where thermal click reaction between the two components leads to microphase separated morphologies. Both in the bulk and in thin films

increasing the azide loading ratio resulted in the transition from a lamellar microdomain morphology to a hexagonally packed cylindrical mircodomain morphology. However

in thin films the lamellae-cylinder transition was observed at a different azide loading ratio

which was determined by film thickness. As a result

significant deviations from the bulk morphology were observed. These results indicate that surface interactions and confined geometry can play an important role in dictating the morphology in thin films of BCP/additive binary blends.
