摘要: Deviations from bulk morphologies in thin films of binary blends alkyne-functionalized diblock copolymer poly(ethylene oxide)-block-poly(n-butyl methacrylate-random-propargyl methacrylate) (PEO-b-P(nBMA-r-PgMA)) and Rhodamine B azide are reported, where thermal click reaction between the two components leads to microphase separated morphologies. Both films, increasing loading ratio resulted transition a lamellar microdomain morphology hexagonally packed cylindrical mircodomain morphology. However, lamellae-cylinder was observed at different ratio, which determined by film thickness. As result, significant deviations were observed. These results indicate that surface interactions confined geometry can play an important role dictating BCP/additive blends.
