제목 Synthesis of Polystyrene and Poly(4-hydroxystyrene)-containing Bottlebrush Block Copolymers Featuring Structural Coloration
초록 Self-assembly of block copolymers (BCPs) has recently received attention as a promising application for photonic crystals due to simple fabrication processes and vivid structural coloration. To generate bright structure colour in visible range, BCPs with high molecular weights (MWs > 400 kDa) and narrow dispersity are typically used in one-dimensional photonic crystals (1D PhCs). However, the applicability of such BCP is hindered by difficult synthesis and chain-entanglement during self-assembly. Thus, bottlebrush block copolymers, which feature less chain entanglement and ultrahigh MWs, can provide better opportunity to create 1D PhCs. In this work, we present the facile synthesis of bottlebrush block copolymers (BBCPs) including polystyrene and poly(4-hydroxystyrene) via ‘grafting-through polymerization’ and acid-catalysed hydrolysis. Additionally, 1D PhC films were fabricated by their self-assembly and controlled by blending with hydrogen-bond accepting organic additives.
