A nanoparticle-induced phase transition in a block-copolymer thin film and the formation of different structures of gold nanoparticles were investigated. The transmission electron microscopy show the cross-sectional morphology of the film from toluene. The variation in morphology and concentration of gold particles was observed in solvent. The results show that the observed morphological changes and a layered order-order transition in block copolymer films were caused by introducing high concentrations of surface modified gold nanoparticles into one of the diblock domains.
