摘要: In this study, critical micelle concentration (cmc) was determined for polybutadiene-block-poly (ethyleneoxide), PB (1800)-b-PEO (4000) amphiphilic diblock copolymer in aqueous media by fluorescence spectroscopy and dynamic light scattering (DLS) techniques. The fluorescence measurements were performed by using pyrene as a probe molecule in order to determine the cmc while the intensity of the scattered light from solutions was analyzed with the DLS technique. The cmc values determined by these two techniques for PB (1800) …
