| 英文摘要 | The positron lifetime technique has been used to study the temperature behavior of micelle in solution of polystyrene-polydimethylsiloxane diblock copolymer in n-heptane. The results indicate that positron annihilation parameters are found to be sensitive to structural and microphase changes taking place in the micellar solutions. The abrupt changes in the o-P-H. lifetime and intensity observed at certain temperature appear to be associated with variations in the aggregation state of the copolymer molecules in solutions. Above the critical micelle temperature the o-P-s lifetime increases sharply with increasing temperature. This behavior indicates the process of disintegration of molecular aggregtes to free copolymer molecules. |
