摘要：
Temperature dependence of the structure and interaction of starlike PEG-based block copolymer micelles is discussed. The profile of the core and corona, the chain interactions and the structure factor effects as a function of temperature is also studied. It is found that the temperature dependence of the interchain interactions can be determined. It is shown that it is in agreement with the bulk temperature of PEG using the Flory-Huggins random phase approximation (RPA) theory with a realistic average polymer concentration in the corona.
