In order to study the aggregation behavior of hydrophobic modification dendrimer in solution, fluorescence probe was used to research the mutual effect between pyrene and hydrophobic associating polymer AP-P4 or dendrimer. The microsturcture of two kinds of polymers in solution was compared through ESEM. The results showed that the amount of hydrophobic micro-domain formed in solution increased with increasing concentration of polymer. When the average capacity of hydrophobic micro-domain solubilizing pyrene molecule reached maximum, the mass concentratioin of AP-P4 and dendrimer was 1300 mg/L and 600 mg/L respectively. The capacity of dendrimer solution sloubilizing pyrene molecule was stronger than that of AP-P4 solution, and the number of hydrophobic micro-domain formed was larger too. While polymer concentraion was more than 870 mg/L, the average capacity of dendrimer solubilizing pyrene molecule was less than that of AP-P4. Comparing the microstructure of dendrimer and AP-P4 through ESEM, there were small network structure stacking, spreading and connecting with each other in three-dimensional network structure formed by dendrimer in solution, which increased the whole microstructure tightness but reduced the hydrophobica micro-domain volume of dendrimer and the average capacity of hydrophobic micro-domain solubilizing pyrene molecule.
