| 英文摘要 | In this study, the pH and salt effects on the aggregation behaviour of star polymer, with G1 polyamidoamine as the core and poly(propylene oxide)-block-poly(ethylene oxide) as the terminal branches, were investigated. The results from pH and turbidimetric titration experiments showed that with the pH value increasing from 2.0 to 10.0, the solution transforms from transparent to turbid at pKa=5.5 and eventually presents phase separation at the pH value above 7.5. As revealed by dynamic light scattering and transmission electron microscopy measurements, the size of the aggregates of star polymer becomes bigger with the increase in the pH value or in the presence of salt. It was found that the extent of the salt effect on the aggregation behaviour follows the sequence: C6H5COONaNa2SO4 NaCl. [image omitted]. |
