摘要:
The influence of pH on the properties of polyacryloylacetone (PAA) monolayers at air/water interface was examined by using surface pressure-area isotherm measurement,a new rheological approach and AFM imaging. The isotherms and AFM-imaging detect phase transitions in PAA monolayers and growth of microdomains during compression in the case of pH 6.6 and missing of such kind of structures at pH 9. The rheological study below and above the phase transition shows an existence of a large relaxation time related to the process of formation of microdomains.
