The hydrophobic association of fluorocarbon-modified polyacrylamide aqueous solutions has been investigated on a mesoscopic level by considering the variation of root mean square (RMS) end-to-end distances using dissipative particle dynamics (DPD) simulation. Its hydrophobic association property is affected by the type of the hydrophobic group, salt, temperature and shear. The unit of stronger hydrophobic property within the chain makes the macromolecule have the greatest association in the solution.
