Abstract:

The supramolecular composite systems of amphiphilic polymers based on electrostatic interactions in recent years have been reviewed, which mainly include the mixtures of different amphiphilic polymers with opposite charges, the mixtures of ionic amphiphilic polymers and organic acids, and the mixtures of amphiphilic polymers and ionic surfactants. Based on the difference of raw materials, the synthesis mechanism and advantages of the supramolecular systems are introduced. The remarkable effects of electrostatic interactions in solving problems in the actual production process of oil field are also summarized, such as applications in oil displacement, profile control and oil-bearing wastewater treatment.

Key words: amphiphilic polymer, electrostatic interaction, organic acid, surfactant, application
