[Abstract]:In this study, the research progress of polyamide-amine, polyglycidyl and polyethyleneimine as metal nanoparticles stabilizers are introduced. Polyamide-amine hyperbranched polymers can be used as water shutoff agents and chemical oil removers. They can be used as both reducing and dispersing agents in metal nanoparticle reactors to stabilize the dispersion of metal nanoparticles. Polyglycidyl, which contains a lot of hydroxyl groups, can be modified to obtain amphiphilic nano-capsules with good biocompatibility and can be used as a high quality demulsifier for crude oil. The particle size of metal nanoparticles can be controlled by their relative molecular weight, and polyvinyleneimide-amine has a large number of amine functional groups, which provides abundant sites for coordination of metal ions, and its encapsulated metal nanoparticles can be used as temperature-sensitive materials. In combination with the structural controllability of hyperbranched polymers and the excellent catalytic performance of nanometallic materials, these materials will have great application prospects in petroleum engineering.
