摘要：

A study was conducted to introduce an amphiphilic polymer for performing nanoparticle coating and functionalization tasks. The amphiphilic polymer used in the study is based on a poly(maleic anhydride) backbone. It was found that reaction of a fraction of the anhydride rings with alkylamines led to the formation of the hydrophobic side chains that were needed for intercalation with the hydrophobic surfactant layer on the nanoparticle surface. It was also found that alkylamines and organic molecules, with amino terminations can be formed through such reaction. It was observed that by linking some of the remaining anhydride rings with diamine linkers, the polymer molecules around each nanoparticle are interconnected, crosslinking the shell.
