Abstract: Amphiphilic polymers have a wide range of applications in biomedicine and nanotechnology because of their unique structures with both hydrophilic chains and hydrophobic chains. Research progress of aggregates formed by molecular self-assembly of amphiphilic polymers is introduced. Some molecular self-assembled aggregates,such as aggregates controlled by structure,composition and molecular weight,semi-crystalline aggregates,crosslinked aggregates,smart aggregates with stimuli-responsiveness (such as pH,temperature,pH/temperature,redox,solvent polarity) are discussed. Research efforts have been focused on controllability of amphiphilic polymers structure and enhancement of stability of aggregates. Crystallization induced molecular self-assembly and smart molecular self-assembly are future research trends.

Key words: amphiphilic polymers, molecular self-assembly, aggregation, nanoparticles, morphology
