- Аннотация: Amphiphilic homopolymers, composed of identical amphiphilic monomer units holdinggroups with significantly different affinity to solvent, acquire the properties of polymersurfactants and their ability to self-organization. Grafted to plane solid surface,amphiphilic homopolymers self-assemble to different structures depending on the solventselectivity, monomer surface activity, macromolecular degree polymerization, andgrafting density. The sparsely grafted amphiphilic homopolymers are capable of formingultrathin micelles with a thickness of approximately twice the size of the monomer unit.At high grafting density, the macromolecules self-assemble into lamellae, which areperpendicular to the grafting surface and depending on the solvent quality have twodifferent (small or large) domain spacing. In the transition region the lamellae withdifferent domain spacing form bicontinuos parking garage structure: parts ofmacromolecules, nearest to the grafting surface, form lamellae with small domainspacing, and the upper parts of macromolecules join into lamellae with large domainspacing. The lamellae are turned with respect to each other and are connected by twistedbridges similar to different stores in multistory parking. We not only analyzed theconditions necessary for the self-organization of amphiphilic layers to various structures,but also identified methods for their rapid and effective restructuring.
