| Popis: | This review is focused on synthetic, natural and semi-natural polyampholytes and their ability to form interpolymer complexes with other polyelectrolytes and non-ionic polymers. It provides definition, classifica-tion and overview of physicochemical properties of polyampholytes. The conformation and phase behaviour of intrinsically disordered proteins and semi-natural polyampholytes derived from aminoacids is discussed. The ability of synthetic, natural and semi-natural polyampholytes to form interpolymer complexes with wa-ter-soluble polymers is considered. Most of the research in this area is focused on interpolyelectrolyte com-plexes of polyampholytes with oppositely charged polyelectrolytes; however, there are also studies demon-strating the formation of hydrogen-bonded complexes. The nature of the complexation is often affected by so-lution pH and also isoelectric point of polyampholytes. The complexation between polyampholytes and other polymers may lead to formation of colloidal dispersions (nano- and microparticles), liquid-liquid phase sepa-ration (called complex coacervation), fully soluble polycomplexes or physically cross-linked gels. A substan-tial body of studies in this area was focused on the complexes formed by proteins. Application of interpolymer complexes formed by polyampholytes in biotechnology, medicine, encapsulation technologies, separation science, biocatalysis, food science and pharmaceutics is discussed. |
