Advances in hydrogen-bonded polymer complexes: nanoparticles, multilayers and microcapsules



报告人:Prof. Vitaliy Khutoryanskiy,英国雷丁大学(University of Reading)药学院教授。


Water-soluble non-ionic polymers are able to interactwith poly(carboxylic acids) and form interpolymer complexes (IPCs) in solutions and their self-assembly process is driven by cooperative hydrogen bonding [1]. The structure of IPCs is dependent on the nature of polymers and solvent, their concentration in solutions, pH and ionic environment, temperature and some other factors. In this lecture the results of our recent studies into the complexation of poly(acrylic acid) with various non-ionic polymers will be presented and following aspects will be covered: (1) Effect of solution pH and solvent nature on the structure of self-assembly [2, 3]; (2) Thermodynamics of complexation studied by isothermal titration calorimetry [2]; (3) Formation of IPCs at solid surfaces using layer-by-layer deposition approach [2-5]; (4) Complexes formed between poly(acrylic acid) and PEGylatedorganosilica nanoparticles [6]; (5) Formation of hollow microcapsules at liquid interfaces [7].
