Kurzfassung in Englisch

The dissertation work focuses on the whole route of material development starting from the investigations of properties of the initial (raw) HBPs to their applications. Each research step is given in a separate chapter to enhance attention to various aspects of the aim of the work. Thus, every chapter is started with an introduction. After that, the methods applied and experimental procedure are described. Next part tries to give the comprehensive description of the results obtained. At the end of the chapter, the main points are summarized. The Chapter 1 gives the theoretical description of the main experimental techniques used in this work. In Chapter 2 the chemical (chemical composition, purity, typical structure elements) and physical (glass transition temperature, the temperature of the maximum decomposition, the thermal stability at the high temperatures, molar mass, polydispersity and possible aggregation in solution) properties examined by different techniques of polymer analysis are described. The Chapter 3 is divided into three separate parts: In Chapter 3.1 the description of the formation and modification of inter- and intramolecular hydrogen bonds of hydroxyl terminated HBP is presented to reveal the information of hydroxyl groups re- and/or association due to the high temperatures applied. In Chapter 3.2 the nature of the solid-liquid interface of HBP thin films have been studied by different surface sensitive techniques with respect to further protein adsorption investigations. In Chapter 3.3 the strategy for the fabrication of surface attached carboxyl terminated HBP using "grafting to" technique is developed. The Chapter 4 consists of two parts: The first (theoretic) part outlines the basic principles of protein chemistry, factors influencing on the protein molecule stability in aqueous medium, the mechanism of protein adsorption and forces involved in the adsorption process. In the second part the combination of different in situ techniques was applied to obtain a comprehensive description of complex adsorption processes of protein molecules on different polymer surfaces.
