Obiettivo This proposal is a collaborative project to formulate molecular, thermodynamic and kinetic criteria for the appearance of columnar mesophases in flexible non-mesogenic macromolecules and to investigate thei stability, structure and morphology of these phases. The roles of intramolecular interactions of side groups in flexible macromolecules and of interchain interactions in the formation of columnar phases will be assessed and a unified set of principles underlying this phenomenon will be established. These principles will be applied to conventional carbon chain polymers in the search for conditions under which they might display similar mesophase behaviour. Various thermodynamic and kinetic aspects of crystal- crystal transitions in polymers forming columnar mesophases will be studied and their role in crystallisation and development of crystalline morphology will be investigated. Peculiarities of defects in 2D crystals and structural reorganisation processes in polymers exhibiting columnar mesophases will be investigated, with particular reference to their high molecular mobility. Specific features of rheological behaviour of the mesophases will be established and considered in relation to high molecular mobility and from the standpoint of a dislocation mechanism of their plasticity. Based on results obtained, various approaches to producing high performance and smart materials will be proposed, e.g. the conditions required for achieving very high degrees of orientation will be formulated.
