| Popis: | The novel radiation and photo-induced cryochemical solid-state synthesis of metal–polymer materials as well as the structure and physico-chemical properties of synthesized materials were described. The synthesis consists of low-temperature co-condensation of metal and monomer vapors followed by low-temperature solid-state polymerization of the co-condensate under irradiation. Depending on metal nature and monomer structure, this process allows to prepare specific metal–polymer systems: polymers containing organometallic units in polymer chains, metal–polymer complexes or stable metal clusters of various sizes trapped physically inside polymer matrix without coordination bonds between metal and polymer. The thermal treatment of synthesized systems leads to the formation of novel nanocomposite metal–polymer materials characterized by specific electric sensor and magnetic properties, catalytic activity and dielectric anomalies, which are discussed in relation to material structure. |
