I sistemi organici organizzati supramolecolarmente rappresentano uno strumento moderno nello sviluppo di nuovi materiali per applicazioni tecnologiche avanzate. Sfruttando peculiari interazioni in grado di promuovere processi di self-assemply, sono stati recentemente osservati in materiali polimerici interessanti ed importanti effetti sulle proprietà reologiche e viscoelastiche e/o sulla capacità di self-healing. L'attività di ricerca si è focalizzata sulla progettazione, sintesi e studio di composti organici contenenti sia unità capaci di self-assembly che specie reattive attivate termicamente da impiegare nella modifica delle proprietà meccaniche ed elastomeriche di polimeri di potenziale interesse per applicazioni nel settore degli pneumatici. Le specie reattive attivate termicamente hanno dimostrato di reagire con opportune funzionalità presenti nella matrice polimerica mentre le unità capaci di self-assembly sono state sfruttate per introdurre interazioni intra e inter catena polimerica con lo scopo di modulare parametri reologici e viscoelastici importanti nella definizione delle proprietà meccaniche della matrice polimerica.

Abstract
Supramolecularly arranged organic systems are a modern tool in the development of new materials for advanced technological applications. Exploiting peculiar interactions able to promote self-assembling processes, interesting and important effects on rheological and viscoelastic properties and/or on self-healing capability were recently observed in polymeric materials. The research activity has focused on the design, synthesis and study of organic compounds bearing both self-assembling units and thermally activated reactive species to be employed in the modification of mechanical and elastomeric properties of polymers of potential interest in tyre applications. The thermally activated reactive species have been shown to react with suitable functionalities present in the polymeric matrix while the self-assembling units have been exploited to introduce intra and inter-polymeric chain interactions with the aim of modulating rheological and viscoelastic parameters important in defining the mechanical properties of the polymeric material.File | Dimensione | Formato | |
