Sono stati preparati e caratterizzati nanocompositi a memoria di forma, la cui matrice polimerica consta di un elastomero liquido cristallino (LCE) a base epossidica. Nanotubi di carbonio a parete multipla (MWCNT) e nanoparticelle di grafite (GNP) sono stati selezionati come nanofiller. È stata, quindi, valutata l'influenza di diversi contenuti di nanofiller su proprietà meccaniche, termiche e di memoria di forma. Per disperdere e distribuire omogeneamente i nanofiller all'interno della matrice polimerica è stata effettuata una valutazione approfondita delle condizioni ottimali di realizzazione dei prodotti. Tali condizioni hanno influenzato il grado di distribuzione finale dei nanofiller all'interno della matrice a base epossidica. Infine, i prodotti, sono stati analizzata dal punto di vista macroscopico e microscopico, nonché dal punto di vista chimico, termico e strutturale.
Shape memory nanocomposites were prepared and characterized. The polymer matrix consisted in an epoxy-based liquid crystalline elastomer (LCE). Multi-walled carbon nanotubes (MWCNT) and graphite nanoplatelets (GNP) were selected as fillers. The influence of different contents of nanofillers on mechanical, thermal and shape memory properties was evaluated. In order to disperse and homogeneously distribute the nanofillers within the polymer matrix an in-depth evaluation of the optimal conditions to synthesize the materials was carried out. These conditions had a substantial influence on the final distribution of the nanofillers within the epoxy-based matrix, which was analyzed from a macroscopic and microscopic point of view.

In order to disperse and homogeneously distribute the nanofillers within the polymer matrix an in-depth evaluation of the optimal conditions to synthesize the materials was carried out. These conditions had a substantial influence on the final distribution of the nanofillers within the epoxy-based matrix, which was analyzed from a macroscopic and microscopic point of view.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
