A unique ferroelectric smectic CG phase, in its bi-tilting configurations induced by admixture of the dimeric liquid crystal (LC) 7OBA, serving as an matrix and amide functionalised graphene oxide (AmGO) was presented. Thus, an electrooptically tunable functionalised nanocomposite, indicating bi-tilting state, displayed by two sub-structures, C-Gcl (clinic) and C-Gln (leaning) was created. Using both microtextural and DSC analysis, we studied the thermal and structural features of the functionalised nanocomposite. By endothermal peak asymmetry analysis, we found an intermediate between C-Gcl and C-Gln state.

Abstract
A unique ferroelectric smectic CG phase, in its bi-tilting configurations induced by admixture of the dimeric liquid crystal (LC) 7OBA, serving as an matrix and amide functionalised graphene oxide (AmGO) was presented. Thus, an electrooptically tunable functionalised nanocomposite, indicating bi-tilting state, displayed by two sub-structures, C-Gcl (clinic) and C-Gln (leaning) was created. Using both microtextural and DSC analysis, we studied the thermal and structural features of the functionalised nanocomposite. By endothermal peak asymmetry analysis, we found an intermediate between C-Gcl and C-Gln state. An enhanced degrees of freedom of the LC director was indicated, allowing an increase of the corresponding micropolarisation LC textures able to create surface memorisation and reach information, respectively.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
