Influence of 2D Layered Nanomaterials on the Piezoelectric Properties of Polymer Based Nanocomposites

The PhD thesis has dealt with the piezoelectric behaviour of 2D nanomaterials based PVDF  nanocomposites.  Unmodified  and  modified  2D  nanomaterials  (graphene  oxide, expanded graphite and hexagonal boron nitride) were incorporated in PVDF matrix and their role  in  enhancing  the  dielectric  and  piezoelectric  properties  of  PVDF  has  been  explored.  A comprehensive  investigation  on  the  influence  of  processing  techniques  on  the  morphology, structure  and  piezoelectric  properties  of  PVDF  based  nanocomposites  has  been  carried  out. Furthermore, UHMWPE based nanocomposites have been studied for the first time for their ferroelectric  and  piezoelectric  behaviour.  A  systematic  interrelation  has  been  successfully developed between processing, structure and property.
