The literature review revealed that the presence of nano fillers can alter the morphology of TLCP droplets by altering the flow properties of the blend system. However, the question remains unexplored, what is the effect of sheet like nano fillers on in-situ fibrillation behavior of TLCP in the polymer blend system. In this study, we have used the graphene as nano filler in the nylon-6 and TLCP blends. We have also studied the different sequences of mixing process so as to impart the maximum in-situ fibrillation of TLCP in order to achieve the better properties of the blends. Four types of blending techniques we have considered as follows. a. Entire graphene added to nylon-6 and then blended with TLCP b. Entire graphene is added to TLCP and then blended with nylon-6. c. 50% graphene is added to nylon-6 and 50% graphene is added to TLCP and then both master batches were blended together. d. Both virgin polymers were blended together first and then the entire graphene is added to the virgin polymer blend system. All the blends were then characterized rheologically, mechanically and spectroscopically to assess the extent of fibrillation behavior of graphene as well as its preferable location in the phases. The viscosities of TLCP containing blends are affected by two factors like interfacial adhesion and TLCP fiber formation and orientation. The orientation of TLCP fibers along the flow direction can enhance
