Microstructure formation in polyblends containing liquid crystalline polymers

Mutual influence of the morphology and capillary rheological properties in nylon/glass‐fiber/liquid‐crystalline‐polymer blends

“…The morphology of a dispersed phase is affected by several factors, and the viscosity ratio is regarded as one of the crucial ones 20–27. If the viscosity of the matrix is too low, shear stress cannot be transferred effectively from the matrix to the dispersed phase, and so LCP will break into droplets only and will not be elongated to form fibrils.…”

Morphology evolution of a liquid crystalline polymer confined by highly packed glass beads in polycarbonate

“…Further, it is widely accepted that the elongational flow developed in the entry of the capillary is mainly responsible for the LCP fibrillation during a capillary extrusion [33]. In an in situ hybrid composite containing LCP droplets and filler particles dispersed in a polymer matrix, extra hydrodynamic effects arise from the presence of filler particles and act on the morphology evolution of the LCP phase.…”

Carbon Nanotube-Reinforced Thermotropic Liquid Crystal Polymer Nanocomposites

“…Thermotropic LCPs with high strength and stiffness due to their rigid-rod- like molecules can be preferentially oriented to form fibrils under elongational or shear flow during melt processing, and oriented fibrous structures are developed in the extruded thermotropic LCPs, resulting in self-reinforcing characteristics [6,7,8]. For this reason, thermotropic LCPs have received considerable attention both in the neat state and as reinforcing fillers for thermoplastic polymers, and much research has been performed to date both to displace conventional thermoplastic polymers and to develop commercial applications of the thermotropic LCPs and their composites such a high performance engineering plastics or fibers [9,10,11,12].…”
