Our aim here is to predict elongational flow-induced enhancements in thermal or electrical conductivity of liquid crystal polymer LCP nano-composites. To do so, we combine two classical mathematical asymptotic analyses slender longwave hydro-thermo-dynamics for fibers and exact analysis of pure elongation of LCPs in solvents for bulk phases without boundary effects and homogenization theory for effective properties of low volume-fraction spheroidal inclusions. Two implications follow elongational flow dominates fiber free surface and thermal effects on electrical and thermal conductivity enhancements and, there appears to be no sacrifice in enhancements by producing much higher radius, bulk fibers.
