The rheology and structure of thermotropic liquid crystalline polymers in extensional flow
The transient shear and elongational flow behavior of HPC EF, G, and HBA/HNA (Vectra A900) have been measured in order to determine the behavior of liquid crystalline polymer systems and to establish whether this behavior is different from that for isotropic flexible-chain polymer melts and …

Experimental Investigation of Jet Breakup at Low Weber Number
… Weber number. The effects of surface tension and viscosity were investigated by using two viscous liquids (ethylene glycol and propylene glycol) apart from water. Nozzle diameters from 0.279 mm to 1.753 mm were used to study its influence on the liquid jet breakup. </p><p>Results show that the jet …

Experimental and modeling investigation of cellulose nanocrystals polymer composite fibers
… that perfectly collimated CNCs increased the elongational viscosity of the system, thus resulting in a thicker fiber. ^ The methods and results presented in this work help describe the behavior of polymer-CNC composites and may serve as a useful tool for process optimization of such materials. …
