High resolution shear profile measurements in entangled polymers.
We use confocal microscopy and particle image velocimetry to visualize motion of 250-300 nm. fluorescent tracer particles in entangled polymers subject to a rectilinear shear flow. Our results show linear velocity profiles in polymer solutions spanning a wide range of molecular weights and number of entanglements (8< or =Z< or =56), but reveal large differences between the imposed and measured ...
متن کاملConstitutive Curve and Velocity Profile in Entangled Polymers during Start-Up of Steady Shear Flow
Time-dependent shear stress versus shear rate, constitutive curve, and velocity profile measurements are reported in entangled polymer solutions during start-up of steady shear flow. By combining confocal microscopy and particle image velocimetry (PIV), we determine the time-dependent velocity profile in polybutadiene and polystyrene solutions seeded with fluorescent 150 nm silica and 7.5 μm me...
متن کاملNon-Affine Shear Modulus in Entangled Networks of Semiflexible Polymers
We investigate the viscoelastic properties of entangled networks of semiflexible polymers. At intermediate time scales the elastic response of these networks to shear deformation is described by the plateau modulus G. Different scaling laws with polymer concentration c have been proposed based on the assumption that the deformation field is affine on all length scales. We develop a numerical ap...
متن کاملShear Damping Function Measurements for Branched Polymers
We present results for step-strain experiments and the resulting damping functions of polyethylene blends of different structures, including solutions of linear, star and comb polymers. Remarkably, an entangled melt of combs exhibits a damping function close to that for entangled linear chains. Diluting the combs with fasterrelaxing material leads to a more nearly constant damping function. We ...
متن کاملProbing the dynamics of high-viscosity entangled polymers under shear using Neutron Spin Echo spectroscopy
Neutron Spin Echo spectroscopy provides unique insight into molecular and submolecular dynamics as well as intraand inter-molecular interactions in soft matter. These dynamics may change drastically under shear flow. In particular in polymer physics a stress plateau is observed, which might be explained by an entanglement-disentanglement transition. However, such a transition is difficult to id...
