Summary

This study compares optical measurements and computer simulations of phase-separating polymer blends under shear flow. Results show shear rate affects structure differently based on which phase is more viscous.

Area of Science:

  • Polymer Science
  • Materials Science
  • Fluid Dynamics

Background:

  • Phase-separating polymer blends exhibit complex morphology under flow.
  • Understanding shear-induced structural changes is crucial for material properties.

Purpose of the Study:

  • To investigate the structure and morphology of phase-separating polymer blends under simple shear flow.
  • To compare experimental optical measurements with computer simulations.
  • To analyze the influence of viscous asymmetry on blend morphology.

Main Methods:

  • Optical measurements of polymer blend structure and morphology.
  • Computer simulations of sheared phase-separating binary mixtures.
  • Analysis of the two-point composition correlation function.

  • Measurement of string width along neutral and velocity-gradient directions.

    • Main Results:

    • Both experiment and simulation reveal distinct shear responses depending on the dispersed or continuous nature of the more viscous phase.
    • A power-law decay with an exponent of 1/3 was observed for string width along the neutral direction when the more viscous phase is dispersed.
    • Simulations indicated a consistent power-law decay (exponent 1/3) for mean string width along the velocity-gradient direction, irrespective of the dispersed phase.

    Conclusions:

    • The study highlights subtle differences in shear response based on phase viscosity and distribution.
    • Power-law relationships govern the decay of structural features with increasing shear rate.
    • Experimental and simulation data provide complementary insights into sheared polymer blend behavior.
