Summary
This summary is machine-generated.

Mechanical deformation significantly impacts water transport in soft solids like polydimethylsiloxane (PDMS). This study reveals that PDMS permeability to water decreases dramatically with increased stretching, affecting mechano-permselectivity.

Area of Science:

  • Materials Science
  • Soft Matter Physics
  • Chemical Engineering

Background:

  • Large deformations in soft solids alter molecular structure and device geometry, influencing properties like mass transport.
  • The interplay between mechanical deformation and flux is critical for understanding transport phenomena in soft materials.

Purpose of the Study:

  • To develop and demonstrate a platform for simultaneously characterizing mechano-permselectivity.
  • To investigate the transport of water through polydimethylsiloxane (PDMS) under mechanical stress.

Main Methods:

  • Utilized micron-sized, cylindrical PDMS chambers filled with NaCl solution, encapsulated by PDMS thin film membranes.
  • Applied osmotic pressure by placing chambers in a high water potential environment, inducing water flow and membrane bulging.
  • Developed a combined model of membrane flux and nonlinear elasticity to analyze time-dependent responses.

Main Results:

  • A deformation-dependent permeability model was necessary to accurately capture the observed time-dependent response.
  • Water permeability through PDMS decreased by nearly an order of magnitude (from 2 × 10^-12 to 5 × 10^-13 m^2 s^-1).
  • This decrease in permeability was primarily attributed to a significant reduction in membrane thickness with increasing biaxial stretch (from 1 to 2.75).

Conclusions:

  • The study highlights the significant impact of mechanical deformation on mass transport properties in soft solids.
  • The developed platform effectively characterizes mechano-permselectivity, demonstrating a strong dependence of PDMS water permeability on mechanical strain.
  • Findings are crucial for designing soft material-based devices where mechanical deformation influences transport phenomena.
