  • Can polyacrylamide polymer chains be cross-linked on a current collector?
  • Herein, polyacrylamide (PAM) polymer chains that are premixed homogeneously with various components are cross-linked on-site on the current collector via the condensation reaction with citric acid, forming a polar three-dimensional (3D) network with improved tensile properties and adhesion for both silicon particles and current collector.
  • Does cross linker concentration affect elasticity of polyacrylamide hydrogel?
  • According to this study, the elasticity of the polyacrylamide hydrogel was dependent on the ratio of acrylamide (monomer) and bis-acrylamide (cross-linker) concentration as it was being observed that the Young's modulus increased by increasing the concentration of the cross-linker. 5. Conclusion
  • What is polyacrylamide (PAM) used for?
