  • 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.
  • What is an anionic polyacrylamide?
  • Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
  • Which comonomer is used for the production of anionic polyacrylamides?
  • The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid. These anionic polymers can be prepared as various mono- and divalent metal salts and other positively charged inorganic and organic counterions of the polymerization of acrylic acid with acrylamide (see Fig. 34.4 ).
  • What is polyacrylamide?
  • Polyacrylamide is a term that has various definitions. For our purposes here, we will simply term polyacrylamide as a polymer that contains an acrylamide monomer at some level. Polyacrylamides make up the largest group of polymers in comparison to other synthetic polymeric polyelectrolytes.
