  • What is nonionic polyacrylamide (NPAM) gel?
  • Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
  • Can phenolic resin cross-linked NPAM gel be used for water production control?
  • Conclusions In this work, a phenolic resin cross-linked NPAM gel was selected as an in-depth profile control agent for water production control. The gelation time and gel strength of the NPAM gel can be controlled by adjusting the NAPM polymer or cross-linker concentration.
  • Which polymers are used for the cross-linking reaction?
  • Previous studies have shown that anionic polymers and hydrophobic associative polymers are mainly used for the cross-linking reaction, and the cross-linking mechanism of these gel systems has also been described ( Zhao, 2010, You et al., 2010 ).
  • 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.
