  • What is next polyacrylamide hydrogel?
  • NEXT Polyacrylamide hydrogels are widely used as lost circulation materials and plugging agents in oil and gas production engineering. In these practical applications, controllable gelation time, favorable gel strength, and interface adhesion strength are desirable properties for polyacrylamide hydrogels.
  • Do polyacrylamide hydrogels have a good adhesion behavior?
  • In these practical applications, controllable gelation time, favorable gel strength, and interface adhesion strength are desirable properties for polyacrylamide hydrogels. However, there have been no systematic studies of these properties, particularly for adhesion behavior.
  • Do cationic polyacrylamide hydrogels have a higher interface adhesion strength?
  • Interestingly, cationic polyacrylamide hydrogels possess a higher interface adhesion strength but less bulk cohesion. These findings are helpful to comprehend molecular weight and concentration effect on polyacrylamide hydrogel performances and the relationship between hydrogel network structure and macroscopical properties.
  • What are the applications of polyacrylamide based hydrogels?
  • In polyacrylamide (Aam) based hydrogels, plenty of applications has been found. Cross-linked polymers which can imbibe a large amount of water can be used in various fields such as biotechnology, biomedical engineering, food industry and separation process.
