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.

Are polyacrylamide hydrogels a 2d-model soft substrate?

Polyacrylamide (PAAm) hydrogels are widely adopted as 2D-model soft substrates for investigating cell-material interactions in a controlled in vitro environment.

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.

Does enrichment increase adhesion strength in polyacrylamide hydrogels?

By raising enrichment of functional groups, the adhesion strength increases from 1315 to 1913 Pa. In addition, adhesion behaviors of cationic and anion polyacrylamide hydrogels were also examined in contrast to NPAM hydrogels.
