Are polyacrylamide hydrogels a model system for highly elastic polymer networks?

This paper belongs to a series in which we use polyacrylamide hydrogels as a model system to study the mechanics of highly elastic polymer networks (Hassan et al., 2022; Kim et al., 2022; Liu et al., 2019; Wang et al., 2021a; Yang et al., 2019).

What are the functions of nonionic polyacrylamide PAM?

Therefore, nonionic polyacrylamide PAM has the functions of flocculation, dispersion, thickening, adhesion, film formation, gelation, and colloid stability. Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation.

What are nonionic DN and triple network hydrogels based on?

Herein, we prepared nonionic DN and triple network (TN) hydrogels based on polyacrylamide (PAAm) and poly ( N,N -dimethylacrylamide) (PDMA) with a high mechanical strength by sequential polymerization reactions.

What are polyacrylamide hydrogels?

Polyacrylamide hydrogels are commonly synthesized in academic and industrial labs, and have found extensive applications in biology, agriculture, and medicine (Caulfield et al., 2002).

What is polyacrylamide hydrogel (Pam)?

Polyacrylamide hydrogel (PAM) is widely used, but the soft hydrogel network is difficult to bear large stresses.

What is O-SIO 2 in Pam/SA double network hydrogels?

The double network hydrogels prepared by introducing polymer networks with excellent toughness into the SA network have excellent toughness , which Herein, we attached organically modified silica nanoparticles (o-SiO 2) to the surface of PAM/SA double network hydrogels by a weak ultrasonic field.
