Water Dynamics in Polyacrylamide Hydrogels

tigate the ultrafast molecular dynamics of water and a small molecular anion solute, selenocyanate (SeCN−), in polyacrylamide hydrogels.

Water Dynamics in Polyacrylamide Hydrogels. - Abstract

Polymeric hydrogels have wide applications including electrophoresis, biocompatible materials, water superadsorbents, and contact lenses. The properties of hydrogels involve the poorly characterized molecular dynamics of water and solutes trapped within the three-dimensional cross-linked polymer networks.

Transparent hydrogel with enhanced water retention capacity

Specially, polyacrylamide hydrogel containing high content of lithium chloride can retain over 70% of its initial water even in environment with relative humidity of only 10% RH. The excellent water retention capacities of these hydrogels will make more applications of hydrogels become possible.

Study on Large Deformation Behavior of Polyacrylamide

Meso-scale models for hydrogels are crucial to bridge the conformation change of polymer chains in micro-scale to the bulk deformation of hydrogel in macro-scale. In this study, we construct coarse-grain bead-spring models for polyacrylamide (PAAm) hydrogel and investigate the large deformation and fracture behavior by using Dissipative Particle Dynamics (DPD) to simulate the crosslinking process.

Physical entanglement hydrogels: ultrahigh water content but

The as-prepared hydrogels can swell high content of water to achieve very low polymer fractions (∼1 wt%). Although they contain an ultrahigh water content and possess an ultra-soft nature (low to ∼10 Pa storage modulus), these physical entanglement hydrogels (PEH) are tough and stretchable (>6 times) due to the free-sliding dynamics of the

A polymer network can imbibe copious amounts of solvent (water) and swell, and the resulting state is known as a hydrogel. In this study, we have made the modification for the all-atom consistent valence force field (CVFF) to investigate the swelling property of polyacrylamide (PAM) hydrogel by molecular dynamics simulation.
