WebNov 1, 2024 · The surface of many biological materials and some high water-content hydrogels have varying concentrations and gradients of macromolecular chains on the surface that emanate outward into the environment. The lubricity of hydrogels has been shown to improve by increasing the amount of water at the surface [ 1, 2, 3, 4, 5 ].
WebWater content also affected the swelling rate. However, the water content varied with the hardness. Taking MCS as an example, the correlation between pK a, water content, the swelling rate, and hardness is shown in Figure 6. A smaller value of pK a led to a higher level of dissociation, resulting in more hydration and a faster swelling rate ...
