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 ... WebJul 27, 2024 · Hydrogel has been an attractive biomaterial for tissue engineering, drug delivery, wound healing, and contact lens materials, due to its outstanding properties, including high water content, transparency, biocompatibility, tissue mechanical matching, and low toxicity.
WebHigh water content and ionic hydrogel lens materials were associated with greater dehydration (p < 0.0001 for both) than low water content and non-ionic materials. When dehydration was assessed as the difference in refractive index, only high water content was associated with dehydration (p < 0.0001). Conclusions: High water content and ionic ...
