我们制备了一种基于同时形成两种聚合物网络（结冷胶和聚丙烯酰胺）的互穿聚合物网络水凝胶。结冷胶网络是离子交联的，而聚（丙烯酰胺）网络是共价交联的。这些凝胶可以恢复第一个压缩周期的 53 +/- 4% 的滞后和后续周期的 90 +/- 9%。
We have prepared an interpenetrating polymer network hydrogel based on the simultaneous formation of two polymer networks, gellan gum and poly(acrylamide). The gellan gum network is ionically cross-linked, while poly(acrylamide) network is covalently cross-linked. These gels can recover 53 +/- 4% of the hysteresis of the first compressive cycle and 90 +/- 9% of subsequent cycles.
