利用壳聚糖制备创伤修复材料是有化学交联法和物理交联法。其中“离子交联法”离子交联法属于化学交联法还是物理交联法？ 离子交联法与“通过静电作用”交联在一起是一个意思吗？谢谢！ |

离子作用力是属于化学交联，静电作用力可能算物理交联吧 我自己的感觉是，金属离子和polymer侧基产生作用力一般用离子键；polymer（+）和polymer（-）作用一般用静电作用 p.s. Hydrogels are network polymers – composed principally of hydrophilic, cross-linked macromolecules – that absorb water, aqueous solutions, or physiological fluids, but remain insoluble due to their network structure.The cross-links may be strong chemical linkages, temporary entanglements, or weak chemical interactions.Strong chemical cross-links, for example, are commonly made by free radical polymerization of vinyl monomers in the presence of a small amount of cross-linker, which is a comonomer having two or more functional vinyl groups. This cross-linking mechanism is based on covalent bonding in the hydrogel frame or backbone; however, hydrogels may also be chemically linked by reactive sites in pendent groups, which form bridges in the gel between neighboring macromolecules. Interactions between side groups may include ionic associations, or weaker chemical forces such as hydrogen bonding, dipole interactions, and van der Waals forces. Physical networks or physical portions of networks include entanglements and crystallites. In addition, physical interactions in an otherwise amphorous hydrogel may provide some mechanical integrity to hydrogels in their swollen state. Ultimately, gel structure and thermodynamic compatibility with the surrounding solution determine swelling behavior. From Polymer Science: A Comprehensive Reference, Volume 9 |
