Kinetically controlled cross-linking processes produce mechanically distinguishable hydrogels using identical precursor chemistry. The oxime ligation demonstrates tunable reaction kinetics with pH and buffer strength, which induce changes in the structural features of hydrogels and determine their mechanical properties. Small-angle neutron scattering and swelling studies provide an insight into how structural properties correlate with mechanical properties for this hydrogel system.
动力学控制的交联过程使用相同的前体化学方法制备出具有机械差异的水凝胶。肟连接反应显示出随pH值和缓冲强度可调的反应动力学,这会引起水凝胶结构特征的变化并决定其机械性能。小角中子散射和溶胀研究为该水凝胶体系的结构性质与机械性能之间的关联提供了深入了解。
