中文摘要：

Hydrogels 由于他们的优秀 biocompatibility 和多刺激应答在过去的二十年引起了可观的注意。他们在与织物工程，传感器和 biomedicine 有关的域里有大量应用程序。他们的应用被在 hydrogels 和另外的底层之间的 hydrogels 和界面的相互作用的表面性质强烈影响。特别地， hydrogels 的表面 wettability 和粘附作为药搬运人和创伤调味品材料决定他们的应用。不过，有 hydrogels 的表面 functionalization 策略的系统的讨论的缺乏。因此，这评论与另外的稳固的底层在总结 functionalizing 的策略瞄准 hydrogels 和结合的 hydrogels 的表面。它也探索挑战和 hydrogels 的界面的工程的未来观点。

英文摘要：

Hydrogels have drawn considerable attention in the past two decades due to their excellent biocompatibility and multi-stimuli responsiveness. They have a wide range of applications in the fields related to tissue engineering, sensors and biomedicine. Their applications are strongly influenced by the surface properties of hydrogels and the interfacial interactions between hydrogels and other substrates. In particular, the surface wettability and adhesion of hydrogels decide their applications as drug carriers and wound dressing materials. Nevertheless, there is a lack of systematic discussion on the surface functionalization strategies of hydrogels. Therefore, this review aims at summarizing the strategies of functionalizing the surfaces of hydrogels and bonding hydrogels with other solid substrates. It also explores the challenges and future perspectives of interfacial engineering of hydrogels.
