摘要

水凝膠自1960年首次被提出後，發展距今已有約60年的歷史，主要透過吸收水份而產生膨潤行為，毒性低與人體組織相容性佳的特點，水凝膠已廣泛應用於各式領域，如：生醫材料、組織工程、再生能源…等，因此，為了拓展其應用性，水凝膠本身之機械強度成為科學家們首要注重之項目。本文將著重於介紹雙網絡水凝膠的特性與機制，並延伸歸納出近年來所發展出各式提高水凝膠之機械強度的化學結構設計以及新穎活性自由基聚合對水凝膠結構設計上的應用。

The term of ＂hydrogels＂ was first proposed at 1960, indicating that hydrogels have been developed for around 60 years. Hydrogels have the advantage of adsorbing large amounts of water, controable swelling ratios, and low toxicity which can be easily applied biomaterials, tissue engineering, green energy...an so on. In order to expand its applicability, the mechanical property of hydrogels has become one of the main focuses in resent years. Herein, we introduce characteristics and mechanisms of double network hydrogel, and extend the chemical structures in developments of high strength hydrogels in recent years and the application of robust living radical polymerizations to hydrogel design.
