Epoxy biopolymer hybrid hydrogels have excellent potential for load bearing applications, despite limited studies in this area. In this paper, a facile one-pot synthesis of epoxy/agar hybrid hydrogels has been reported. Infrared spectroscopy, rheometry, thermal, mechanical properties and immersion studies have been reported. An advantage of the hydrogels synthesized here is that they can be prepared in a shorter timeframe than conventional epoxy biopolymer hydrogels. Diethylene triamine was used as the cross-linker which induces gelation within five minutes at 90 °C. The mechanical properties of epoxy hydrogels prepared using diethylene triamine are found to be comparable to that of hydrogels prepared using long chain amine terminated poloxamers. The compressive toughness of the hybrid hydrogels increases by ~380% via the addition of 3 wt% agar in comparison with epoxy hydrogels. These hybrid hydrogels are elastic and biodegradable.

Epoxy agar hybrid hydrogel with enhanced compressive toughness was prepared using a combination of covalent and physical bonding. The hybrid hydrogels could be produced in very short time compared to conventional epoxy based hydrogels and show potential to be applied in load bearing applications

尽管在这一领域的研究有限，但环氧生物聚合物杂化水凝胶在承重应用方面具有出色的潜力。在本文中，已经报道了一种容易的一锅法合成环氧/琼脂杂化水凝胶。已经报道了红外光谱，流变学，热，机械性能和浸没研究。此处合成的水凝胶的一个优点是，与常规的环氧生物聚合物水凝胶相比，它们可以在更短的时间内制备。使用二亚乙基三胺作为交联剂，该交联剂可在90°C的五分钟内诱导胶凝。发现使用二亚乙基三胺制备的环氧水凝胶的机械性能与使用长链胺封端的泊洛沙姆制备的水凝胶的机械性能相当。与环氧水凝胶相比，通过添加3 wt％的琼脂，杂化水凝胶的抗压韧性提高了约380％。这些杂化水凝胶是弹性的且可生物降解的。
