Compared to traditional hydrogel materials, organohydrogels have wider applications due to their special properties such as abilities of self-adaptive, freeze-tolerant and mechanically stable over a wide range temperature. In this paper, we prepared Poly (vinyl alcohol)/Poly (butyl methacrylate)-co-Poly (lauryl methacrylate) multiple network organohydrogels (MN-OHGs) by multiple swelling polymerization method. By tuning the components of heterogeneous networks, the swelling behaviors and the surface wettability in different solvents of MN-OHGs could be controlled. When the ratio of oleophilic polymer network (OPN) content to hydrophilic polymer network (HPN) content was 1:1.4, the MN-OHGs showed the highest mechanical properties (the elastic modulus could reach 8 MPa, and the toughness could reach 12 MJ/m³). Moreover, when the OPN/HPN ratio was 2/1, the MN-OHGs could maintain a stable volume in artificial seawater with mechanical properties enhanced by 47.3%. These characteristics demonstrated that the MN-OHGs were ideal candidates for functional materials which could be applied in complex environments.

与传统的水凝胶材料相比，有机水凝胶具有特殊的性能，例如在宽范围的温度下具有自适应，耐冻性和机械稳定性，因此具有更广泛的应用。在本文中，我们通过多次溶胀聚合法制备了聚乙烯醇/聚甲基丙烯酸丁酯-共聚甲基丙烯酸月桂酯多网络有机水凝胶（MN-OHGs）。通过调整异构网络的组成，可以控制MN-OHGs在不同溶剂中的溶胀行为和表面润湿性。当亲油性聚合物网络（OPN）含量与亲水性聚合物网络（HPN）含量之比为1：1.4时，MN-OHGs表现出最高的机械性能（弹性模量可以达到8 MPa，韧性可以达到12 MJ / ³米）。此外，当OPN / HPN比为2/1时，MN-OHGs可以在人造海水中保持稳定的体积，机械性能提高47.3％。这些特征表明，MN-OHG是可用于复杂环境的功能材料的理想候选材料。
