This paper describes a conceptual design of hierarchical composite hydrogels. The hydrogel materials comprise MoS2 flakes and interpenetrating polymer networks, and further exhibit controlled release and tunable strength that are caused by the synergistic combination of select components. In terms of design, MoS2 flakes initiate radical polymerization of chosen monomers and simultaneously provide physical cross-linking points, both of which afford a primary composite network. Then, the sequential formation of additional networks results in functional, hierarchical, composite hydrogels. Therefore, we were able to demonstrate double-network hydrogels as a stimuli-responsive vector for programmed release of cargo molecules in response to heat or light or to form triple-network hydrogels showing tunable mechanical strength owing to intermolecular interaction between charged monomers and MoS2 flakes. The design concept would be expanded by incorporating other chalcogenides or functional monomers, which advance the properties and functionalities of materials and broadens the versatility of nanocomposite hydrogels.

MoS2 嵌入的互穿网络复合水凝胶可控制染料的释放并可调节强度
本文描述了分层复合水凝胶的概念设计。该水凝胶材料包含MoS 2薄片和互穿聚合物网络，并进一步表现出由选定组分的协同组合引起的受控释放和可调强度。在设计方面，MoS 2薄片引发所选单体的自由基聚合，同时提供物理交联点，这两者都提供了主要的复合网络。然后，附加网络的顺序形成产生功能性、分层的复合水凝胶。因此，我们能够证明双网络水凝胶作为刺激响应载体，用于响应热或光而程序性释放货物分子，或形成三网络水凝胶，由于带电单体和MoS 2之间的分子间相互作用而显示出可调节的机械强度薄片。通过掺入其他硫属化物或功能单体，可以扩展设计概念，从而提高材料的性能和功能，并拓宽纳米复合水凝胶的多功能性。
