“…Recently, such nanostructural change has been applied to the control of the properties of the hybrids. For instance, the swelling and deswelling behaviors of poly-(N -isopropylacrylamide)-silica hybrid film in water triggered by temperature and pH has been reported [51]. Our group has also reported the reversible intercalation and deintercalation of phenol for the azobenzene-intercalated montmorillonite upon UV and visible light irradiation [52].…”

“…However, the swelling ratio decreases with clay increasing, for NAC25. It is perhaps because the crosslinking density increases and the bones of network became thicker, which is not fit for water absorbency [17,18].…”

In this paper, a series of P(NIPAM-co-AA)/Clay composite hydrogels (abbreviated as NAC gels) with high swelling ratio and excellent mechanical strength were synthesized and characterized by DMA, SEM, and IR. In NAC gels composed of a unique organic P(NIPAM-co-AA)/ inorganic (clay) network, the inorganic clay acts as a multifunctional cross-linker in place of an organic cross-linker as used in the conventional chemically cross-linked hydrogels (abbreviated as OR gels). The NAC gels exhibit excellent swelling ratio, and there was no detectable change in properties on altering the concentration of clay, while the swelling ratio tends to decrease slightly when C clay increases up to 25 wt%, which was revealed in swelling measurements. IR spectra show that clay has been intercalated by copolymers. Furthermore, results of DMA reveal that the composite hydrogel has an excellent mechanical strength by using a wide range of clay concentration, while the moduli improve with increasing C clay .

The subtle performance of a virus is closely related to its specific hierarchical structure, which is composed of a rigid shell and transverse, responsive, nanometer‐sized channels. Virus‐like structured colloids are of great interest for their potential applications, for example in drug delivery. Adequate knowledge of the structure and composition control of both colloids and mesoporous materials is significant in the design and synthesis of hierarchically structured colloids to mimic viruses. Some recent developments in the synthesis of composite colloids and mesoporous materials are summarized. Template synthesis is a major tool to control both the macroscopic morphology and microstructures of these composites, in which gel colloids and supramolecular structures from amphiphilic species are used as templates.
