“…To date, polyaniline has been intercalated into a variety of insulating host materials such as silicates, 2,3 uranium micas, 4 FeOCl, 5 hectorite, 6 zirconium phosphates, 7,8 double hydroxides, 9 layered semiconducting hosts such as V 2 O 5 10 and MoS 2 , 11 as well as network silicates such as zeolites, 12 and the recently discovered ordered mesoporous silicate MCM-41. 13 With the possible exception of MoS 2 and MCM-41, 14 these host materials are not available as large single crystals or tubules and therefore do not allow for macroscopic spatial alignment, although microscopic alignment within a crystallite has certainly been realised.…”

The intercalation and polymerization of aniline within the pores of a natural tubular Cu 2z -exchanged aluminosilicate clay known as halloysite is studied. The mesoscopic clay ®bres have internal diameters of approximately 180 A Ê and lengths of up to 20 mm and can be deposited as ®lms into which aniline is introduced from the vapour phase. The aniline composite was characterized by powder XRD, TGA, EPR, UV-Vis, XPS and IR spectroscopy. The present results con®rm the presence of polyaniline on the internal and external surfaces of the halloysite tubes, thus indicating that the composite material could act as a molecular wire. The polyaniline initially sorbed onto the external surfaces is in a reduced state and evolves toward a more oxidized state as the duration of exposure of the ®lm to aniline vapour increases.

“…Taking advantage of the 2D structure of zirconium phosphate (ZrP), Herzog‐Cance et al demonstrated the intercalation of aniline into the interlayer space of ZrP with both α and γ structures. The authors reported that the α and γ zirconium phosphate was brought to contact with either pure aniline or aniline diluted in acetone at various concentrations for 7 d to intercalate aniline into ZrP interlayer space ( Figure ).…”

Materials with layered structures at the nanoscale have lately drawn significant attention from engineers and scientists in the fields of physics, chemistry, and mathematics, due to the unique characteristics that originate from their hierarchical structure. The nanosized free space between each two adjacent layers, so‐called the interlayer space, is an attractive place that can be manipulated by incorporating different molecular species to generate novel physical and mechanical behaviors. This review highlights the latest studies and new important developments on possible methods of intercalating popular species such as hydrophobic and hydrophilic polymers into the interlayer spaces of layered materials. It also provides a description of intercalation processes as well as final applications for better understanding, as it is believed to be an effective factor in utilizing these materials in research and industry. Finally, this review gives perspectives on the future applicants of inorganic layered materials filled with polymers with different hydrophilicity properties.

“…Alkaline earth metal phosphates are important inorganics as well as biomaterials, and are found to have a wide variety of applications as heterogeneous catalysts [12,13], low thermal expansion ceramic materials [14], and ion exchangers [15]. As important raw and matrix materials of fluorescent powder, strontium (hydrogen) phosphates, however, received relatively less attentions [16,17].…”
