Gallery exchange ions

Properties of FH-PCH and SAP-PCH prepared by gallery templated synthesis using Ci6H33N(CH3)3+ as exchange ion Q+ and decylamine as co-template. 

Two fimdamental aspects of the organoclay determine the formation of epoxy nanocomposites from in-situ polymerization the abUity of the interlayer exchanged ion to act as a compatibUizer and render the layered silicate epoxyphilic , and the catalyzing effect of the exchanged ion on the polymerization reaction in the galleries [31]. 

Bio-nanocomposites based on layered clay can be stained with Safranine O by ion-exchange. Safranine O, a fluorescent dye, contains alumimun ion. Aluminum ion enables this dye to intercalate in clay galleries dming ion-exchange. Confocal microscopy can then be used to determine the extent of dispersion of clay during mixing or sonication (Yoonessi et al., 2004). 

The exchange of inorganic cations by organic surfactant ions in the clay galleries not only makes the organoclay surface compatible with monomer or polymer matrix, but also de-... 

Intercalation of phthalocyanines into the galleries of LDH also occurs via ion exchange [104], Like the prophyrins, the phthalocyanines are also oriented perpendicular to the cationic LDH. This is evident from the XRD pattern, which shows an increase in the basal spacing in LDH from 4.8 to about 18-25 A for LDH-phthalocyanine intercalates.
