Synthesis of Zinc-Aluminium-Pamoate Nanocomposite using Direct Co-Precipitation and Ion-Exchange Methods
The intercalation of pamoate anions into the interlamellae of zinc-aluminium layered double hydroxide (LDH) was carried out by two different methods; direct co-precipitation and ion-exchange methods. The Zn/Al molar ratio, R of the LDH was set at 2 - 5 (x = 0.33 – 0.16, where x = [Al3+]/[(Zn2+ + A...

| description | The intercalation of pamoate anions into the interlamellae of zinc-aluminium layered double hydroxide (LDH) was carried
out by two different methods; direct co-precipitation and ion-exchange methods. The Zn/Al molar ratio, R of the LDH was
set at 2 - 5 (x = 0.33 – 0.16, where x = [Al3+]/[(Zn2+ + Al3+)] and the concentration of pamoate ion used was fixed at 0.02 M.
A sharp, intense and symmetrical peak could be observed from the XRD patterns for all the samples synthesized by direct
co-precipitation method, indicating a well-ordered nanolayered structure in the nanocomposite. However, the XRD patterns
of the nanocomposite prepared by ion-exchange method show that the second peak for (006) reflection are broad and not
symmetrical due to the overlapping of two peaks at 2q = 10°, which indicated the presence of LDH with nitrates as the
counter anion. The percentage of PA intercalated into the interlamellae of the nanocomposite prepared by ion-exchange
method is in the range of (29 – 45)%, which is lower than the one prepared by direct co-precipitation method, (43 – 51)%.
This shows that direct co-precipitation method yielded nanocomposites with higher loading of the organic moiety and better
crystallinity compared to the ion-exchange method. |
