Abstract
Cinnamaldehyde (CINN) is an organic guest anion, the main constituent of cinnamon oil was intercalated into zinc layered hydroxides (ZLHs) by ion exchange method. CINN has been reported can killed mosquito larvae. The powder
X-Ray diffraction (PXRD) indicates a successful intercalation of CINN into the interlayer galleries of ZLHs matrix
when 1.0 g of ZnO with 0.08M of CINN was used forming zinc layered hydroxides-cinnamaldehyde (ZCINN)
exhibiting basal spacing expansion, 21.2Å. Fourier transform infrared (FTIR) results supported and confirmed the
intercalation of CINN as both ZnO and CINN functional groups appeared in ZCINN spectrum. The thermal stability
property of the ZCINN was enhanced as compared to the anion, CINN. Field emission scanning electron microscopy
(FESEM) image of ZnO showed a nonuniform granular-like structure transforming into flaky structure with various
sizes after intercalation of CINN took place. These results indicate that it is possible to design and develop the
nanocomposites containing larvicide for further investigations.
