However, there is no study about surface functionalization of HNT by curcumin and evaluation Curcumin its physico-chemical properties. Therefore, in the present work the chemistry of Cur absorption on the naked Crystallinity HNT was studied. The SEM, TEM images and FTIR spectra of HNT/Cur composite revealed the formation a Thermal stability complex between the external surface of HNT and Cur, a process that was led to surface roughness. TEM images Nanoﬁller and TGA curves also conﬁrmed the entry of Cur into lumen of HNT. Based on XRD analysis, after Cur absorption onto HNT, crystallinity was decreased in the surface
