Reaction mechanism of nanocomposite fibers

Hydrolyzed ASP and the surface hydroxyl groups of HNTs consisting of aluminol groups at the internal surface of the lumen are grafted to potentially improve the dmg loading and delay of drug release (Levis and Deasy, 2003) in drag-delivery application. 

Notwithstanding that HNTs have siloxane with only a few hydroxyl groups on their external surfaces, the modification of external surfaces of HNTs helps to increase their 

The surface treatment of HNTs is normally achieved through oligomerization that requires a high-temperature process. As the modification of HNT-ASP has not been subjected to heating to high temperatures in this study, the dominant mechanism can be the direct grafting of ASP to HNT surfaces, which is a favorable modification used
