摘要: The surfaces of naturally occurring halloysite nanotubes were functionalized with γ-aminopropyltriethoxysilane (APTES), which was found to have a substantial effect on the loading and subsequent release model dye molecule. APTES mostly anchored at internal lumen surface through covalent grafting, forming covered by aminopropyl groups. 32% greater than that unmodified sample, from dramatically prolonged as compared one. Dye low pH 3.5 approximately three times slower 10.0. These results demonstrate organosilane functionalization makes an external trigger for controlling guest controlled release.
