Investigation on Structural, Morphological and Relaxometric Properties of Lamellar Zrp Modified with Long Chain Amine
Listed in DataCite
In order to search nanofiller for controlling release of drugs lamellar α-zirconium phosphate (α-ZrP) was modified with ether-amine oligomer (E-A).
Description
Synthesis and chemical modification followed specific reaction conditions and different EA:ZrP ratios. Infrared spectra showed strong interaction between P-OH and NH2 groups.
Thermogravimetric curves showed that ether-amine oligomer was incorporated by ZrP. Interlamellar space of α-ZrP increased at least four times indicating intercalation. The relaxometry analysis indicated that α-ZrP molecular mobility changed according to the ether-amine amount.

The scanning electron microscopy/energy dispersive analysis revealed the presence of octadecylamine inside the α-ZrP galleries. The results showed that P-OH group (Brønsted acid) and amine group (Brønsted base) reacted to each other, resulting in an ionic bond PO- + 3HN-[-(CH2-CH2-O)m-(CH2-C-H(CH3)-O)n-]. Partially intercalated nanofiller were achieved.
