Synthesis and thermal properties of organically modified palygorskite/fluorinated polyurethane nanocomposites

Synthesis and thermal properties of organically modified palygorskite/fluorinated polyurethane nanocomposites
Zhiqiang Zhu, Xia Wang, Ying Li
In this article, fluorinated polyurethane (FPU) nanocomposites filled with organic modified palygorskite (Pal) were synthesized and characterized by Fourier transform infrared, X-ray diffraction, thermogravimetric analysis (TGA), and scanning electron microscope individually. The Pal nanorods were modified with 4,4′-methylene (MDI) by chemical bond. TGA results showed that there are almost 27 wt % of 4,4′-methylene grafting or absorbing on Pal nanorods’ surface. Compared with neat FPU, FPU nanocomposites exhibited somewhat increase in the soft segment glass transition temperature and decrease in the hard segment glass transition temperature. It means the compatibility between soft segment and hard segment becomes better than neat FPU. TGA results also showed that the thermal stability of FPU nanocomposites improved with increasing modified Pal loadings. Pal showed good compatibility with the FPU matrix through scanning electron microscope test results. And, the introduction of Pal into FPU matrix will not affect migration of fluoride side chain. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 45460.
