title: [Spectroscopic analysis studies of organo-attapulgite/nylon 6 composites].
abstract: The surface organic modification of attapulgite with silane coupling reagent was studied by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Qrgano-attapulgite/nylon 6 composites with different content of attapulgite were prepared by means of melt blending, and the crystal structure and morphology were investigated. The results show that the surface content of Si, N and C of the modified attapulgite increased. Combined with the FTIR results, it was confirmed that an organic coating layer was formed on the surface of attapulgite. The adding of attapulgite does not change the crystal structure of nylon 6, but changes the crystallite size of nylon 6. The modified attapulgite was well dispersed in nylon 6 and the silane coupling coating on the attapilgite enhanced the interfacial adhesion.
