Interface Reaction and Molecule Recognition Among Wood Flour, Amino Silane Coupling Agent and POE-g-MAH Compatibilizer

The interface reaction and molecule recognition among wood flour, amino silane coupling agent and maleic anhydride grafted polyolefin compatibilizer were studied by fourier transform infrared analyzer (FTIR), scanning electron microscope with an energy dispersive X-ray spectroscopy (SEM-EDS) and X-ray photoelectron spectra (XPS). According to molecule recognition principles, γ-APS in the wood flour surface was identified by SEM-EDS. A new state of N1 s at 401.33 eV appears in XPS as γ-APS and maleic anhydride grafted polyolefin compatibilizer are introduced simultaneously, which shows the occurrence of reaction between γ-APS and maleic anhydride-grafted polyolefin compatibilizer, and amino is formed.
