Title: Study on effect of UV-Irradiation on Properties of EVOH/MMT Nanocomposite
Abstract: Concerned about the organic modification of the montmorillonite clay,and the modified montmorillonite was characterized by Fourier transform infrared spectrometer(FTIR),X-ray diffraction(XRD),the scanning electron microscope(SEM);simultaneously used the solution intercalation prepared ethylene-vinyl alcohol copolymer(EVOH)/montmorillonite(MMT)nanocomposite membrane;and treated it with UV-irradiation.The result indicated the modified montmorillonite clay surface became hydrophobic from hydrophilic;the level distance increased to 3.5 nm from 1.467 nm;the mechanical properties and barrier properties of composite membrane had improved after treated under UV-irradiation,at the same time the transparency of composite films was not affected.
