Poplar was intercalation modified with decompress/compress impregnation process and UF-Na-MMT as impregnation solution.X-ray diffraction（XRD）,Scanning electron microscope（SEM） and Fourier transform infrared spectroscopy（FTIR） were employed to detect and analyse.SEM observation showed that there were a lot of UF resin and Na-MMT in the catheter,and a part of it close integrated with the poplar fiber and cell wall.The study of XRD and FTIR indicated that the crystallinity of modified poplar decreased,free hydroxy reduced,associated hydroxyl...
