Chemical Structure and Reaction Scheme of Modified Bamboo Powder with Silane Coupling Agent
摘要
Abstract
The bamboo powder modified with the silane coupling agent of KH-560 (KB) was studied by X-ray photoelectron spec-troscopy (XPS) , X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscope. The modified mechanism was also investigated in this work. Results showed that the hydrolysis of KH-560 was found to enhance the attachment on the surface of bamboo powder by the formation of hydrogen bond and dehydration condensation. XRD analysis indicated that the degree of crystallinity of bamboo powder didn't change after the modification by KH-560. However, the reaction of bamboo powder and KH-560 was certified by the appearance of absorption of ether bond in FT-IR spectrum and the XPS peak of silicon at 101. 18 eV. At the same time, the binding energy of C1s changed from 288. 16 eV to 288.52 eV and the peak of oxygen atom ( attributed to C=O) at 530.98 eV disappeared. All results indicated that the reaction between bamboo powder and KH-560 didn't occur on the bamboo fibre due to the exist of the strong hydrogen bonding force, but on the aldehyde groups from lignin at the absence of mechanical force and chemistry reagent.关键词
